Document Summary

I: vertebral border and inferior angle of scapula. O: long head- tubercle above glenoid cavity of scapula, short head- coracoid process. O: long head- infraglenoid tubercle, lateral head- lateral and posterior side of humerus, medial head- posterior side of humerus. O: medial epicondyle of humerus, and coronoid process of ulna. O: medial epicondyle of humerus, coronoid process of ulna, radius. I: distal and middle phalanges of each finger. I: tendon of extensor digitorum of index finger. The carpal tunnel is a narrow passage formed anteriorly by the flexor retinaculum and posteriorly by the carpal bones. Carpal tunnel syndrome is caused by inflammation of the digital tendon sheaths, fluid retention, excessive exercise, inflection, trauma, and/or repetitive activities that involve flexion of the wrist. The median nerve is vulnerable to compression and when it gets compressed it causes sensory changes to the hand and muscle weakness (carpal tunnel syndrome) resulting in pain, numbness and tingling fingers.
