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.
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.
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.
Repetitive Pitching Decreases the Elbow Valgus Stability Provided by the Flexor-Pronator Mass: The Effects of Repetitive Pitching on Elbow Valgus Stability
Baseball pitching induces a large elbow valgus load, stressing the ulnar collateral ligament. Flexor-pronator mass contraction contributes to valgus stability; however, repetitive baseball pitching may weaken the flexor-pronator mass contractile function. The present study investigated the effects of repetitive baseball pitching on the medial valgus stability measured using ultrasonography.
