The Medial Supracondylar Ridge is a prominent anatomical feature found on the humerus bone in the human body. It is a ridge that runs vertically down the posterior aspect of the distal humerus, serving as an attachment site for various muscles and ligaments.

Anatomy

The Medial Supracondylar Ridge is located on the posterior aspect of the distal humerus, just above the medial epicondyle. It runs parallel to the medial border of the humerus and is more prominent than the lateral supracondylar ridge.

Function

The primary function of the Medial Supracondylar Ridge is to provide an attachment site for muscles and ligaments. Specifically, it serves as the origin for the flexor carpi radialis, pronator teres, and part of the flexor digitorum superficialis muscles.

Clinical Significance

Injuries or abnormalities to the Medial Supracondylar Ridge can impact the function of the muscles attached to it, potentially affecting movement and flexibility in the arm and hand. It may also be a site of interest in orthopedic surgery, particularly in procedures involving the elbow joint.
