The Hip: Preservation, Replacement and Revision

Forearm Extensors     


- See: Flexor muscles of the Forearm:

- Superficial muscles arise from a common tendon attached to the lateral epicondyle of the humerus, and divide into lateral and medial groups;
    - Lateral three of these muscles:
            Brachioradialis
            Extensor Carpi Radialis Longus  /  Brevis
    - Medial group:
            Extensor Digitorum  communis
            Extensor Digiti Minimi
            Extensor Carpi Ulnaris
            Anconeus
- Deep muscles on the back of the forearm are:
    - Supinator
    - Abductor Pollicis Longus
    - Extensor Pollicis Longus  /  Brevis
         - latter three muscles to thumb surface in furrow between two groups of superficial muscles;
         - they insert on thumb at base of metacarpal, proximal phalanx, & distal phalanx respectively;

- Extensor Retinaculum:
    - on dorsal side extensor tendons, w/ exception of brachioradialis, pass under an extensor retinaculum that holds them close to bone 
        & maintains their uniform mechanical relationship to the carpus
