Summary

Carpometacarpal dislocation of the four long fingers is rare but treatable. Open reduction and intramedullary pinning led to excellent grip strength and function in two patients.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • Carpometacarpal (CMC) joint dislocations, particularly of the four long fingers, represent uncommon yet potentially diagnostically challenging injuries.
  • Prompt recognition and appropriate management are crucial for optimal functional outcomes in hand trauma.

Observation:

  • Two cases of CMC dislocation involving the four long fingers were diagnosed and managed in an emergency setting.
  • Treatment involved open reduction and stabilization using intramedullary pinning.

Findings:

  • Follow-up averaged 30 months, revealing good outcomes in both cases.
  • Patients demonstrated excellent grip strength, with no residual deformity, instability, or limitations in prehension.

Implications:

  • The study highlights the effectiveness of open reduction and intramedullary pinning for CMC dislocations of the long fingers.
  • Early diagnosis and surgical intervention are recommended to prevent long-term functional deficits.
  • This approach offers a reliable method for restoring hand function after these rare injuries.
