Endoscopically assisted release of the superficial radial nerve.

ABSTRACT

INTRODUCTION: The feasibility of endoscopically assisted decompression of the superficial radial nerve at the midportion and distal forearm was assessed. SURGICAL TECHNIQUE After a 3 cm longitudinal skin incision at the Tinel's sign at the forearm, the subcutaneous tissue is dissected until forearm fascia is detected. The fascia is opened cautiously under direct visualization and the superficial radial nerve is identified. Blunt forceps mobilize the subcutaneous tissue upon the fascia before the illuminated speculum is inserted. Then further dissection of the fascia is performed proximally using the Metzenbaum scissors. After further blunt tunneling by forceps the endoscope is introduced proximally in order to release the superficial radial nerve completely. Then the speculum is inserted distally to identify the nerve within the subcutaneous tissue. Then further visualization is facilitated using the endoscope. CONCLUSION: The endoscopically assisted release of the superficial radial nerve may be feasible in a safe and sufficient way.
