Isolated traumatic dislocation of the thumb carpometacarpal joint, also called the trapeziometacarpal joint, is a rare injury. Controversy still exists concerning which ligaments are the true key stabilizers for the joint and therefore need to be damaged to result in dislocation, and optimal treatment strategies for thumb carpometacarpal joint dislocations are the subject of continuing debate. We give a review of the literature concerning traumatic dislocations of the carpometacarpal joint of the thumb and propose a treatment algorithm.

Medial collateral ligament injuries are rare and occur almost exclusively in overhand-throwing athletes. The late cocking phase of the overhand throw places a marked valgus moment across the medial elbow. This repetitive force reaches the tensile limits of the medial collateral ligament, subjecting it to microtraumatic injury and attenuation. ⋯ Injury to the medial collateral ligament can be confirmed by physical examination (moving valgus stress test) and appropriate imaging studies (computed tomography arthrogram and magnetic resonance imaging). Reconstructive techniques of the medial collateral ligament have evolved over time and currently provide superior outcomes, with 80% to 90% of athletes returning to the same level of competitive play. As our understanding of the pathoanatomy of medial elbow injuries progresses and newer hybrid techniques evolve, our ability to care for the overhand-throwing athlete can be expected to improve.

To test the null hypothesis that depression does not correlate with patient satisfaction after open release of electrodiagnostically confirmed carpal tunnel syndrome when controlling for other demographic, disease-related, and psychosocial factors. ⋯ Prognostic II.

Although rare, hand injury caused by puncture with the sea urchin spine can result in serious complications. To emphasize its clinical significance, this article describes a group of patients who sustained chronic granulomatous arthritis induced by puncture with sea urchin spine (designated sea urchin spine arthritis). ⋯ Therapeutic IV.
