Medial epicondyle

Medial Epicondyle

The Medial Epicondyle is a prominent bony structure located on the inner side of the elbow, which is part of the humerus bone. It serves as an attachment site for several important muscles and ligaments that function in the movement and stability of the forearm and hand.

Anatomy

The Medial Epicondyle is situated at the distal end of the humerus, and is larger and more prominent than the lateral epicondyle. It is the point of origin for several muscles, including the pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, and flexor digitorum superficialis. These muscles are primarily involved in the flexion and pronation of the forearm and hand.

Clinical Significance

Injuries to the Medial Epicondyle are common, particularly in athletes who perform repetitive throwing or swinging motions, such as baseball players or golfers. This can lead to conditions such as Medial Epicondylitis, also known as Golfer's Elbow, which is characterized by pain and inflammation in the area of the Medial Epicondyle. Treatment typically involves rest, physical therapy, and in some cases, surgery.

In children, a common injury is the Medial Epicondyle Fracture, which occurs when the ligament attached to the Medial Epicondyle is forcefully pulled, causing the epicondyle to fracture. This is often seen in sports that involve throwing, and requires immediate medical attention.
