Biomechanical comparison of ulnar collateral ligament reconstruction techniques.

Background: Incompetence of the ulnar collateral ligament (UCL) of the elbow is career-threatening for high-performance throwing athletes. Although multiple reconstructions have been described, a procedure that combines a larger graft with improved fixation may demonstrate more favorable loading characteristics than current techniques.

Hypothesis: Ulnar collateral ligament reconstructions utilizing a semitendinosus graft and interference knot fixation will be biomechanically superior to previously reported techniques.

Lymphocutaneous nocardiosis from commercially treated lumber: a case report.

Goal: To understand nocardiaI infections to better manage patients with the condition.

Objectives: 1. Identify the organisms causing nocardial infections in humans.
