Preseason shoulder strength measurements in professional baseball pitchers: identifying players at risk for injury.

Background: The ability to identify pitchers at risk for injury could be valuable to a professional baseball organization. To our knowledge, there have been no prior studies examining the predictive value of preseason strength measurements.

Hypothesis: Preseason weakness of shoulder external rotators is associated with increased risk of in-season throwing-related injury in professional baseball pitchers.

Arthroscopic distal clavicle resection in athletes: a prospective comparison of the direct and indirect approach.

Background: The clinical success of arthroscopic distal clavicle resection for athletes has been well documented. There are, however, no published studies that prospectively compare the recovery rates in athletes as well as the outcomes of the indirect versus direct approaches.

Hypothesis: Both procedures are equally successful; however, the direct approach affords faster return to sports.
