Official Description

Closed treatment of carpometacarpal dislocation, thumb, with manipulation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Closed treatment of a carpometacarpal (CMC) dislocation of the thumb involves a non-surgical procedure aimed at realigning the bones at the base of the thumb where it meets the wrist. This type of dislocation is characterized by the displacement of the thumb's metacarpal bone from its normal position in the CMC joint. Such dislocations are uncommon, primarily due to the robust nature of the volar ligament, which provides significant stability to the joint. The procedure is performed without making any incisions, hence the term 'closed treatment.' It requires skilled manipulation to restore the thumb's normal anatomy. Prior to the manipulation, imaging studies, specifically radiographs, are obtained to assess the extent of the dislocation and to rule out any associated fractures. The manipulation technique typically involves applying traction to the thumb while simultaneously extending, pronating, and abducting the metacarpal to facilitate the reduction of the dislocation. Following the reduction, additional radiographs may be taken to ensure that the bones are properly aligned and that the joint is stable.

1. Indications

Closed treatment of carpometacarpal dislocation of the thumb is indicated for the following conditions:

  • Carpometacarpal dislocation of the thumb This procedure is specifically performed when there is a dislocation at the CMC joint of the thumb, which may present with pain, swelling, and deformity of the thumb.
  • Absence of concomitant fracture The procedure is indicated when the dislocation occurs without any associated fractures, as the presence of fractures may require different treatment approaches.

2. Procedure

The closed treatment of a carpometacarpal dislocation of the thumb involves several key procedural steps:

  • Step 1: Initial Assessment The healthcare provider begins by assessing the patient's thumb for signs of dislocation, including deformity, swelling, and pain. Radiographs are obtained to confirm the diagnosis and evaluate the extent of the dislocation.
  • Step 2: Preparation for Manipulation Once the dislocation is confirmed, the patient is positioned comfortably, and the thumb is prepared for manipulation. The provider may apply local anesthesia to minimize discomfort during the procedure.
  • Step 3: Manual Reduction The dislocation is manually reduced by applying traction to the thumb while simultaneously extending the metacarpal. The provider may also use pronation and abduction techniques to facilitate the reduction of the dislocated joint back into its proper position.
  • Step 4: Confirmation of Alignment After the manipulation, a second set of radiographs is obtained to confirm that the thumb is properly aligned and that the dislocation has been successfully reduced. This step is crucial to ensure that the joint is stable and to prevent future complications.

3. Post-Procedure

Following the closed treatment of a carpometacarpal dislocation of the thumb, the patient may be advised to rest the thumb and avoid any activities that could stress the joint. The provider may recommend the use of a splint or brace to immobilize the thumb during the initial healing phase. Follow-up appointments are typically scheduled to monitor the recovery process and to assess the stability of the joint. Patients are also instructed to report any signs of complications, such as increased pain, swelling, or loss of function, which may require further evaluation.
