Carpal Instability - Wrist Ligament Injury
IntroductionCarpal instability occurs when the small bones in the wrist move out of position and compromise joint functioning. This may result when the ligaments that hold the bones together are torn or when the bones are fractured or affected by arthritis. Carpal instability causes ongoing pain and the loss of wrist functioning. Symptoms may improve with nonsurgical and surgical methods.
CausesCarpal instability occurs when the carpal bones move out of position. Chronic ligament weakening, as with arthritis, or ligament injury, such as from a fall, can cause malalignment of the carpal bones. Carpal bone fractures and deterioration contribute to carpal instability. When the carpal bones aligned inaccurately, the joints are unstable and may not function properly.
