Abstract
A new technique of endoscopic carpal tunnel release using a 1.5-cm longitudinal palmar
incision was used in 280 cases. The incision allows identification of the superficial
palmar arch as well as the median nerve and its branches. A new knife/sleeve device
that attaches to a standard 4-mm endoscope was created to simplify the procedure.
The flexor retinaculum is endoscopically divided proximally into the distal forearm;
the “interthenar fascia” (fascia superficial to transverse carpal ligament) can be
preserved. Early postoperative results include a mean overall return to work and full
activity of 14 days. Postoperative pinch and grip strengths were near or at the preoperative
level by weeks after surgery. One third of patients required no postoperative analgesics
with minimal scar, ulnar pillar, and radial pillar tenderness.
