Soccer is becoming an increasingly popular sport amongst women. Common movements during play, such as jumping and cutting, require rapid acceleration and deceleration of multiple lower-limb joints. The anterior cruciate ligament (ACL), which contributes to stabilization of the knee, is often injured during these events. ACL injury typically requires costly surgery, extended time away from sports, and jeopardizes long-term joint health. Due to sex-specific factors such as menstruation and anatomical disadvantages, women are more susceptible to tearing their ACL. Injury often occurs in non-contact scenarios during rapid acceleration or deceleration movements. Research has examined these movements and established several kinematic and kinetic mechanisms as well as muscle activation patterns that frequently occur at the time of injury, however results tend to vary based on population. This article summarizes recent and relevant literature of ACL injury mechanisms and highlights the lack of specific research in the high-risk female soccer athlete population. Due to inconclusive risk factors, injury prevention programs within this population have been inconsistent. ACL injury risk for female soccer athletes should be closer examined so that more specific injury risks can be established, and effective protective measures can be taken. Raised awareness of this need may capture attention in the research and medical communities and potentially stimulate the development of strategies that limit future ACL injury and thus the challenges it brings to the high-risk female soccer athlete.
Background: Transolecranon distal humerus fractures are uncommon injuries. The purpose of this study is to review the outcomes and complications associated with transolecranon distal humerus fractures. Material and Methods: We performed a systematic search of PubMed for articles published between 1990 and 2021. Included studies reported outcomes and complications of transolecranon distal humerus fractures. Data was extracted from the included studies to describe patient demographics, injury characteristics, outcome measurements, and complications. Results: A total of 4 studies met inclusion criteria for data extraction and analysis. Two studies evaluated an adult cohort of a total of 18 patients. The average Disabilities of the Arm, Shoulder, and Hand (DASH) score was 40 (range 4.2 – 76.5). Fifteen patients (83%) had a complication. Elbow stiffness (11/18, 61%) was the most common complication. Eleven patients (61%) underwent more than one procedure. Two studies evaluated a pediatric cohort of a total of 9 patients. Five patients (56%) underwent non-operative treatment with immobilization and four patients (44%) underwent open reduction and internal fixation. There were no complications reported. All the pediatric patients regained near full range of motion of the elbow at their final follow-up. Conclusion: Transolecranon distal humerus fractures are complex elbow injuries. In the adult population, they remain a challenge for orthopaedic surgeons. Complications, including elbow stiffness and infection, are high with frequent long-term functional limitations as represented by DASH scores. In contrast, pediatric patients have good outcomes and minimal complications that are similar to isolated olecranon and distal humerus fractures in children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
