Approach to Medial Elbow Pain in the Throwing Athlete.

Abstract

Injury to the ulnar collateral ligament is the most common, significant injury affecting the medial elbow of the overhead athlete. However, there are many other significant sources of pathology that should be considered. This review seeks to present a broad range of conditions that providers should consider when evaluating the overhead athlete with medial elbow pain. Recent biomechanical studies have deepened understanding of the anatomy and function of the anterior bundle of the ulnar collateral ligament germane to the overhead athlete. Orthobiologics hold potential for expanding the role of non-operative treatment for ulnar collateral ligament injuries. In addition to injury to the ulnar collateral ligament, providers should be prepared to diagnose and treat valgus extension overload, proximal olecranon stress fracture, ulnar nerve pathology, common flexor - pronator mass injury, and, in adolescents, medial epicondylar avulsion, when managing medial elbow pain in the overhead athlete.
