Foot and Ankle Spotlight
In Colorado, adventure is always afoot
Colorado’s lifestyle creates a wide array of foot and ankle demands. From hiking and running to cycling and skiing, CU Anschutz foot and ankle specialists care for one of the nation’s most active populations.

Q&A
A student of anatomy, Renaissance man Leonardo da Vinci recognized what many of us take for granted: the human foot is remarkably complex. Each foot contains 28 bones, 33 joints, and more than 100 muscles, tendons, and ligaments supporting the weight of our bodies and working in concert with every step to keep us stable and moving
When even a small part of that system is disrupted, the effects can ripple upward. Over time, compensation can alter gait, affect alignment and balance, and place stress on joints and cartilage throughout the body
With April being Foot Heath Awareness month, we sat down with Dr Kenneth J Hunt, Professor and Chief of Foot and Ankle to talk about this foundational marvel of the body, and what it takes to keep them functioning at their best.
What
is one mistake you see patients make when it comes to foot health?
KJH: One of the biggest mistakes people make is pushing through pain. Continuing activity despite symptoms can worsen an existing problem or create a new injury Paying attention to your body, resting when appropriate, and seeking evaluation from a specialist when symptoms persist can prevent a minor issue from becoming a major one.
Because of both the magnitude and frequency of forces placed on the foot and ankle during activity, chronic conditions are very common These can include tendonitis, bone stress injuries, and chronic ligament injuries
What are some of the most common foot and ankle injuries you see?
KJH: The most common injury I see is ankle ligament injury This may be a severe ankle sprain, a high-grade ligament injury, or chronic recurrent ankle sprains that lead to ankle instability Ankle instability can also lead to additional problems, particularly involving the peroneal tendons on the outside of the ankle.
The second most common condition involves the Achilles tendon We certainly see Achilles tendon ruptures, but Achilles tendonitis and tendon degeneration are far more common These conditions are especially prevalent among runners, particularly trail runners
The third common issue is bone stress injury, often referred to as a stress fracture These injuries typically occur in distance runners and other repetitive-use athletes Repeated high-frequency loading can eventually overwhelm the bone’s ability to recover, leading to stress reactions or fractures
These three conditions ankle instability, Achilles tendon disorders, and stress fractures are among the most common problems we see in active individuals.
of art.
Leonardo da Vinci
How does foot and ankle health affect the rest of the body?
KJH: The foot is the first part of the body to contact the ground and the last part to leave it during walking or running Because of this, even small changes in alignment or function can significantly affect the entire kinetic chain Problems in the foot and ankle can contribute to knee pain, hip pain, pelvic dysfunction, and low back pain.
One issue we commonly see occurs after an ankle injury. Patients often allow the pain to resolve but never fully restore their gait mechanics or strength As a result, they may develop additional injuries or chronic symptoms elsewhere in the body Appropriate rehabilitation is critical Even a brief course of physical therapy can help restore strength, mobility, and proper movement patterns while reducing the risk of future injury
The “kinetic chain” is the idea that the body moves as a connected system, with joints, muscles, and nerves working in concert.
Like a bicycle chain in motion, each link influences the next meaning even small changes can ripple through the body as a whole.
2
What can people do to prevent foot and ankle injuries?
KJH: The first step is an appropriate warm-up routine. Stretching muscles, tendons, and ligaments, as well as incorporating joint mobility exercises, should be part of any activity regimen
Second, wear appropriate footwear to significantly reduce injury risk. Many people assume they can participate in any activity using whatever shoes they happen to have available. However, shoes are specifically designed for particular activities.
If you’re hiking, wear hiking shoes
If you’re playing tennis or pickleball, wear court shoes
If you’re running, wear running shoes
Another important consideration is the use of insoles. Every person’s foot structure is different. Some individuals do very well with over-the-counter inserts, while others require customized orthotics to properly support their foot mechanics

