Midcarpal instability (MCI) is the result of complex abnormal carpal motion at the midcarpal joint of the wrist. It is a form of non-dissociative carpal instability (CIND) and can be caused by various combinations of extrinsic ligament injuries that then result in one of several subtypes of MCI.
How do you treat midcarpal instability?
Most patients with midcarpal instability respond to conservative measures that include anti-inflammatories, avoidance of aggravating activities, special splints, and physical therapy.
How common is midcarpal instability?
Symptomatic midcarpal joint instability is an uncommon clinical entity. It was included in the concept of nondissociative type of carpal instability as advocated by Dobyns et al in 1985, 1 where there is no disruption of the intrinsic ligaments connecting the carpal bones.
