Wrist anatomy carpal tunnel

Figure 13-1. Pictorial representation of the anatomy related to carpal tunnel syndrome. Nerves both left and right views), blood vessels (right view), tendons and tendon sheaths (right view) pass through the carpal region of the wrist. The large ligament over the carpal region helps keep tissues in place during wrist articulation. V arious forms of inflammation and disorders in the wrist and hands can result from repetitive motions.

Although the soft tissue anatomy of the forearm is complex due to the high number of muscles involved in the spectrum of wrist and fingers movements, musculoskeletal pathology amenable to US examination is relatively uncommon in this area. Only a few specific conditions affecting the median nerve proximal to the carpal tunnel level merit separate consideration.
