The carpal tunnel is an osteofibrous canal situated in the volar wrist. It contains the median nerve and nine tendons: the flexor pollicislongus, the four flexor digitorum superficialis and the four flexor digitorum profundus. Patients presenting carpal tunnel syndorome often complain about pain, tingling and numbness in the first 3 fingers and lateral half of the IV th finger. While initial treatment may be medical, patients often require surgical release of the transverse carpal ligament. Even though the surgical procedure is considered to have low difficulty it is accompanied by a significant morbidity and sometimes persistent symptoms post-surgery. In this study we dissected both hands of 9 formalin fixed cadavers and measured fixed landmarks in order to enhance the safety of a surgical decompression of the median nerve.
