Diagnosis: Morton’s (Interdigital) Neuroma Discussion Interdigital (Morton’s) neuroma is a common source of pain in the ball of the foot, usually occurring in either the 3rd or 2nd webspace.

“Neuroma” is a misnomer, as it represents fibrosis around the digital nerve rather than a true tumor.

Several factors are considered to be risk factors for the development of Morton’s neuromas, including ill-fitting shoes, certain foot deformities, and repetitive trauma from running.

Both ultrasound and MRI are excellent modalities for diagnosing Morton’s neuromas.

Ultrasound has the added advantage of allowing for image-guided cortisone injection or ablation.

If noninvasive treatments are not successful, surgical resection is curative.
