Do i have carpel tunnel syndrome or martin gruber syndrome or both? dr. 1 did nerve conduction study at wrist and elbow of median nerve and recorded at apb and found increased latency and decreased amplitude with diagnosis of carpel tunnel syndrome. he a

Martin : Martin gruber anastamosis is a connection between the median nerve or the anterior interosseus nerve proximally in the forearm and the ulnar nerve distally. There are several variations but the main think is that it is a very cpomon anatomic finding and has nothing to do with carpal tunnel syndrome. It is an incidental finding that may protect ulnar innnervated structures in those with compression of the ulnar nerve but it is not a syndrome by itself. It is important because recognition of the anomaly is something that an electromyography should appreciate during a complete study. If only the median nerve is studies to one finger , say the index then the martin gruber anastamosis may be undiscovered. (an aastomosis is simply a connection) a nerve study is one part of the diagnosis of carpal tunnel. Clinicla findings are just as important. If not more so.

carpal tunnel syndr: Increase latency and a median nerve conduction is an indication of carpal tunnel syndrome if that latency occurs at the wrist. Martin gruber is not a syndrome but rather a variation of nerve connections.
