Introduction:
Carpometacarpal joint dislocations are rare injuries that may be overlooked, particularly in high-energy trauma. Second and third carpometacarpal dislocations are especially uncommon due to the inherent stability of these joints.
Case Report:
A man in his 20s sustained second and third carpometacarpal joint dislocations following a high-energy road traffic injury, with an associated femoral head fracture-dislocation. Following urgent management of the hip injury, closed reduction of the carpometacarpal dislocations was performed. Stable anatomical reduction was confirmed clinically and radiographically. The hand was immobilized for 4 weeks followed by structured rehabilitation. At 2-year follow-up, the patient remained pain-free with full function and maintained joint congruity without instability or degenerative changes.
Conclusion:
Second and third carpometacarpal dislocations require careful clinical and radiographic assessment, particularly in polytrauma. When stable anatomical reduction is achieved, conservative treatment can provide excellent long-term functional outcomes.
