Objective To study the effectiveness of transverse carpal ligament release for carpal tunnel syndrome (CTS) with arthroscopic "two-portal" technique under local anesthesia. Methods Transverse carpal ligament was released with arthroscopic "two-portal" technique in 31 patients with CTS between November 2002 and August 2008. There were 4 males and 27 females, aged 24-71 years (mean, 52 years). The disease duration was 1 month to 14 years (mean, 42 months). According to the guidelines of Bin Tian, 20 sides were rated as grade I, 16 sides as grade Ⅱ, and 5 sides as grade Ⅲ before operation. The sensation was S2+ in 7 cases, S3 in 19 cases, and S3+ in 5 cases. The muscle strength of the abductor pollicis brevis and opponens pollicis muscles was grade 2 in 5 cases, grade 3 in 14 cases, and grade 4 in 7 cases. Michigan hand function scoring system (MHQ) was used to evaluate the function of the hand before and after operation. Results All incisions healed primarily, and no complications of median nerve injury and adhesion occurred. All of the 31 patients were followed up 6-11.8 years (mean, 9.6 years). After operation, numbness and paresthesia of fingers were relieved (S4); the muscle power returned to grade 4 in 8 cases, and to grade 5 in 23 cases. The MHQ scores of function, daily life, work, pain, appearance, and satisfaction were improved significantly at 6 months postoperatively when compared with preoperative ones (P<0.05). There was no relapse. Conclusion Arthroscopic "two-portal" technique is an effective surgical procedure for relieving the compression symptoms on the median nerve from carpal canal, so it is helpful to functional recovery of the median nerve. The long-term effectiveness is definite.
