Chronic posttraumatic radial instability of the thumb metacarpophalangeal joint.

Radial collateral ligament injuries accounted for 35% of 26 patients undergoing surgery for lateral instability of the thumb metacarpophalangeal joint in a 3-year period. Nine patients with chronic radial instability presented with significant disability but with a symptom complex distinct from the weak pinch and grasp of chronic ulnar instability. Functional and clinical stability was obtained in these patients with a surgical procedure that consisted of repair of the callateral ligament at the site of injury, distal advancement of the abductor pollicis brevis tendon, and repair of the abductor aponeurosis.

Anterior drawer sign.

The traditional method for testing for anterior stability of the knee has often lead to inaccurate assessment of ligament stability because of the jerky nature of the test and the small amount of force applied. A method of testing the anterior drawer of a knee by flexing the hip and knee to 90 degrees and applying a steady upward force using the body weight as counterpull provides a more reliable test for assessing ligament stability. This method can be used to overcome hamstring spasm and causes less pain in the acutely injured knee.

The plaster slipper cast.

Since cast correction of congenital metatarsus adductus requires purchase of the cast on the foot only, a plastic slipper cast can accomplish this task. The correction of deformity and retainability equals or exceeds that of the short-leg cast. Ease of application and removal make this cast quite attractive in the small child. The use of this cast can be extrapolated to many conditions.
