Synopsis

Carpometacarpal (CMC) joint fractures and dislocations are rare hand injuries often resulting from a fall onto a flexed wrist. Treatment options vary as there is no consensus due to these injuries' rarity. The CMC joints connect the hand and carpal bones, with each joint playing a distinct role, making the injuries examined in three groups.

These joints have a robust design due to strong ligaments and unique articulations. Extensor tendons contribute to hand stability, and injuries to these structures can have varying clinical consequences. Despite the absence of a universally recognized categorization method, fractures and dislocations are generally categorized based on displacement direction, joint count, and injury nature.

Diagnosing carpometacarpal (CMC) joint fractures and dislocations involves detailed examination and imaging, including X-rays, CT scans, and MRIs. These injuries are treated to restore the hand's anatomy and functionality. Treatment varies widely and may include conservative measures, open reduction, or internal fixation, with no consensus due to the rarity of such injuries.

 Complications include metacarpophalangeal joint stiffness, which can lead to contractures. Despite the severity of these injuries, both surgical and non-surgical treatments often result in positive outcomes, with delayed treatment, inaccurate articular restoration, and secondary fracture displacement leading to poorer outcomes.

Key to successful treatment is early detection and a comprehensive approach including potential surgical intervention and rehabilitation.
