Charcot-Marie-Tooth Disease is a family of inherited disorders of the peripheral nervous system, affecting approximately one in 2,500 Americans. Its most common iteration, CMT1, comes in many forms, most of which have to date been linked to a small set of causative genes. New research recently uncovered a new genetic cause of CMT1.

A torn ACL (also known as the anterior cruciate ligament) is one of the most common knee injuries, with as many as 200,000 cases per year in the U.S. Young people under the age of 20 are at particular risk, in part because of participation in sports.

Men have many reasons to add high-impact and resistance training to their exercise regimens; these reasons include building muscle and shedding fat. Now a researcher has determined another significant benefit to these activities: building bone mass. The study found that individuals who continuously participated in high-impact activities, such as jogging and tennis, during adolescence and young adulthood, had greater hip and lumbar spine bone mineral density than those who did not.

What causes hip dysplasia in adults, and can it be treated without a total hip replacement?.
Patients who received a newer prosthesis similar to the Miller-Galante knee design showed significantly better Knee Society function scores than patients who had a long-used prosthesis to which it was compared. However, the two implants performed about the same at short-term follow-up, according to a presenter.
Posterior shoulder dislocation is rare, and in most cases, it occurs secondary to violent trauma, seizures, or electric shock.1 Approximately 50% of these dislocations are associated with reverse Hill-Sachs lesions.2 Hill and Sachs3 described the lesion in an anterior shoulder dislocation caused by engagement of the humeral head into the glenoid edge and located posterosuperiorly in the head.
Rates of Complications and Secondary Surgeries After In Situ Cubital Tunnel Release Compared With Ulnar Nerve Transposition: A Retrospective Review
The short-term complication rates of cubital tunnel surgery are low (3.2%), but higher for patients with chronic kidney disease. The secondary surgery rate after cubital tunnel surgery was 5.7% overall, but higher for patients with prior elbow trauma and for patients undergoing ulnar nerve transposition.
Shoulder complaints are common in the overhead athlete. Understanding the biomechanics of throwing and swimming requires understanding the importance of maintaining the glenohumeral relationship of the shoulder.
Investigators found significant improvements from preoperative measures at 24.8-month follow-up for both mean side-to-side differences and Lysholm scores in patients who underwent double-bundle ACL reconstruction using a special drill pin guide and reamer, along with a laser-guided device to facilitate a transtibial approach.
