seCtion 2: Understanding the asPen™ sPinoUs ProCess FiXation system
The Aspen™ Spinous Process Fixation System (also known as Aspen™) is a less invasive fixation device utilized during lumbar spinal fusion procedures. Like pedicle screws, rods, hooks or plates used to fixate the posterior spine, the Aspen device is a type of posterior fixation instrumentation intended to rigidly hold vertebrae together while spinal fusion occurs. The Aspen device consists of a pair of small, titanium plates connected by a central, hollow barrel. Small spikes on the plates grip the spinous processes for rigid fixation, intended to rigidly hold the vertebrae in place while spinal fusion occurs.
The Aspen System is: • Posterior spinal fixation • Adjunct to fusion for surgical treatment of degenerative disc disease, spondylolisthesis, tumor and trauma • Used to restrict, prevent, or inhibit spinal segmental mobility • Indicated for use as posterior, non-pedicle supplemental fixation as an adjunct to fusion
The Aspen System is NOT: • A procedure • A spacer or an interspinous process decompression device • A free floating decompressive/distraction device (e.g. X-Stop®) • A device to be used with a primary stenosis diagnosis • Used to preserve spinal mobility
