Epicondyle: Anatomy, Function, and Common Injuries

epicondyle

raised area on or above a condyle

Epicondyle refers to a prominent projection or bump on a bone that serves as an attachment point for muscles, tendons, or ligaments. There are two main epicondyles on the humerus bone in the upper arm: the medial epicondyle and the lateral epicondyle.

The medial epicondyle is located on the inside of the elbow and serves as the site of attachment for several muscles that control movement of the wrist and hand. These muscles include the flexor carpi radialis, flexor carpi ulnaris, and pronator teres.

The lateral epicondyle is located on the outer side of the elbow and serves as the site of attachment for several muscles that control movement of the wrist and hand as well as the forearm. These muscles include the extensor carpi radialis brevis, extensor digitorum, and supinator.

Injuries to the epicondyle can occur due to trauma or repetitive strain, which can cause pain and weakness in the affected area. Treatment options may include rest, ice, compression, and physical therapy to promote healing and restore function.
