An injury to the thumb caused by falling directly onto it when it is outstretched, resulting in tearing or stretching of the ligaments of the main thumb joint.
A sprain of the ligament that is attached to the joint of the thumb and controls the bending and straightening motions as well as side-to-side movements of the thumb. Skien’s thumb results in instability of the thumb and a loss of function. There may be pain and swelling in the area. The ability to bring together the ends of the thumb and forefinger may be limited. X rays may indicate a complete rupture of the ligament. If the thumb joint is sufficiently stable, a thumb cast or brace may be worn for 3 to 6 weeks to immobilize the joint and allow healing. If the ligament is completely ruptured, surgery is usually necessary to reconnect the torn ends of the ligament.
An injury to the ulnar collateral ligament of the metacarpophalangeal joint of the thumb.
