flex·or ret·i·nac·u·lum of hand

[TA]
a strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel.

In the group of patients with diabetes, the average cross-sectional area of the median nerve was measured as 10.2[+ or -]2.9 [mm.sup.2] in the proximal region, 7.5[+ or -]1.9 [mm.sup.2] beneath, and 7.7[+ or -]1.8 [mm.sup.2] in the distal region of the transverse carpal ligament. In the control group, the average cross-sectional area of the median nerve was 10.2[+ or -]2.5 [mm.sup.2] in the proximal region, 6.9[+ or -]1.3 [mm.sup.2] beneath, and 6.6[+ or -]1.4 [mm.sup.2] in the distal region of the transverse carpal ligament.

The back wall of the carpal tunnel is bound by the carpal bones and a band of strong tissue called transverse carpal ligament. Passing through the carpal tunnel are several structures - the various tendons which help in the movement of fingers, the (median) nerve which supplies half the palm and thumb and index finger, and branches of arteries that supply these structures.
The carpal tunnel is a space located posteriorly between the carpal bones of the wrist (moving from fight to left: trapezium, trapezoid, capitate, and hamate), forming the hard "carpal floor," and anteriorly, where the transverse carpal ligament forms a fibrous sheath or the "carpal roof" (see Fig 1).
The flexor retinaculum or transverse carpal ligament forms the roof of the canal through which the median nerve and the long flexor tendons pass.
