Daniel M Costello, Joel Ernest, Andrew H Kaye, Terence J O'Brien, Sandy R Shultz
Australian Rules Football is a collision sport that is associated with increased sport-related concussion risk. Sport-related concussion is a common form of mild traumatic brain injury that is now recognised as a serious health issue. This study measured the concussion incidence rate for amateur Australian Rules players over 3 seasons (2015-2017) by athlete exposures-a metric used widely in the literature. This study also reported concussion incidence based on player match hours, a less common yet more accurate method of reporting concussion incidence which takes match duration into account...

PURPOSE: Muscle injury is the most common sports injury. Muscle stiffness, a risk factor for muscle injury, is lower in females than in males, implying that sex-related genetic polymorphisms influence muscle injury associated with muscle stiffness. The present study aimed to clarify the associations between two genetic polymorphisms (rs2234693 and rs9340799) in the estrogen receptor 1 gene (ESR1) and muscle injury or muscle stiffness. METHODS: In study 1, a questionnaire was used to assess the muscle injury history of 1,311 Japanese top-level athletes...

Over-the-counter analgesics, such as anti-inflammatory drugs (NSAIDs) and paracetamol, are widely consumed by athletes worldwide to increase pain tolerance, or dampen pain and reduce inflammation from injuries. Given that these drugs also can modulate tissue protein turnover, it is important to scrutinize the implications of acute and chronic use of these drugs in relation to exercise performance and the development of long-term training adaptations. In this review we aim to provide an overview of the studies investigating the effects of analgesic drugs on exercise performance and training adaptations relevant for athletic development...

Changes of direction (CODs) are key manoeuvres linked to decisive moments in sport and are also key actions associated with lower limb injuries. During sport athletes perform a diverse range of CODs, from various approach velocities and angles, thus the ability to change direction safely and quickly is of great interest. To our knowledge, a comprehensive review examining the influence of angle and velocity on change of direction (COD) biomechanics does not exist. Findings of previous research indicate the biomechanical demands of CODs are 'angle' and 'velocity' dependent and are both critical factors that affect the technical execution of directional changes, deceleration and reacceleration requirements, knee joint loading, and lower limb muscle activity...

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: Arena football is an indoor version of American football played in indoor arenas on a smaller field with 8 players per team. Only 1 study has evaluated injury rates in arena football, and no study had compared 2 distinct cohorts of players. Purpose/Hypothesis: The purpose of this study was to evaluate and compare injury rates in American versus Chinese athletes in the Chinese Arena Football League. Our hypothesis was that the rate of significant injuries (≥7 days of time lost from play) would be statistically significantly higher in Chinese athletes...

Bungee jumping is a recreational sport that is accepted to carry a level of risk. We present the case of a femoral fracture sustained during bungee jumping and examine the published literature on bungee jumping-related injuries. A previously well 31-year old female performed a 200ft bungee jump from a crane. The apparatus was performed as expected and documented on the bystander video footage. As the bungee-cord became taut for the second time, there was an audible crack with accompanying scream. A closed, neurovascularly-intact injury was sustained to her right thigh...

Repetitive overhead throwing generates tremendous demands on the shoulder joint of the overhead athlete. Clinicians, therapists, and medical staff are charged with optimizing a throwing athlete's shoulder mobility and stability to maximize performance and prevent injury. Modifiable risk factors such as strength asymmetry, glenohumeral range of motion deficits, and scapulothoracic joint abnormalities contribute to the overhead athlete's predisposition to shoulder injury. Most shoulder injuries in the overhead thrower can be successfully treated nonoperatively to allow in-season return to sport...

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...

BACKGROUND: Clinical management of sport-related concussion typically involves a symptom checklist, clinical examination of mental status, and neurocognitive testing. However, recent studies have identified unresolved, impaired sensorimotor function after athletes return to sport. A review and meta-analysis of all current literature regarding risk of subsequent musculoskeletal (MSK) injury after concussion has yet to be published in the medical literature. Purpose/Hypothesis: To determine the odds that athletes will sustain MSK injury after concussion...

BACKGROUND: Specific training reduces the risk of falls and fall-related injuries in older persons. The availability of specific exercise programs in Germany, especially in rural areas is scarce. Therefore, a healthcare fund driven program osteoporotic fracture prevention program in rural areas (OFRA) (German name: "Trittsicher durchs Leben") was implemented in rural areas in 47 counties of 5 federal states. The most important components of the program are the "Trittsicher" mobility course and falls prevention classes organized by members of the German Association of Rural Women and executed by exercise instructors of the German Gymnastics Association or physiotherapists...

Females are well known to have a two to nine times increase in relative risk of anterior cruciate ligament (ACL) rupture as compared with males. However, there is limited literature available regarding the rates of associated intra-articular and extra-articular injuries associated with ACL ruptures. The purpose of this study was to investigate the gender differences in intra-articular and extra-articular injuries associated with ACL ruptures in an acute setting. Therefore, in the cross-sectional study of consecutive patients, all patients who underwent ACL reconstruction in a single institution were identified if they had a magnetic resonance imaging (MRI) done within 6 weeks of sustaining the injury and if their injury was sustained during sports activities...

INTRODUCTION: Regardless of the good outcomes of conservatively treated fingertip injuries, many patients complain about volume defects and hypoesthesia. Injection of autologous fat into the defect zone may resolve the volume problem and stimulate digital nerve regeneration by adipose derived stem cell transplantation. METHODS: We analyzed 5 volume defects resulting from conservatively treated fingertip injuries in 4 patients (male to female ratio, 2:2), 6 months after the injection of autologous abdominal fat into the defect zone retrospectively...
