Isolated Carpo-Metacarpal Dislocation of the Thumb

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Traumatology

Background:

• Isolated trapezio metacarpal joint dislocations are exceedingly rare in medical literature.
• Previous reports often involve associated injuries such as fractures of the trapezium or metacarpal base.

Observation:

• A case of an isolated carpometacarpal joint dislocation of the right thumb in an adult is presented.
• The dislocation was successfully treated using conservative methods, specifically closed reduction and immobilization.

Findings:

• At a 15-month follow-up, the patient demonstrated complete hand function.
• No clinical or radiological signs of instability or post-traumatic arthritis were observed.

Implications:

• Conservative management, including closed reduction and immobilization, can be effective for isolated trapezio metacarpal joint dislocations.
• Surgical intervention may be necessary for managing unstable dislocations.
