Closed treatment of a carpometacarpal fracture dislocation of the thumb, commonly referred to as a Bennett fracture, involves a non-surgical approach to realign the fractured bones. This type of fracture occurs at the base of the thumb and affects the articular surface of the metacarpal bone, which is crucial for thumb function. The procedure is characterized by the manipulation of the dislocated joint to restore proper alignment without the need for surgical intervention. To assess the extent of the injury, separate radiographs are obtained prior to treatment. The manipulation technique includes applying traction to the thumb while simultaneously extending, pronating, and abducting the metacarpal. Following the reduction of the fracture dislocation, a second set of radiographs is taken to ensure that the bones are properly aligned. Once alignment is confirmed, the thumb is immobilized using a thumb spica cast to facilitate healing and prevent further injury during the recovery process.
