Clinically Relevant Anatomy[edit | edit source]
The ulna collateral ligament (UCL) consists of three bundles - the anterior oblique ligament/bundle (AOL), the posterior oblique ligament/bundle (POL) and the transverse ligament (which unites AOL and POL)[1][2]. Of the three bundles, the AOL is the strongest and provides significant restraint to valgus force when the elbow is between 30 and 120 degrees flexion. The UCL originates at the anterior-inferior aspect of the medial epicondyle of the humerus and it inserts at the sublime tubercle (the proximal aspect of the ulna)[1][2] . Its main functions are to stabilise the elbow joint and to resist valgus loads[1].
The UCL stabilises the elbow joint by slowing down elbow extension during throwing's deceleration phase and by generating a varus torque, counterbalancing the valgus force[1].
