Valgus extension overload syndrome in adolescent baseball players: clinical characteristics and surgical outcomes

Background Little is known about the clinical characteristics and surgical outcomes of valgus extension overload syndrome (VEOS) in adolescent athletes.

Description
Summary:Background Little is known about the clinical characteristics and surgical outcomes of valgus extension overload syndrome (VEOS) in adolescent athletes. We evaluated posteromedial compartment pathology, including combined lesions, and reported the surgical outcomes in adolescent baseball players. Methods We retrospectively reviewed the medical records of 13 male adolescent baseball players (mean age, 15.4 years) who underwent arthroscopic olecranon tip resection (n = 9) or staged operations (arthroscopic olecranon tip resection, followed by medial collateral ligament reconstruction 2 weeks later; n = 4). The shape of the tip fragment was used to classify the olecranon into 2 types: type 1, dot-like fragment (n = 3); type 2, triangular-shape fragment (n = 10). Four outcome measures were analyzed: range of motion, visual analog scale (VAS) pain score, rate of return to play, and Conway scale score. Results At a mean follow-up of 3.3 years (range, 2-6 years), the mean VAS pain score decreased from 4.1 preoperatively to 1.1 postoperatively ( P
