Capitulum of the humerus

Capitulum of the Humerus

The Capitulum of the Humerus is a rounded eminence found at the distal end of the humerus. It is a key anatomical structure in the elbow joint, articulating with the radius in the forearm.

Etymology

The term "capitulum" is derived from the Latin word "caput", meaning "head". This is in reference to the head-like shape of the capitulum.

Anatomy

The capitulum of the humerus is located on the anterior surface of the distal end of the humerus. It is lateral to the trochlea and is spherical in shape. The capitulum articulates with the head of the radius, forming part of the elbow joint.

Clinical Significance

Injuries to the capitulum can result in elbow joint instability and loss of function. Fractures of the capitulum are relatively rare but can occur as a result of direct trauma or a fall onto an outstretched hand. Treatment typically involves surgical intervention to restore the normal anatomy and function of the elbow joint.
