Stromal Vascular Fraction-Enriched Fat Grafting for the Management of Symptomatic Neuromas

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 graft longevity.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.

1. Surgical Procedure

1. To approach the neuroma, make a skin incision over the previously diagnosed neuroma site in the distal third of the forearm.
2. Under the usage of surgical binocular loupes magnifier glasses (2.5 - 3.5X), continue to dissect the subcutaneous tissue and identify the involved nerve proximal to the neuroma.
   1. Subsequently, follow the nerve distally and identify the neuroma (b....
