Borders of the cubital tunnel

What are the borders of the cubital tunnel?

The cubital tunnel is the channel through which the ulnar nerve passes at the elbow between the medial epicondyle and the olecranon. The roof of the cubital tunnel is formed by the cubital tunnel retinaculum, normally a thin fibrous structure that extends from the olecranon to the medial epicondyle. The floor of the cubital tunnel is comprised of the elbow capsule and the posterior bundle and oblique band of the UCL.
