Paget-Schroetter syndrome (PSS) is thrombosis of the deep veins draining the upper extremity due to anatomic abnormalities of the thoracic outlet that cause subclavian compression and subsequent thrombosis, leading to thrombus formation in the subclavian vein. Vigorous arm activity in sports is a known risk factor. Here, we report a case of Paget-Schroetter syndrome in a 31-year-old male non-professional baseball pitcher.

The quest to identify injury risk factors in sports has been an ongoing and well-researched field in the world of sports medicine. Knowing some of these factors helps keep sports participation safe. Both intrinsic and extrinsic factors have been studied. Body mass index (BMI) is widely known to contribute to several medical conditions. Its association with some sports injuries has been established but the information is vast, with few studies that are randomized controlled trials. It is important to analyze these studies and confirm whether BMI is a predictor of lower-extremity injuries...

Tibial stress fractures are associated with increased lower extremity loading at initial foot-ground contact, reflected in high peak positive acceleration (>8g) of the tibia in adults. There is no reported data on peak positive acceleration of the tibia in children during walking and running. The aim of this study was to establish tibial peak positive acceleration responses in children across a range of age and gait speeds. Twenty-four children aged 8.5±1.4years with no known gait pathology comprised two age groups; Young (7-9year, n=12) and Older (10-12 years, n=12)...

BACKGROUND: Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries. METHODS: A 24-question online survey was distributed to rock climbers about upper extremity injuries sustained during rock climbing...

The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is rarely performed in isolation. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical, because preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated with arthrodesis of the naviculocuneiform or first tarsometatarsal joints...

Many field sports involve equipment that restricts one or both arms from moving while running. Arm swing during running has been examined from a biomechanical and physiologic perspective but not from an injury perspective. Moreover, only bilateral arm swing suppression has been studied with respect to running. The purpose of this study was to determine the influence of running with one arm restrained on lower extremity mechanics associated with running or sport-related injury. Fifteen healthy participants ran at a self-selected speed with typical arm swing, with one arm restrained and with both arms restrained...

BACKGROUND: High school athletes are increasingly encouraged to participate in 1 sport year-round to increase their sport skills. However, no study has examined the association of competition volume, club sport participation, and sport specialization with sex and lower extremity injury (LEI) in a large sample of high school athletes. HYPOTHESIS: Increased competition volume, participating on a club team outside of school sports, and high levels of specialization will all be associated with a history of LEI...

The war on drugs is usually associated with criminal policies aimed at stemming consumption of drugs such as heroin, cocaine, and cannabis, less so with enhancement drugs like those used in sport. As drug use in sport, or doping, has become more visibly widespread, policies aimed at combating the issue have become more restrictive, intrusive, and harsh. In this article we draw new comparisons between the wider war on drugs and recent developments in sports anti-doping. We identify a growing trend towards criminalisation of traffickers and users, and associate that with another growing trend: the testing of amateur athletes...

CONTEXT: Deficits in ankle and hip strength and lower extremity postural control are associated with chronic ankle instability (CAI). Following strength training, muscle groups demonstrate increased strength. This change is partially credited to improved neuromuscular control and many studies have investigated ankle protocols for subjects with CAI. The effects of isolating hip musculature in strength training protocols in this population is not well understood. OBJECTIVE: Examine the effects of hip strengthening on clinical and self-reported outcomes in patients with CAI...
