The extensor carpi radialis longus (ECRL) has the most proximal origin of the extrinsic hand extensors. It originates just distal to the brachioradialis at the lateral supracondylar ridge of the humerus, the lateral intermuscular septum, and by a few fibers at the lateral epicondyle of the humerus. [1]
Juncturae tendinum are narrow bands of connective tissues that extend between the tendons of the extensor digitorum communis and the extensor digiti minimi. [1] [2] It is classified into three distinct types (Type 1, 2 and 3) depending on morphology. [3] Type 1: This is a thin and filamentous juncturae tendinum. Its shape can either be square ...
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 enclosed within synovial tendon sheaths . These sheaths reduce the friction to the extensor tendons as they traverse the compartments that are formed by the attachments of the extensor retinaculum to ...
Mallet finger is acquired due to injury to the thin extensor tendon that functions to straighten the end (DIP) joint of a finger. [8] Jamming of the finger induces a rupture of the extensor tendon or a broken bone at the tendon's site of attachment. [9] This results in a droopy and crooked appearance of the end joint of the finger, resembling a ...
In medicine a Busch fracture [1] is a type of fracture of the base of the distal phalanx of the fingers, produced by the removal of the bone insertion of the extensor tendon. Without the appropriate treatment, the finger becomes a hammer finger. It would correspond to the group B of the Albertoni classification. [2]
Lateral elbow pain can be caused by various pathologies of the common extensor tendon. [3] Overuse injuries can lead to inflammation. [4] [5] Tennis elbow is a common issue with the common extensor tendon. [6] [4] [7]
The extensor digitorum muscle (also known as extensor digitorum communis) [2] is a muscle of the posterior forearm present in humans and other animals. It extends the medial four digits of the hand. Extensor digitorum is innervated by the posterior interosseous nerve, which is a branch of the radial nerve. [3]
Extensor compartments of wrist (back of hand) The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers.
