Abstract
|
|
|
The cause of carpal tunnel syndrome is the compression of median nerve at the carpal
tunnel. Surgical release of transverse carpal ligament is indicated if symptom persists in spite
of conservative treatment. Release of transverse carpal ligament without neurolysis is
sufficient to relieve the symptom. Several methods of endoscopic treatment have developed
and the good results were reported. We reported the results of 13 cases treated with
endoscopic carpal tunnel release in 12 patients from March 1995 to July 1996. Eleven cases
treated with one portal technique(Agee) and 2 cases treated with two incision
technique(Chow). Average follow-up period is 11 months(4-19 months). Average age
48.5(35-56) years old. There were 11 women and 1 male. Average duration of symptoms
before the operation was 9 months. According to Cseuz's creiteria, excellent results was
obtatined in 77% of patients. Tingling sensation diminished within 24 hours after operation in
six patients. Two thenar atrophy didnt recovered at 8 months after operation. Three scar
tenderness occured. Relief of symptoms was achieved quickly when endoscopic method was
used but several technical pitfall must be avoided.
