A comparative study of the surgical management of carpal tunnel syndrome by mini-transverse wrist incisions versus traditional longitudinal technique

This prospective randomized study aims at evaluating the safety and effectiveness of a mini-transverse wrist incisions technique (without endoscope) for carpal tunnel release in comparison with the traditional open technique, which is still considered as the gold standard. Forty patients with a carpal tunnel syndrome were individually randomized into the trial (mini-transverse wrist incision) (20 patients) and control group (traditional longitudinal technique) (20 patients). The mean period of follow-up was 3 months. Subjective analysis of the results included the symptomatic relief and the return to daily activities and work, and objective outcome study included examination for operative time, scar tenderness, length, esthetics and comparison of pre- and post-electromyography studies. After the operation, 90% of patient with control and 80% of the trial group were satisfied by symptomatic relief. There were no differences between the two groups in electrophysiological parameters. The scar length in mini-transverse wrist incision technique was (1.4 ± 0.17 cm) and (5.15 ± 0.26 cm) in the traditional one. Return to daily activities was faster in the mini-transverse incision. We conclude that the result of mini-transverse wrist incisions without the use of endoscope is safe and comparative to gold standard approach with additional benefits.
