Charcot-Marie-Tooth Disease (CMT) 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 from the department of Neurology at the Perelman School of Medicine at the University of Pennsylvania and the Children’s Hospital of Philadelphia recently spanned the globe to uncover a new genetic cause of CMT1. Their findings are published online this week in Brain.
Titled “Prevalence of Sport Specialization in High School Athletics,” this one-year observational study found that high school athletes from a smaller school were less likely to specialize in a sport than those attending a large school. The researchers also found that highly specialized athletes were more likely to report a history of overuse knee or hip injuries.
Calcific tendinitis of the shoulder, typically characterized by calcium deposits on the rotator cuff, is an extremely painful condition that can severely impair movement and life quality. A new study appearing in today’s issue of the Journal of Bone and Joint Surgery, found a significant increase in blood vessel and pain receptor growth among patients with this condition.
Results from this prospective, cross-sectional study demonstrated catastrophic thinking and lower self-efficacy were linked with more shoulder pain and disability among patients who presented with shoulder pain and had no history of shoulder surgery.
AFL, basketball and netball players are the major sufferers, with tendon pain in the knee debilitating and long-lasting. The injury can sideline a player or cause them to give up the sport entirely.
Recently published data indicated performance and return to play among Major League Baseball players after revision Tommy John surgery decreased, specifically with regard to durability, compared with matched controls.
Despite increasing medical knowledge, treating shoulder pain in baseball pitchers and other throwing athletes remains one of the most challenging tasks in sports medicine.
Although a survey of patients who underwent arthroscopic Bankart repair for the treatment of chronic shoulder instability showed all patients who were active in sports preoperatively returned to sport postoperatively, 26% of patients reported no benefits in sporting activity after the surgery.
Researchers of this study note that although the open Latarjet procedure provided significant improvement in clinical scores for patients with anterior shoulder instability and glenoid bone loss, 90.5% of patients showed graft resorption on CT at 1-year postoperatively.
Specialization in youth sports has led to an increased number of overuse injuries in young athletes, often amounting to acute injuries or withdrawal from play, according to prominent sports medicine physicians who spoke with Orthopedics Today.
Posterior glenohumeral instability is rare, accounting for approximately 5% of cases of shoulder instability. Although bone loss is implicated in most cases of recurrent anterior glenohumeral instability, the impact of glenoid bone loss on posterior instability is poorly understood. Specifically, the quantity of posterior glenoid bone loss that would prohibit the success of a posterior soft tissue stabilization procedure alone for recurrent posterior instability is unknown.
CHICAGO — The pooled rate of return to play following lumbar microdiscectomy for herniated disc nucleus was 83.5%, according to results presented at the North American Spine Society Annual Meeting, and the overall return to play rate for elite athletes with a herniated disc after this procedure was 84.5%.
In a pre- and post-season ultrasound evaluation of high school pitchers’ elbows, adaptive changes occurred to multiple structures about the elbow from stresses placed on the elbow during one season of pitching, based on results of a recently published study.
Motion Created in an Unstable Cervical Spine During the Removal of a Football Helmet: Comparison of Techniques
Helmet removal is necessary to maintain airway access in a suspected cervical spine injury. The aim of this investigation was to determine which of two football helmet removal techniques minimized angular and translational displacement in a suspected cervical injury.
Although investigators of this study found a combination of Bankart repair and Bristow procedure prevented recurrent shoulder dislocation in rugby players, some patients complained of insufficiency in quality of their play when performing specific movements.
Researchers observed an increase in the incidence of ulnar collateral ligament reconstruction among young athletes between the ages of 15 and 19 years old, according to study results.
Contrary to popular belief, the worst injuries baseball catchers face on the field come from errant bats and foul balls, not home-plate collisions with base runners, according to findings of a study led by researchers at the Johns Hopkins University School of Medicine.
