Laser-etched allograft may have positive short-term results in articular cartilage defects
Results published in Journal of Orthopedic Surgery showed that a thin, laser-etched osteochondral allograft yielded positive short-term clinical outcomes in isolated articular cartilage defects in the knee.
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.
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.
Hill-Sachs Lesion Injury and Deformity
A Hill-Sachs injury to the shoulder can occur due to a shoulder dislocation, resulting in a Hill-Sachs lesion or a Hill-Sachs deformity of the head of the humerus bone (the upper arm bone).As the bones in the shoulder joint dislocate, the round humeral head (the ball on the top of the arm bone) can strike the edge of the glenoid bone (the socket) with force. This creates a compression fracture in the humeral head. A small divot in the bone is often seen on MRI, and larger Hill-Sachs injuries may also be seen on an X-ray.
