Radial Fossa

The Radial Fossa is a small, shallow depression found on the anterior side of the humerus, the long bone in the upper arm or forelimb that runs from the shoulder to the elbow. It is located just above the elbow joint and is most visible when the elbow is flexed.

Etymology[edit | edit source]

The term "Radial Fossa" is derived from the Latin word "radius" meaning spoke of a wheel, ray, and the Latin word "fossa" meaning ditch or trench.

Anatomy[edit | edit source]

The Radial Fossa is designed to accommodate the head of the radius (one of the two large bones of the forearm) when the elbow is fully bent. It is bordered by the lateral epicondyle of the humerus on one side and the capitulum of the humerus on the other.

Clinical Significance[edit | edit source]

Injuries or abnormalities of the Radial Fossa can impact the full range of motion of the elbow. For example, a fracture in the area of the Radial Fossa can lead to elbow joint instability or stiffness.