Illustration of how a walking foot strikes the ground
Shown are three stages:
1) before the foot strikes the ground, the rounded arch is poised like a steel spring
2) as the foot hits the ground, the impact flattens the arch and the Achilles tendon stretches 3) the arch springs back to shape and the Achilles tendon shortens/recoils
It’s an easy decision to overlook—but the wrong shoes can quickly remind you why it matters, as Dr. Hunt himself has experienced.
“I play tennis a couple of times a week. One day I arrived at a match and realized I had forgotten my tennis shoes. I decided to play in running shoes instead. Afterward, I developed knee pain, foot pain, and Achilles soreness. I was uncomfortable for several weeks simply because I was wearing the wrong footwear for the activity.
It’s an easy mistake to make because many of us think, ‘I could have done that when I was younger.’ But as we get older, using the right equipment becomes increasingly important.”
Tell us about the Gait Laboratory at the UCHealth Foot and Ankle Center.
KJH: Gait analysis can be as simple as having an experienced clinician observe someone walking. However, at the UCHealth Foot and Ankle Center, we have a dedicated gait laboratory that provides much more sophisticated analysis Using 8 cameras, motion-tracking technology, and specialized sensors, we can evaluate every aspect of gait, including:
Joint motion
Muscle activation patterns
Walking mechanics
Functional movement abnormalities
This technology allows us to identify the primary source of a patient’s symptoms and distinguish it from secondary compensatory problems
The information can guide:
Surgical planning
Rehabilitation strategies
Orthotic prescriptions
Footwear recommendations
Performance optimization

What makes the University of Colorado Foot and Ankle program unique?
KJH: First, we are a team of multidisciplinary experts providing comprehensive care. Our Foot and Ankle Center includes orthopedic foot and ankle surgeons, podiatrists, primary care sports medicine physicians, physical medicine and rehabilitation physicians, physical therapists, and engineers and gait specialists
We also have advanced diagnostic tools, including weight-bearing CT scanning, fluoroscopy, ultrasound imaging, and motion analysis through our gait laboratory This allows us to care for everything from simple overuse injuries to complex deformities and traumatic injuries
Second, we are committed to advancing the field through research and innovation. Our team remains at the forefront of emerging treatments and technologies, and in many cases, we are actively helping develop and evaluate these treatments For example, our group is a regional leader in total ankle replacement and custom talus replacement surgery For patients with severe injuries, infections, tumors, or arthritis involving the talus bone, we can utilize custom 3D-printed talus implants. These implants replace a damaged talus and preserve motion. Historically, many of these patients required fusion of the ankle and hindfoot, which eliminates motion. While fusion can be effective, it can limit function on uneven terrain and during recreational activities Custom talus replacement and modern ankle replacement technologies provide important motion-preserving options for appropriately selected patients and can help them maintain an active lifestyle.
Third, our specialized expertise. Our providers focus specifically on foot and ankle conditions, and we have assembled a highly skilled and experienced team dedicated to this area of orthopedic care Whether patients are asking about new surgical procedures, biologic therapies, rehabilitation approaches, or performance strategies, we have the expertise to provide evidence-based guidance
Did You Know?
One of the major advances in foot and ankle surgery is the development of minimally invasive techniques. These procedures use very small “keyhole” incisions to access joints, tendons, and bones. CU Anschutz Orthopedics specialists are highly experienced in these techniques and their application across a wide range of conditions.
Examples include:
Minimally invasive Achilles tendon repair
Treatment of Achilles tendonitis
Bunion correction
Correction of foot deformities
Benefits may include:
Less pain
Reduced swelling
Faster recovery
Earlier return to activity
For many active patients, these techniques have significantly improved outcomes and helped accelerate a safe return to movement.
Specialized care, close to home.
Comprised of nationally renowned orthopedic surgeons, our clinical services are available throughout the front range in the most comprehensive and complete network of care.
The “48 Hour Rule”
Listen to your body If you develop pain and it persists despite 48 hours of rest, it is worth seeking evaluation from a healthcare professional More severe symptoms such as sudden pain, a popping sensation, bruising, or swelling should be evaluated sooner

