Trochlear fovea

Trochlear fovea is a small, shallow depression found on the trochlea of the humerus, a long bone in the upper arm or forelimb that runs from the shoulder to the elbow. It is located on the medial part of the bone, near the elbow joint. The trochlear fovea is an important anatomical feature as it serves as a point of articulation for the ulna, one of the two bones in the forearm.

Etymology

The term "trochlear" is derived from the Latin word "trochlea", which means "pulley". This is in reference to the pulley-like structure of the trochlea of the humerus. The term "fovea" is derived from the Latin word "fovea", which means "pit" or "depression". This is in reference to the small, shallow depression that is the trochlear fovea.

Anatomy

The trochlear fovea is located on the medial part of the humerus, near the elbow joint. It is a small, shallow depression on the trochlea of the humerus. The trochlea is a spool-like structure on the distal end of the humerus that articulates with the ulna. The trochlear fovea serves as a point of articulation for the ulna, allowing for the movement of the forearm.

Clinical Significance

The trochlear fovea is an important anatomical landmark in orthopedic surgery, particularly in procedures involving the elbow joint. Damage to the trochlear fovea can result in reduced range of motion and pain in the elbow joint. In severe cases, surgical intervention may be necessary to repair the damage and restore normal function.
