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.
Swelling, pain and stiffness in the joints are common symptoms for people with arthritis. If you have arthritis, your health care professional may recommend hand exercises to help you improve joint flexibility and range of motion.
The neck and shoulders are complex and interconnected areas, and medical problems that affect one often affect the other, as well. Pain and dysfunction from injuries or conditions that impact the joints, muscles, and other structures can easily spread from the neck to the shoulder and from the shoulder to the neck.
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.
