Background: Because of the high risk for redislocations after a first-time traumatic anterior shoulder dislocation with conservative treatment, recent publications have recommended early arthroscopic intervention, especially for young athletes. Concomitant rotator cuff tendon damage may occur when the shoulder dislocates; however, its presence and influence on clinical results have not been well described in this patient category. Hypothesis: In opposition to current opinion, a substantial number of articular-sided partial-thickness rotator cuff tears (APTRCTs) would be found at surgery after a first-time traumatic anterior shoulder dislocation in young athletes...

Background: Medial meniscal tears are commonly seen during anterior cruciate ligament reconstruction (ACLR). A subset of these injuries includes posterior meniscocapsular junction or "ramp" tears. One criterion that may correlate with a ramp lesion is the presence of posterior medial tibial plateau (PMTP) edema. Purpose: To compare patients with ramp lesions to patients with nonramp (meniscal body) medial meniscal tears and correlate PMTP edema on preoperative magnetic resonance imaging (MRI) to the incidence of ramp tears...

BACKGROUND: Neurogenic thoracic outlet syndrome (NTOS) is the most common form of TOS and may occur from injury, occupational stress or athletic endeavors. While most patients with NTOS will improve after first rib resection and scalenectomy (FRRS), the prognostic risk factors for success remain unclear. Athletes are a very motivated and disciplined demographic and therefore should be a group more likely to respond to FRRS for NTOS than non-athletes. We hypothesized that athletes would do better after FRRS than non-athletes despite the added physical stress that sporting activity imposes...

A 71-year-old woman with a 10-month history of atraumatic low back pain was referred to physical therapy after an insidious exacerbation of symptoms. Red flags raised suspicions for spinal compression fracture, necessitating the physical therapist to contact her physician and recommend imaging. Radiographs and magnetic resonance imaging were ordered, the latter of which showed an acute fracture at T10, with lesions at T9 and in the liver suggesting metastasis. Following bone scintigraphy and an ultrasound-guided biopsy of a liver lesion, she was diagnosed with metastatic breast cancer...

To succeed at a sport, athletes must manage the biomechanical trade-offs that constrain their performance. Here, we investigate a previously unknown trade-off in soccer: how the speed of a kick makes the outcome more predictable to an opponent. For this analysis, we focused on penalty kicks to build on previous models of factors that influence scoring. More than 700 participants completed an online survey, watching videos of penalty shots from the perspective of a goalkeeper. Participants (ranging in soccer playing experience from never played to professional) watched 60 penalty kicks, each of which was occluded at a particular moment (-0...

PRIMARY OBJECTIVE: Closed brain injuries are a common danger in contact sports and motorized vehicular collisions. Mild closed brain injuries, such as concussions, are not easily visualized by computed imaging or scans. Having a comprehensive head/brain model and using fluid-structure interaction (FSI) simulations enable us to see the exact movement of the cerebrospinal fluid (CSF) under such conditions and to identify the areas of brain most affected. RESEARCH DESIGN: The presented work is based on the first FSI model capable of simulating the interaction between the CSF flow and brain...

Having ostomy surgery changes a person's life. To assess adjustment to life with an ostomy and quality of life (QOL) 1 year after ostomy surgery, a prospective, explorative study was conducted among patients of a stoma clinic at a university hospital in Sweden. All consecutive patients who had undergone nonemergent or emergency surgery involving formation of an ostomy and who received regular follow-up at the ward and at the outpatient clinic during the first year by an enterostomal therapist (ET) were prospectively included in the study; their demographic information (including age, gender, diagnosis/reason for an ostomy, nonemergent or emergency surgery, ostomy type, preoperative counselling/siting [Yes/No], self-sufficiency in stoma care, professional activity, and whether they lived with a spouse/partner) was recorded upon admission to the study...

Objectives: Lower limb isometric tests are used to assess strength and strength asymmetries and monitor reductions in muscle force that may contribute to loss of performance and increase injury risk. Isometric tests in the upper body may be appropriate to monitor neuromuscular performance of the shoulder joint in sports involving contact and overhead actions. The aim of this study was to determine the reliability of a novel upper body isometric strength test. Methods: Eighteen elite rugby players (age 22...

Practicing sport at the highest level is typically accompanied by several stressors and restrictions on personal life. Elite athletes' lifestyle delivers a significant challenge to sleep, due to both the physiological and psychological demands, and the training and competition schedules. Inter-individual variability of sleep patterns (e.g., sleep requirements, chronotype) may have important implications not only for recovery and training schedules but also for the choice of measures to possibly improve sleep...

BACKGROUND: Despite the risks, concussion symptoms often go underreported by athletes, leading to delayed or forgone treatment and increased potential for concussion recurrence. One of the most serious long-term consequences of sports-related concussions is Chronic Traumatic Encephelopathy (CTE), a disorder associated with progressive neurological deterioration. The purpose of this study was to explore former collegiate athletes' understanding of concussions and motivations behind concussion non-disclosure in order to better assist family medicine providers in screening for and managing a history of concussions...

Traumatic brain injury has been associated with increased risk of Parkinson disease and parkinsonism, and parkinsonism and Lewy body disease (LBD) can occur with chronic traumatic encephalopathy (CTE). To test whether contact sports and CTE are associated with LBD, we compared deceased contact sports athletes (n = 269) to cohorts from the community (n = 164) and the Boston University Alzheimer disease (AD) Center (n = 261). Participants with CTE and LBD were more likely to have β-amyloid deposition, dementia, and parkinsonism than CTE alone (p < 0...

Background and objective The high incidence of traumatic brain injuries during contact sports has necessitated the need for further research pertaining to their implications and possible mitigation. Despite increasing attention to sports-related concussions, there is still a striking lack of detail pertaining to the environmental factors that contribute to their occurrence. One environmental condition that has yet to be considered is altitude. Altitude cannot be readily adjusted, yet can still impact quality of play and concussion incidence...
