Morton Neuroma

Morton neuroma is a painful thickening and irritation of an interdigital nerve in the forefoot, most often between the third and fourth toes, and is an important cause of burning or sharp forefoot pain. Repetitive compression from walking, narrow footwear, or altered foot mechanics can inflame the nerve and surrounding tissue, producing numbness, tingling, or a sensation of a pebble beneath the foot. Clinical assessment, supported when needed by imaging, helps distinguish Morton neuroma from stress injury and other conditions. Treatment may include footwear modification, orthotics, activity changes, injections, or surgical nerve decompression or removal, guiding individualized patient care.

Source: Brakkee, E. M., et al. Surgery and Behavioral Testing in the Tibial Neuroma Transposition Model in Rats. J. Vis. Exp. (2023).This video demonstrates a procedure to generate a rat tibial neuroma transposition (TNT) model. After exposing the tibial nerve in the hind leg of an anesthetized rat, transect the nerve. Next, create a subcutaneous tunnel, thread the severed nerve through the tunnel, and suture it in place. In the absence of a target for reinnervation, disorganized axonal...

Source: Zimmermann, S., et.al. Stromal Vascular Fraction-enriched Fat Grafting for the Treatment of Symptomatic End-neuromata. J. Vis. Exp. (2017)This video demonstrates the surgical procedure for neurolysis and stromal vascular fraction (SVF)-enriched fat grafting in the management of symptomatic neuroma. Neurolysis removes adhesion tissue to restore nerve gliding, while SVF-enriched fat grafting is applied around the nerve to create a protective barrier, support nerve healing, and enhance...

This protocol describes the tibial neuroma transposition model, which entails a lesion of the tibial nerve with subsequent transposition of the proximal nerve end toward a subcutaneous pretibial or lateral position. Behavioral testing of neuroma pain and plantar hyperalgesia is quantified using Von Frey monofilaments.

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The foot is a complex structure composed of numerous bones and articulations. It provides flexibility, is the essential contact point needed for ambulation, and is uniquely suited to absorb shock. Because the foot must support the weight of the entire body, it is prone to injury and pain. When examining the foot, it is important to remove shoes and socks on both sides, so that the entire foot can be inspected and compared.
