Nonunion of olecranon stress fractures in adolescent baseball pitchers: a case series of 5 athletes.

Background: Adolescent athletes participating in overhead throwing sports suffer a variety of overuse elbow injuries, many of which have been well described in the literature. Nonunion stress fractures of the olecranon across the epiphyseal plate, however, have received little attention.

Purpose: To describe this unusual clinical entity in the differential diagnosis of the adolescent athlete with elbow pain and to demonstrate that operative treatment is an effective means of quickly and safely returning the patient to sporting activities.

Potential risk of rerupture in primary achilles tendon repair in athletes younger than 30 years of age.

Background: Complete Achilles tendon ruptures are found more often in athletes who participate in sports involving explosive acceleration or maximal effort. In most studies, the consensus for athletes is surgery. This form of treatment has been shown to exhibit the best functional performance with a lower rerupture rate.
