Biodegradable gel shows promise for cartilage regeneration
A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new UBC research.
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.
What Causes Neck and Shoulder Pain?
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(s) and from the shoulder(s) to the neck.
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.
Scapula Fracture
A scapula fracture is an uncommon injury. The scapula, or shoulder blade, is a wide, flat bone that sits behind the rib cage. The scapula connects to the clavicle (collar bone) in the front of the body, and to the humerus (arm bone) at the side. Part of the scapula is lined with cartilage (the glenoid) and forms the socket of the ball-and-socket shoulder joint.
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.
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.
