Carpometacarpal Joint Dislocation Rare Injury: A Case Series

Background: Carpometacarpal (CMC) joint fracture dislocations are extremely rare, representing less than 1% of all hand and wrist fractures. These injuries are frequently missed or misdiagnosed, occurring primarily in young adults due to axial loading injuries or in the elderly following falls. Early diagnosis and appropriate management are crucial for optimal recovery. Cases: This series presents 12 cases of CMC joint dislocations in patients aged 19 to 50, including both males and females. The injuries resulted from various mechanisms such as falls, sports injuries, and accidents. The majority of cases involved dorsal dislocations of the 2nd, 3rd, and 4th CMC joints. Treatment included closed reduction, K-wire fixation, and cast immobilization. Result: All patients achieved good functional recovery with minimal stiffness and satisfactory alignment within six to ten weeks. Regular follow-up and structured physiotherapy played significant roles in ensuring optimal outcomes. The consistent application of early intervention techniques proved effective in managing these complex injuries. Conclusion: Despite their rarity, CMC joint dislocations require a high index of suspicion for diagnosis and prompt, precise treatment. This case series highlights the importance of early intervention, demonstrating that with appropriate management, excellent functional outcomes can be achieved in patients with CMC joint dislocations.
