Background: The rates of ulnar collateral ligament injury and surgery continue to rise in baseball. Increased ball velocity and elbow varus torque may correlate with the increased risk of injury. Hypothesis: Increased ball weight and/or size correlate with decreased elbow varus torque during pitching.

In recent years, innovation in arthroscopic glenoid labral repair techniques has included the development of all- suture anchors. There are multiple potential advantages of all-suture anchors, including decreased bone removal, anchor migra- tion, synovitis/chondral injury, and bone reaction. Despite these potential advantages, few studies have examined clinical out- comes of glenoid labral repair with all-suture anchors.

Background: The ulnar collateral ligament (UCL) of the elbow is commonly injured in baseball athletes. When assessed in the supine abducted and externally rotated (ABER) position using stress ultrasonography (sUS), even before applying a valgus load, gravity pulls on the forearm, creating an initial valgus load that may distort the resting joint space measurement. Purpose/Hypothesis: The purpose of this study was to measure the valgus stress effect of gravity on the resting joint space and determine if a varus-stressed joint space provides a better baseline measurement. It was hypothesized that there would be a greater resting joint space in the throwing arm in the ABER position as a result of UCL laxity but no difference in joint space under varus stress compared to the nonthrowing arm.
