Simultaneous multiple carpometacarpal joint dislocations with trapezium fracture and trapezoid dislocation: A case report

Simultaneous dislocations of multiple carpometacarpal (CMC) joints combined with trapezium fractures and trapezoid dislocations at the scaphotrapeziotrapezoidal (STT) joint are extremely rare and often overlooked during initial evaluation, especially in polytrauma settings. Early diagnosis is challenging due to subtle radiographic findings and the potential presence of more life-threatening injuries. While X-rays are useful for the initial evaluation, advanced imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI) are crucial for accurately identifying fracture patterns and associated dislocations. Treatment options range from closed reduction and immobilization to surgical fixation, depending on the complexity and stability of the injuries. Prompt recognition and appropriate intervention are essential for optimal functional recovery.
