Carpal Tunnel
Anatomical Snuff Box
Distal to the styloid process of the radius at the base of the thumb, the tendons of the abductor pollicis longus, extensor pollicis brevis and extensor pollicis longus form a triangular interval
Has its own tunnel within the lateral attachment of the flexor retinaculum. It DOES NOT pass through the carpal tunnel
Flexor Carpi Radialis
Structures passing through the Carpal Tunnel
Flexor Pollicis Longus, Flexor Digitorum Superficialis & Profundus and Median Nerve
Encases forearm muscle tendons as they descend through the wrist and into the hand and digits
Tubular Synovial Sheaths
A Common Sheath encloses all the Superficialis and Profundus Tendons
Ulnar Bursa
Decrease in size of the carpal tunnel resulting in compression of the median nerve
Carpal Tunnel Syndrome Incision of the flexor retinaculum may palliate
The tendon of Flexor Carpi Radialis
Has a short sheath
Structures Anterior to Carpal Tunnel
Palmaris Longus, Flexor Carpi Ulnaris and Ulnar Nerve & Artery
A sheath surrounds the tendon of the Flexor Pollicis Longus
Radial Bursa
