Carpal Fractures and Ligamentous Instabilities

Carpal Fractures

Carpal Fractures

The human wrist joint is a complex arrangement of small bones and ligaments that form a mobile yet stable link from the powerful forearm to the hand. The normally functioning carpus can position the hand precisely relative to the forearm and provides remarkably stable transmission of forces. Motion and stability of […]

Partial Thickness Rotator Cuff Tears: Treatment

It is important to understand that not all full thickness rotator cuff tears are alike, and that some complete tears are compatible with excellent function and minimal discomfort. Armed with biomechanical models, basic engineering principles, and kinematic studies of patients with known rotator cuff tears, Burkhart defined the “functional rotator cuff tear.”

His reasoning was […]

Stiffness

Stiffness after surgery for open anterior instability is infrequently noted in literature and the incidence of this complication is probably under-reported. Certain repairs were designed to limit external rotation and hence the risk of recurrence, so loss of motion was not considered a complication.

In some settings (e.g., capsular reconstruction or revision surgery), limited external […]

Glenohumeral Joint

The GH joint is a diarthrodial joint with minimal bony constraint, allowing it the largest range of motion of any major diarthrodial joint in the body. The GH joint has been described as being similar to a golf ball on a tee, with a large humeral head balanced on a smaller glenoid.

The GH joint […]

Periarticular Ligamentous Tissue: A Biochemical and Physiologic Assessment-Key Points

Key Points

Although tendons and ligaments are composed primarily of fibrillar collagens, they have entirely different functions. Tendons are a conduit, connecting muscle to bone. Ligaments are short bands of fibrous tissue that bind bone to bone. Collagen is the single most abundant animal protein in mammals. Collagen molecules assemble into characteristic fibers responsible for […]

Ligaments and Injuries

Anterior cruciate ligament injuries ACL injuries of the knee are the most common injuries to the knee; the loss of an ACL not only produces abnormal kinematics but also frequently results in major degenerative changes in the knee.

Anatomy The human ACL is a complex structure at every level. The ligament is designed to act […]
