MR imaging of traumatic and overuse injuries of the wrist and hand in athletes.

Traumatic and overuse injuries of the hand and wrist are common in athletes. Increasingly, MR imaging is being used to complement clinical and radiographic assessment in the diagnosis and management of these injuries. MR imaging is able to image accurately the bones, tendons, ligaments, nerves, and other small structures of the hand and wrist.

Overuse and impingement syndromes of the shoulder in the athlete.

Overuse and impingement syndromes in the shoulders of athletes are predominantly caused by instability of the glenohumeral joint. Glenohumeral joint instability is usually acquired from repetitive overuse of the rotator cuff and shoulder girdle muscles, or injury of the static and dynamic stabilizers of the glenohumeral joint. Congenital hypermobility of the joint may also contribute to these syndromes in some individuals.
