The posterior ligament is thin and membranous and consists of transverse and oblique fibers. Above it is attached to the humerus immediately behind the capitulum and close to the medial margin of the trochlea to the margins of the olecranon fossa and to the back of the lateral epicondyle some little distance from the trochlea. Below it is fixed to the upper and lateral margins of the olecranon to the posterior part of the annular ligament and to the ulna behind the radial notch.
