Abstract

BACKGROUND: Endoscopic carpal tunnel release was developed by Okutsu and Chow in 1989. Many reports have indicated that endoscopic carpal tunnel release diminishes postoperative pain and accelerates the recovery time. METHODS: In a series of 1278 carpal tunnel release procedures (in 948 patients), 1214 were performed with a modified Menon endoscopic method and the remaining 64 with an open procedure. The patients with idiopathic carpal tunnel syndrome were followed for at least 3 months. RESULTS: Of the endoscopic release patients, 80.9% recovered grip strength equal to or greater than preoperative levels within 4 weeks, whereas in the open procedure group, the rate was only 59.3%. The difference was statistically significant (p = 0.00011). An immediate complication was one median motor nerve severance. There were 24 conversions to a conventional open procedure during endoscopic release. In the endoscopic group, 81% developed scar tenderness over the thenar crease, 31% developed new sensory disturbance, and 4% developed pillar pain. CONCLUSION: Endoscopic release facilitated the recovery of grip strength and diminished the frequency of scar tenderness. However, neurovascular injury should be carefully prevented.
