Capitulum of Humerus

The structure indicated is the capitulum of the distal humerus.

The distal end of the humerus consists of several features:

• Condyle, consisting of the capitulum and trochlea
• Medial and lateral epicondyles
• Medial and lateral supracondylar ridges
• Radial fossa, coronoid fossa, olecranon fossa

A large central condyle which has two articular components – the capitulum which articulates with the head of the radius, and the trochlea which articulates with the ulna. Either side of the humeral condyle, are two epicondyles, the medial and lateral epicondyles superior to which are the medial and lateral supracondylar ridges.
