Begin with an anesthetized patient experiencing symptomatic pain from a suspected neuroma in the superficial branch of the radial nerve.
Neuromas are painful nerve growths that develop after nerve injury.
Make a skin incision in the distal forearm.
Dissect the subcutaneous tissue to expose the nerve and trace its course distally.
If no neuroma is detected, perform neurolysis by removing scar tissue around the nerve.
Make small stab incisions around the skin incision and insert blunt cannulas, directing the tips toward the nerve.
Secure the cannulas with an adhesive dressing.
Suture the main incision.
Inject Stromal vascular fraction or SVF-enriched fat graft around the nerve through the cannulas.
The fat graft forms a mechanical barrier, preventing abnormal nerve sprouting.
SVF, a mix of regenerative cells isolated from adipose tissue, minimizes fat resorption and enhances graft longevity.
Remove the cannulas, close the stab incisions, and bandage the surgical site.
To approach the neuroma, make a skin incision over the diagnosed site, which in this case is 3 centimeters distal to the wrist. To identify the involved nerve proximal to the neuroma, wear surgical binocular loops, and dissect the