Reaching Beyond Relief: A Moonshot for a Cure
Colorized x-ray films of knees of a patient with chronic osteoarthritis showing joint narrowing (cartilage loss)
May is Arthritis Awareness Month—but for millions worldwide, awareness is a daily reality marked by pain that, for many, can become debilitating.
Researchers at CU Anschutz, CU Boulder, and Colorado State University are working to change that reality. Backed by federal support, a multidisciplinary Colorado team is developing regenerative therapies designed not simply to relieve symptoms, but to restore cartilage and bone and potentially reverse osteoarthritis (OA) itself
What began as an ambitious idea has quickly become one of the most closely watched osteoarthritis research programs in the country and one with the potential to transform care for millions.
From Managing Disease to Reversing It
For decades, osteoarthritis treatment has focused on a single goal: helping patients manage pain Medications, injections, physical therapy, and, ultimately, joint replacement surgery can help restore function and improve quality of life But none address the underlying disease itself For the nearly 33 million Americans living with osteoarthritis, the progression of joint damage has long been viewed as inevitable That challenge is what inspired the inaugural Novel Innovations for Tissue Regeneration in Osteoarthritis (NITRO) program The initiative tasked researchers with pursuing something many considered impossible: identifying technologies capable of curing osteoarthritis rather than simply treating it
Two years ago, some of these therapies were just ideas— reflecting the moonshot nature of this program from the very start."
Karin Payne, PhD Associate Professor
In just two years an extraordinary pace in a field where treatment advances have historically been incremental the Colorado team developed a suite of regenerative approaches designed to repair damaged tissue inside the joint One potential treatment is an annual injection that delivers medication directly into the joint, stimulating regeneration over time. Another combines engineered proteins with novel biomaterials that recruit the body's own progenitor cells to repair damaged cartilage and bone Together, these approaches seek to harness the body's natural healing capacity in ways that have not previously been possible.
Researchers now plan to move these technologies toward the studies required for human clinical trials which could begin as early as 2028

A Colorado Collaboration Designed for Impact
The NITRO project represents more than a scientific breakthrough It is also a powerful example of what can happen when experts across institutions unite around a shared goal The effort brings together clinicians, engineers, veterinary scientists, regulatory specialists, community engagement experts, and translational researchers from CU Anschutz, CU Boulder, and Colorado State University. At its height, the project involved as many as 40 to 50 researchers working simultaneously across disciplines, each contributing a critical piece of the puzzle
At CU Anschutz, researchers collected cartilage and bone tissue donated by patients undergoing joint replacement surgery. The cells from these tissues, which would have otherwise been discarded, were sent to CU Boulder and tested with newly developed biomaterials to help scientists better understand how cells behave and respond
Materials created at CU Boulder were then tested in laboratory and animal models at CSU, creating a highly integrated research pipeline from discovery to translation The team views this collaborative structure as one of the project's greatest strengths
It has been very exciting for me to be part of this effort. NITRO underpins a set of crossinstitutional collaborations that now has the potential to move the needle both for researchers seeking new solutions and for patients who need effective approaches to address their OA.

Hope On the Horizon
While a cure remains the ultimate goal, the work already represents a significant shift in how researchers think about osteoarthritis
Instead of accepting degeneration as unavoidable, investigators are asking whether damaged joints can be regenerated and whether millions of patients might someday have an alternative to a lifetime of managing symptoms
For the people who live every day with osteoarthritis, that's more than an exciting scientific question. It's a future worth pursuing.

Community for a Cure
Researchers have invested heavily in community engagement Through listening sessions, educational outreach, and statewide conversations with patients, the team has worked to understand barriers to care while creating practical resources for people living with osteoarthritis. Those efforts include educational materials available in two languages, and opportunities for patients to learn about future clinical trials
Researchers have created a growing community for patients, caregivers, and anyone interested in learning more about osteoarthritis research and future clinical trial opportunities Email
Seeing Trouble Before It Starts
Even as researchers pursue a bold, long-term goal a future without osteoarthritis there is equal urgency in understanding the disease at its earliest stages If a cure represents the ultimate breakthrough, early detection may be one of the most powerful tools we have today offering new ways to intervene, preserve joint health, and change the trajectory of the disease before it fully takes hold.

