Management of Acute and Chronic Thumb CMC Joint Dislocations.


Weeks D, Donato D
Hand Clin. 2022 May; 38(2):269-279.
PMID: 35465944.


Isolated dislocations of thumb CMC joints are rare injuries with serious functional implications. Patients suffering these injuries will have decreased pinch and grip strength. A high-energy, axially directed force on a flexed thumb typically causes dislocation. Chronically dislocated thumb CMC joints may be due to untreated remote trauma, hypermobility, or connective tissue disorders. Roberts and CMC stress view radiographs help identify joint dislocations. Treatment of these injuries includes closed reduction and immobilization, percutaneous pinning, open reduction with direct repair, and ligament reconstruction. Timely identification, timely treatment, and proper hand therapy often lead to adequate joint stability with minimal residual pain.
