Osteochondritis dissecans of the knee: What to know
Osteochondritis dissecans of the knee may not cause any symptoms, but some people may experience pain and swelling. Engaging in competitive sports may contribute to its development.
Impact of Reverse Shoulder Arthroplasty Design and Patient Shoulder Size on Moment Arms and Muscle Fiber Lengths in Shoulder Abductors
Reverse shoulder arthroplasty (RSA) increases the moment arm of the deltoid, however there is limited knowledge on the accompanying changes in muscle architecture that play a role in muscle force production. The purpose of our study is to use a geometric shoulder model to evaluate the anterior deltoid, middle deltoid, and supraspinatus regarding 1) differences in moment arms and muscle-tendon lengths in small, medium, and large native shoulders, and 2) impact of three RSA designs on moment arms, muscle fiber lengths, and force-length (F-L) curves.
Predicting the need for collateral ligament repair in transolecranon fractures of the elbow: a traffic light model
Biomechanical studies have shown translation of the proximal radius relative to the capitellum in the sagittal plane can predict integrity of the collateral ligaments in a transolecranon fracture model; no studies have examined this in clinical practice.
Headaches after exercise: Here's why they happen—and how to prevent them
For some people, going for a run can trigger what's known as a "runner's high," a short-lasting feeling of euphoria or relaxation. But for others, running can trigger something far less pleasant: a headache.
Chondromalica: Causes, Risk Factors, and Prevention
Chondromalacia patella, also known as runner's knee, is a knee condition that can cause pain and grinding when the knee is flexed. It's due to the breakdown in the cartilage on the undersurface of the kneecap (patella) that causes bones to rub against each other. Overuse (especially from running or cycling), trauma, such as a fracture, or a misalignment of the kneecap and femur can all cause chondromalacia.