In this study, a muti-disciplinary team of University of Colorado researchers looked at people who had undergone ACL (anterior cruciate ligament) reconstruction a group known to be at higher risk for developing osteoarthritis later in life About six months after surgery, their knees may feel stable, but subtle changes can already be happening inside the joint
The findings were telling Compared to healthy knees, reconstructed knees showed signs of increased strain in key areas of the joint, meaning the cartilage was experiencing more stress than it should Among patients who reported ongoing symptoms like pain or discomfort, these changes were even more pronounced.
Interestingly, traditional MRI measures of cartilage composition could detect differences between injured and healthy knees but they weren’t as effective at distinguishing who was actually feeling symptoms The newer, motion-based imaging approach provided a clearer picture of which patients might be at greater risk
MRI Images
Using advanced MRI, researchers imaged the knee at rest and under gentle, repeated pressure revealing how it performs under stress, like a shock absorber in motion
Structure, composition, and function are captured in sequence to show what the cartilage looks like, the health of the tissue, and how it performs under stress

Why It Matters
Osteoarthritis doesn’t happen overnight. In many cases, the earliest signs of joint damage begin long before pain, stiffness, or changes on an X-ray appear. The challenge has always been catching those changes early when there’s still a window to slow or even prevent long-term damage.
These findings point to a powerful shift in how we think about joint health By detecting subtle, early changes in cartilage mechanics, clinicians may soon be able to identify patients at higher risk for osteoarthritis— months or even years before the disease becomes visible or debilitating.
That opens the door to earlier, more personalized interventions, from targeted rehabilitation to activity modifications, with the goal of preserving joint health for the long term

Advocating for Athlete Care
Advocacy is an extension of patient care. This spring, orthopedic leaders brought that commitment to Capitol Hill, highlighting the policies needed to protect athletes and the physicians who serve them amid a rapidly changing sports landscape
Convened by AAOS and partner organizations, the briefing focused on preserving access to care across all levels of sport while addressing growing legal and regulatory pressures on team physicians.
Panelists including AOSSM President and CU Anschutz Professor and Chief of Sports Medicine
Eric C. McCarty, MD emphasized the importance of medical independence, continuity of care across state lines, and protections for clinicians providing good-faith care As the landscape of athletics shifts, speakers warned that increasing liability risks could deter experienced physicians from serving on the sidelines, ultimately affecting athlete safety.
The discussion highlighted a broader push among physicians, policymakers, and even elite coaches to stabilize the care structures athletes rely on ensuring that medical decision-making remains centered on health, not external pressures
Every championship, every scholarship, and every comeback begins with something most people never see: trusted medical care. If we lose the physicians willing to serve athletes, we put athlete health at risk.

Demonstrating perfect posture and an impeccable gait, boneanchored limb patient, Nina Urbina (Pierce, CO) tests a newer technology osseointegration prosthetic by walking on uneven terrain outside the CU Medicine Center for Prosthetics
The indominable spirit and determination of our bone-anchored limb patients to redefine on their own terms what is possible for themselves is a powerful reminder of what’s can happen when expertise, innovation, and human resilience come together. N e w p o s s i bi l i t i e s
For the second consecutive year, the Limb Restoration team consisting of doctors, nurses, physical therapists, case workers and program coordinators have given patients a place to do just that in the form of the Osseointegration Bootcamp, a two day event in April that brought together patients from more than a dozen states in a shared space of support and community to navigate the unique and often challenging journey that limb difference presents Hosted across our UCHealth clinics and the CU Medicine Center for Prosthetics, the event offers immersive education, peer support, and direct engagement with care teams marking a significant step forward in patient-centered programming and innovation. Participants also received personalized feedback from our research team on studies to which they’ve directly contributed, offering valuable insights into their individual cases In addition, they took part in prosthetic foot trials and engaged in group rehabilitation sessions led by the UCHealth PT OI Team
“Redefining what’s possible” has become part of our mantra as a department. We embrace it for what it says about us as clinicians and researchers undeterred in our pursuit to push boundaries and never accept the status quo in patient care But redefining what’s possible isn’t just central to our mission it’s what we see in our patients, and no one lives this philosophy more than bone-anchored limb patients Quite literally having to learn again to walk or to use their arms, our patients have boldly pushed through tremendous physical and emotional trauma and emerged on the other side strong and determined not to let limb difference hold them back
We can talk about innovation and outcomes, but here—you see it. This is where our work comes to life, as patients come together, support one another, and push beyond what they thought was possible alongside a team fully committed to guiding them every step of the way. The medicine matters, but it’s the combination of care and community that makes this program truly transformative.

