OBJECTIVE: To study the method and effect of endoscopic two-portal one-way releasing procedure for cut of transverse carpal ligament and decompression of median nerve.
METHODS: Eleven female patients (13 sides) with primary carpal tunnel synrome underwent endoscopic two-portal one-way releasing procedure, there were 3 left hands, 6 right, and 2 both. All the subjects had hypesthesia in the radial three and half finger's tip with a positive, Tinel sign of median nerve at wrist; 11 cases had thenar myatrophy in which 4 had opposition dysfunction. Under local anaesthesia, the proximal incision was located at the point of the proximal carpal transverse striation level between palmaris longus and flexor carpi radialis. The outlet was chosed the junction of the parallel line of the ulnar side of thumb and proximal extending line of middle ring fingers' long axis while the thumb was in abduction position. The length of each incision was only one centimeter. The hook knife was inserted to the proximate of the transverse carpal ligament, then, the transverse carpal ligament was completely released form the proximal to the distal end by hook knife under the endoscope monitor.
RESULTS: The results showed that both pinch and grip function was satisfied and no complications occurred at 4 to 20 months followed-up. S3+ M3 or more has been reached in 3 months after operation.
CONCLUSION: The endoscopic two-portal one-way releasing procedure is an easy and effective method for the treatment of carpal tunnel syndrome.
