The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles.
The common extensor tendon is a tendon that attaches to the lateral epicondyle of the humerus. Structure ... The common extensor tendon is the major attachment point ...
the lateral ulnar collateral ligament (LUCL), from the lateral epicondyle [3] to the supinator crest on the ulna. Near the attachment on the humerus this ligament is normally indistinguishable from the RCL and can be considered the posterior portion of it. [1]
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]
The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm ; [ 2 ] more specifically between the humerus in the upper arm and the radius and ulna in the ...
The extensor digitorum muscle arises from the lateral epicondyle of the humerus, by the common tendon; from the intermuscular septa between it and the adjacent muscles, and from the antebrachial fascia.
The extensor carpi radialis longus is one of the five main muscles that control movements at the wrist. [1] This muscle is quite long, starting on the lateral side of the humerus, and attaching to the base of the second metacarpal bone (metacarpal of the index finger).
Epicondyles are on the medial and lateral aspects of the elbow, consisting of the two bony prominences at the distal end of the humerus. These bony projections serve as the attachment point for the forearm musculature. [2] Inflammation to the tendons and muscles at these attachment points can lead to medial and/or lateral epicondylitis.
