This cadaveric study evaluates the margin of safety and technical efficacy of mini open carpal tunnel release performed using Knifelight? (Stryker Instruments) through a transverse 1 cm wrist incision. A single investigator released 32 wrists in 17 cadavers. The wrists were then explored to assess the completeness of release and damage to vital structures including the superficial palmar arch, palmar cutaneous branch and recurrent branch of the median nerve. All the releases were complete and no injury to the median nerve and other structures were observed. The mean distance of the recurrent motor branch to the ligamentous divisions was 5.7 ? 2.4 mm, superficial palmar arch was 8.7 ? 3.1 mm and palmar cutaneous branch to the ligamentous division was 7.2 ? 2.4 mm. The mean length of the transverse carpal ligament was 29.3 ? 3.7 mm. Guyon?s canal was preserved in all cases.
