was changed:
The flexor retinaculum (a.k.a.(also known as the transverse carpal ligament) is a rectangular-shaped fibrous band located at the ventral aspect of the wrist.
Gross anatomy
On the radial side, it attaches to the scaphoid tubercle and the ridge of the trapezium. On the ulnar side, it attaches to the pisiform and the hook of the hamate.
The flexor retinaculum encloses and forms the roof of the carpal tunnel. The ulna aspect of the flexor retinaculum forms the floor of Guyon's canal.
Attachments
- proximally: deep fascia of the forearm
- distally: palmar aponeurosis
Relations
- inferiorly: contents of the carpal tunnel
- superiorly: 3
- ulnar artery and nerve (in Guyon's canal)
- palmar cutaneous branch of the median and ulnar nerves
- palmaris longus tendon
- superficial palmar branch of the radial artery
Variant anatomy
- radial aspect of the flexor retinaculum may be pierced by the median nerve 2
