Gross anatomy
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.
It has superficial and deep layers, which are separate on the radial aspect, containing the tendon of flexor carpi radialis.
Attachments
proximal: deep fascia of the forearm
distal: palmar aponeurosis
Relations
deep: contents of the carpal tunnel
-
superficial 3
ulnar artery and nerve (in Guyon's canal)
palmar cutaneous branch of the median and ulnar nerves
palmaris longus tendon
origins of thenar and hypothenar muscles
between superficial and deep layers: tendon of flexor carpi radialis

Variant anatomy
radial aspect of the flexor retinaculum may be pierced by the median nerve 2
