Load-deformation characteristics of cadaver patellae: Relationship to intraosseous pressure.

Background: Anterior knee pain can arise from several sources. One of the main sources of pain in patients with anterior knee pain is the patella. Increased patellofemoral joint loading is the prime source of patellar pain.

Quantitative Assessment of Balance for Accurate Prediction of Return to Sport From Sport-Related Concussion.

Background: Determining when athletes are able to return to sport after sports-related concussion (SRC) can be difficult.

Hypothesis: A multimodal algorithm using cognitive testing, postural stability, and clinical assessment can predict return to sports after SRC.

Study Design: Prospective cohort.

Concussion-Reporting Behavior in Rugby: A National Survey of Rugby Union Players in the United States.

Background: Rugby is the fastest growing team sport in the United States for male and female athletes. It is a contact/collision sport with an injury risk profile that includes concussions.

Purpose: To examine the prevalence of concussions in male and female rugby players in the United States and to characterize behaviors around reporting concussions that could be a target for prevention and treatment efforts.

Future Directions in Sports-Related Concussion Management.

This article focuses on 3 concepts that continue to be investigated in the search for the holy grail of concussion-a valid diagnostic test. Imaging advances are discussed with optimism that functional MRI and diffusion tensor imaging may be available clinically. Biomarkers and the use of genetic tests are covered.

Consensus on a video analysis framework of descriptors and definitions by the Rugby Union Video Analysis Consensus group.

Using an expert consensus-based approach, a rugby union Video Analysis Consensus (RUVAC) group was formed to develop a framework for video analysis research in rugby union. The aim of the framework is to improve the consistency of video analysis work in rugby union and help enhance the overall quality of future research in the sport. To reach consensus, a systematic review and Delphi method study design was used.

Telephone announcements encouraging common cold self-management reduce demand for general practice appointments.

Background: Patients consulting with the common cold contribute to seasonal demand for general practice appointments. Seeing a community pharmacist or using self-management may have been more appropriate options. The study aimed to measure if the use of telephone announcements signposting appropriate patients with the common cold in the direction of community pharmacy or self-management reduced demand for general practice consultations.

Concussion risk factors and strategies for prevention.

Concussion in children is frequently related to participation in sports. It requires a traumatic event to occur that transmits acceleration to the brain. Some children may have intrinsic risk factors that place them at greater risk for this type of injury.

Return to play after liver and spleen trauma.

Context: Sport-related spleen and liver injuries pose a challenge for the physician. Although rare, these injuries can have serious and even life-threatening outcomes if not accurately diagnosed and managed in a timely fashion. Currently, there are no evidence-based guidelines on duration and intensity of restricted activity and return to play after spleen and liver injury.

Neck strength imbalance correlates with increased head acceleration in soccer heading.

Background: Soccer heading is using the head to directly contact the ball, often to advance the ball down the field or score. It is a skill fundamental to the game, yet it has come under scrutiny. Repeated subclinical effects of heading may compound over time, resulting in neurologic deficits.

Closed head injury.

Closed head injuries vary from the very minor to the catastrophic. It is often difficult to differentiate the severity at initial presentation. Serial assessment is very valuable.

Blunt bladder injury.

Bladder injury should be suspected when trauma is followed by gross hematuria, suprapubic or abdominal pain, and difficulty in voiding or the inability to void. Bladder rupture with blunt abdominal trauma is uncommon; however, because of its high mortality rate, recognition of the early signs and symptoms can be life saving. The most common type of injury is a bladder contusion, which is a diagnosis of exclusion.
