Treatment of Valgus Extension Overload

Valgus extension overload (VEO) can cause significant morbidity in the throwing athlete. VEO results from repetitive extreme valgus forces across the elbow and comprises a constellation of injuries located at the posteromedial compartment (osteophyte formation, olecranon stress fractures, and impingement), the ulnar collateral ligament (UCL), and the radiocapitellar joint (lateral compartment chondrosis). The following chapter provides an overview of the relevant anatomy, biomechanics, and diagnosis of VEO. It further details the arthroscopic surgical technique to successfully treat patients with VEO.
