The superior extensor retinaculum of the foot (transverse crural ligament) is the upper part of the extensor retinaculum of foot which extends from the ankle to the heelbone. The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on ...
The extensor retinaculum (dorsal carpal ligament, or posterior annular ligament) is a thickened portion of the antebrachial fascia that holds the tendons of the extensor muscles in place. [1] It is located on the back of the forearm, just proximal to the hand. [2] It is continuous with the palmar carpal ligament (which is located on the ...
Extensor tendon compartments of the wrist are anatomical tunnels on the back of the wrist that contain tendons of muscles that extend (as opposed to flex) the wrist and the digits (fingers and thumb). The extensor tendons are held in place by the extensor retinaculum. As the tendons travel over the posterior (back) aspect of the wrist they are ...
The suprascapular, axillary, and radial nerves. The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb. It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and ...
A retinaculum (pl.: retinacula) is a band of thickened deep fascia around tendons that holds them in place. [1] It is not part of any muscle. Its function is mostly to stabilize a tendon. The term retinaculum is Neo-Latin, [2] derived from the Latin verb retinere (to retain). Specific retinacula include:
The muscle passes downward and ends in a tendon that passes under the superior extensor retinaculum and the inferior extensor retinaculum of the foot in the same canal as the extensor digitorum longus muscle. [1] It may be mistaken as a fifth tendon of the extensor digitorum longus. [1]
The palmar carpal ligament (also volar carpal ligament or Guyon's Tunnel) is a thickened portion of antebrachial fascia on anterior/palmar side of the wrist which - together with the flexor retinaculum of the hand - retains the tendons of most of the flexor muscles of the hand. [1]: 215. The PCL is not officially recognised in the Terminologia ...
Technique for transferring the m. extensor carpi radialis longus: the m. extensor carpi radialis longus tendon is divided at its insertion on the second metacarpal. The muscle is separated, and freed entirely from the surrounding tissues. The m. extensor carpi radialis longus tendon is strongly attached to the planned tendon under maximum tension.