After years of struggling with traditional prosthetics, Joshua Karczewski set out in search of a better way forward. Now living with osseointegration, he reflects on the physical and emotional journey—from injury to innovation— and the purpose he’s found in helping others navigate life after limb loss.
Can you share a little bit about your story?
My name is Joshua Karczewski, I’m from Bella Vista, Arkansas. I became an amputee in June 2013 after a motorcycle accident I was hit by a drunk driver It essentially tore off the lower part of my leg and shattered my femur They were able to save the femur, but I had a below-the-knee amputation
For the next eight years, I used traditional prosthetic sockets. I probably saw 12 different prosthetists trying to get the right fit, but I never really got there. There was always too much movement in the socket and too many changes throughout the day with activity I’m very active biking, hiking and sweating would lead to irritation and infections Then I would be off the prosthesis for weeks while it healed, only to start the cycle again It got to the point where I was three weeks on, three weeks off That’s when I started seriously looking for an alternative.
How did you find out about Osseointegration at CU Anschutz?
I had been researching osseointegration (OI) for a number of years I even spoke with a team in Australia but it was incredibly expensive no insurance coverage and I would have had to stay there for months. That just wasn’t realistic. So I kept watching to see when it would become more available in the U S Around 2020 or 2021, I talked with another clinic about my chronic pain and asked if they were doing OI They weren’t familiar with it but said they’d be willing to try I didn’t want to be the first case I didn’t want to be the guinea pig
I started looking more seriously and found a list of U.S. surgeons through an online community. At the time, there were only a few Dr Stoneback had the most experience After speaking with the team and coming out to meet them, it was clear they had a well-rounded approach not just the surgery, but the aftercare, physical therapy, everything It just felt like they had their system figured out. That mattered a lot. You can have a big medical center do the surgery, but without the right aftercare, you’re missing a huge part of the process. So I moved forward here. I had surgery in August 2021 and returned for therapy in October
What has been the biggest change with OI?
They told me going in that I’d start to feel things again connection to the ground, how I move in space I underestimated that Even in a socket, I thought I felt things pretty well I’ve always had a high tolerance I could walk in almost anything. But now, with OI, I actually feel the prosthetic in a completely different way. I can feel small things clicking, subtle movements in the foot.
That’s been huge, especially when testing different prosthetic feet I can give real feedback about what works for my activities It also helps inform research what should be improved and what actually matters in design With a socket, I don’t think you fully benefit from the technology With OI, you’re using the mechanics of the prosthesis in a much more complete way.
Community seems important to you. Can you talk about that?
I’m a certified peer volunteer wi Coalition I’ve been doing that fo Even before OI, I’ve always just helping others get through wha through. And so I would just pu with my prosthetist and say ‘He anyone coming through and the through something like this, let m can speak with them’ And so t create some of that community
I’ve been with folks who are decision to have an amputation the other side who had an eme an amputation and they’re sittin bed and don’t know what to do have all those scary questions t was in that same position. Som a friend of a friend One of our p -his wife was about to get an am because of cancer so I spoke w because that’s what we should doing it You know, I wish I coul I had the time to do more
Can you share an exam of that impact?
I remember seeing a post in a lo group from a mother whose son severe accident and was likely g leg He was 19, just starting his like everything was over I reached out and offered to her Those conversations matte patient but for the family. Ampu everyone around you. Families a support you, but they’re also de own emotions.
I’ve also talked to people ch amputation after years of failed sometimes without family suppo is helping them see all sides th but also what their family might There’s a lot to process, and ha who understands both the phys emotional side can really help.
Anything else you’d like to share with us?

April 2026 OI Bootcamp
A Personal Reflection by Nina Urbina
Attending the OI Bootcamp this past April was an unexpectedly emotional and empowering experience for me I went in hoping to learn, but I left feeling deeply connected not just to the technology, but to the people who live this journey every day
One of the most meaningful parts of the bootcamp was meeting prosthetists, clinicians, and amputees from all over the country Each conversation felt like a window into someone’s lived reality Some people shared their struggles, others shared breakthroughs, and many of us found ourselves bonding over the small, everyday challenges that only another amputee truly understands. Those moments of honesty and connection stayed with me.
We also had the rare opportunity to try on the newest microprocessor knees and feet something I had never experienced in such a hands on, supportive environment Being able to actually feel the difference in stability, responsiveness, and movement was powerful It wasn’t just a product demo; it was a chance to ask real questions, talk openly about our specific needs, and explore what mobility could look like for each of us For many people there, it was the first time they felt truly heard by professionals who understood the nuances of limb loss
Another highlight was spending time with Adaptive Adventures, an organization that brought specialized equipment designed for people who are differently abled. Watching them demonstrate adaptive sports gear and mobility tools was inspiring. It reminded me that mobility isn’t only about walking it’s about reclaiming joy, hobbies, confidence, and the parts of life that make us feel whole
This experience didn’t just teach me about new technology - It gave me stories, faces, and moments I’ll carry with me It deepened my empathy and strengthened my commitment to helping others navigate their own mobility journeys with clarity and compassion It reminded me of the strength, humor, and resilience that exist in this community And it made me proud to be part of it

From laboratory discovery to lifechanging care, a growing network of sarcoma experts is transforming what’s possible for patients.
Sarcoma care has always required a different kind of approach It’s rare, complex, and often unpredictable which means progress depends on more than a single discovery A willingness to share knowledge across disciplines and institutions is essential
At the second annual Rocky Mountain Sarcoma Symposium, that kind of collaboration was on full display. Clinicians, scientists, and care teams from CU Anschutz, CU Boulder, Colorado State University, and leading institutions across North America came together with a shared goal: to move promising research beyond the lab and into patient care
“To me, this is now a premier annual scientific meeting that I look forward to all year long—a perfect blend of basic and translational research framed by cutting edge clinical medicine talks that provides an excellent reminder of who we do this work for.”

Visiting faculty including Janai Carr-Ascher, MD, PhD (UC Davis), Patrick Grohar, MD, PhD (University of Michigan), Ashleigh Guadagnolo, MD, MPH and Valerae O Lewis, MD (MD Anderson Cancer Center), Robert Maki, MD, PhD (Memorial Sloan Kettering Cancer Center), Michael Monument, MD, MSc (University of Calgary), and Jane Underdown, MD (University of Utah Health) brought national perspective to discussions spanning discovery, treatment, and survivorship.
That translation—from bench to bedside— was a constant theme. In sessions on basic and translational science, researchers are zeroing in on how sarcomas develop and change over time, opening the door to more precise, targeted treatments. New approaches in immunotherapy, including next-generation CAR T-cell strategies, are being designed to better recognize and attack cancer cells bringing the possibility of more personalized care into sharper focus
In a uniquely collaborative twist, some of that work is happening across species Studies in canine osteosarcoma are helping researchers better understand metastatic disease and test new therapies, accelerating insights that may benefit both animals and people
At the same time, advances in clinical care are reshaping what treatment looks like for patients right now. New systemic therapies are expanding options for difficult-to-treat tumors like chondrosarcoma, while evolving strategies in surgery and radiation are helping control disease with greater precision
Just as important, these approaches are increasingly focused on life after treatment Surgeons are prioritizing techniques that restore form and function, not just remove tumors. Radiation oncologists are refining therapies to reduce long-term side effects. And across the board, teams are working to better predict how patients will respond so treatment can be adjusted earlier, and more effectively
For pediatric and young adult patients, that comprehensive view is especially critical Efforts to better understand genetic risk, disease progression, and long-term outcomes are helping shape care that looks beyond survival toward quality of life and prevention.
What’s emerging is a more connected model of care one that brings together national research and clinical expertise, and the shared insight to move faster than any one program could alone Sarcoma remains a formidable challenge But the momentum is real And for patients, that progress steady and collaborative is beginning to change what’s possible
Together, we are building the preferred sarcoma center in the Rocky Mountain Region, with national reach advancing research, expanding clinical trials, and offering new hope to patients.

Over a Decade of Hand Surgery Outreach
In regions with limited access to care, a single week can change the course of many lives – and their communities.
Since 2014, Dr. Fraser Leversedge, Chief of Hand, Wrist & Elbow Surgery and Co-Director of the Brachial Plexus and Peripheral Nerve Injury Program at the University of Colorado Anschutz, has led Touching Hands outreach missions to Ruth Paz Hospital in San Pedro Sula, Honduras As Team Leader of this international outreach program for the American Society for Surgery of the Hand (ASSH), he coordinates volunteer surgical teams that travel to Honduras twice each year to provide specialized hand and upper extremity care to patients who would otherwise have little or no access
The most recent mission, in May 2026, brought together a multidisciplinary team of 25 hand surgeons, anesthesiologists, nurses, hand therapists, and trainees from across the United States, including Duke University, Brown University, the University of New Mexico, Shriners Children’s Northern California, and several private practice groups.
The week began with a team-building activity followed by a full-day clinic, where the team evaluated 138 patients approximately 60% adults and 40% children Patients presented with a wide range of conditions, from congenital deformities and traumatic injuries to chronic disabilities and complex nerve disorders, many after years without access to specialty care. Over the course of the week, the team performed 57 surgeries and three minor procedures Most were complex reconstructive cases that also provided opportunities to teach local surgeons

Since 2014, the trip has provided a global health experience to over 65 hand surgery fellows and 25 orthopedic and plastic surgery residents – many of whom have participated in subsequent outreach programs.
For patients, surgery can be life-changing, restoring the ability to work, care for family, attend school, and engage more fully in daily life Over the past decade, Touching Hands teams have provided surgical and non-surgical care to hundreds of patients Their gratitude is evident in follow-up visits from previous brigades and in the smiles that greet the team each year.
“The immediate goal is to provide exceptional care and a brighter future to individual patients, but also to create something that is lasting developing local expertise so that our influence continues long after we leave ” -FL
For local surgeons, the team's clinical teaching helps expand expertise and increase the availability of specialized care Dr Leversedge has also returned to Honduras on numerous occasions to participate in educational courses and surgical skills training for local and regional surgeons. In recognition of these contributions, he was awarded honorary membership in the Honduras Orthopedics and Traumatology Society in 2025
Each trip is also a memorable experience for the volunteers Approximately 18–20 participants from across North America and occasionally Europe, Japan, and South America quickly come together as a multidisciplinary team, with every member playing a leadership role in an intensely collaborative and impactful week
The team also experiences local culture through visits to a textile factory, delivering gifts to boys’ and girls’ orphanages, and spending time at a local school whose students often serve as interpreters during the busy clinic
“As the end of the week draws to a close, the Touching Hand team has accomplished a great deal, but each of us realize that we have gained just as much as we have given, through the unique team experience that resets and re-energizes each of us for what we enjoy every day at home ”

A Full Circle Moment in the Operating Room
When Gerry Wienholt met his anesthesiologist before his total knee replacement he wasn’t expecting to learn the physician shared a close, personal connection with the surgeon who had treated his spine just two years earlier
Bryan Nycz, MD, of Boulder Valley Anesthesiology (an independent physician group that partners with UCHealth), is married to Nicole Look, MD, the orthopedic spine surgeon who performed Gerry’s original procedure linking two chapters of his care in an unexpected way
That connection became part of an already remarkable journey one that, for Gerry, started with a surprising moment of recognition. At his consultation appointment before spine surgery, he didn’t know Dr Look by her professional name; to him, she was simply “Nikki” from Yoga Pod It wasn’t until she walked into the room that he realized the physician he was entrusting with his care was someone he already knew from a very different setting
After restoring function in his spine, Gerry returned to CU Medicine for knee replacement, placing his trust in a new surgical team led by orthopedic surgeon Jessi Phillips, MD, who replaced his right knee in February and his left knee this past May Even in the moments leading up to surgery, the sense of familiarity continued his preoperative nurse, Brandy Ramirez recognized him not just as a patient, but as a fellow member of the same Boulder, CO Yoga Pod community shared by Drs. Look and Phillips.
For Gerry and his wife, Nicole who together own Yoga Pod the overlap felt especially personal, weaving together the spaces where they live, work, and find community What began as two separate procedures became a seamless, deeply connected experience one shaped by clinical expertise, compassionate care, and the kind of personal links that make a large health system feel unexpectedly small and personal.

Dr. Nicole Look is an orthopedic spine surgeon specializing in cervical and lumbar conditions including myelopathy, stenosis, disc herniations, spondylolisthesis, and spine trauma helping patients regain function and quality of life.
From my spine surgery to both knee replacements, the continuity of care was remarkable. But what truly set my CU Medicine experience apart was the personal thread running through it all. Having my amazing medical staff and my personal community overlap so uniquely made the entire experience very special. It gave my wife, Nicole, and me a deep sense of peace and trust every step of the way.

Building the Future of Musculoskeletal Science
Over the past four years, the University of Colorado’s Interdisciplinary Training in Musculoskeletal Research Program has grown into a vibrant, collaborative community dedicated to advancing discoveries that improve bone, joint, muscle, tendon, and rehabilitation health.
Housed within the Department of Orthopedics and the Colorado Program for Musculoskeletal Research, this NIH-funded T32 program brings together trainees and faculty from across all four CU campuses, as well as partner institutions throughout Colorado, to tackle musculoskeletal disease from many different angles, ranging from basic biology and engineering to rehabilitation science and clinical care
The program's collaborative environment is further strengthened by the Mack Clayton Endowment, whose support has helped build a statewide research ecosystem that fosters trainee development, interdisciplinary partnerships, and innovative musculoskeletal research with the potential to improve patient care
The program was created to address a national need for highly trained scientists capable of working across disciplines to accelerate new therapies and technologies for patients with orthopedic conditions
Since its launch in 2022, the program has supported 13 predoctoral and postdoctoral trainees working in 10 different research laboratories, while expanding its faculty network to 34 nationally recognized investigators across 19 departments. Trainees have collectively contributed more than 40 peerreviewed publications in leading journals, presented research at major national meetings, and transitioned into outstanding next-step careers in academia, biotechnology, and clinician-scientist training programs.
What is a T32?
A T32 is a prestigious National Institutes of Health (NIH) grant given to universities to fund predoctoral and postdoctoral research training.
It provides stipends, tuition, and career development for earlycareer scientists in biomedical, behavioral, and clinical fields, to prepare them for independent, faculty-level careers
Institutions must undergo rigorous peer review to secure T32 funding, and only top-tier research universities receive them
As part of this continued momentum, we highlight two recent postdoctoral fellows now stepping into the next phase of their careers as independent investigators and orthopedic clinician-scientists Their work reflects the program’s defining strength: a commitment to translational research that bridges engineering, biology, and patientcentered orthopedic care
Julia Matthias, MD, PhD completed postdoctoral research training under the co-mentorship of Kenneth Hunt, MD and Michael Zuscik, PhD, within the Department of Orthopedics at CU Anschutz Her work focused on uncovering the molecular drivers of post-traumatic ankle osteoarthritis, particularly the role of synovial tissue in disease progression after injury Using advanced transcriptomic and molecular profiling approaches, Dr. Matthias identified pathways involved in extracellular matrix remodeling and Wnt signaling that may contribute to joint degeneration. She contributed to important publications examining ankle osteoarthritis biology and helped develop an NIH R21 research proposal investigating Wnt signaling as a therapeutic target in posttraumatic arthritis Dr Matthias will complete a second PhD in Clinical Sciences in 2027 and has matched into an orthopedic surgery researchtrack residency at the University of Rochester, where she plans to continue building a career as an orthopedic clinician-scientist focused on osteoarthritis research
Hannah Zlotnick, PhD completed postdoctoral training in the laboratory of Jason Burdick, PhD, at CU Boulder’s Department of Chemical and Biological Engineering and BioFrontiers Institute. Her research focused on developing sophisticated “joint-on-a-chip” systems that model how joint tissues respond to injury and inflammation, with the goal of improving understanding of osteoarthritis and other degenerative joint diseases Dr Zlotnick contributed to several high-impact publications in journals including Science Advances, Proceedings of the National Academy of Sciences, and Advanced Healthcare Materials, while helping advance new biomaterials and diagnostic technologies for orthopedic applications In recognition of her work, she was named a Rising Star in Engineering Health Dr Zlotnick recently accepted a tenure-track Assistant Professor position in the Department of Orthopaedic Surgery and Rehabilitation at Wake Forest University School of Medicine, where she will continue developing engineered systems to study joint injury and repair
