Isolated trapezoid dislocation is a rare injury. This case highlights an open dorsal dislocation of the trapezoid bone in a factory worker after a severe hand crush injury, involving multiple finger injuries and metacarpal fractures.

Area of Science:

  • Orthopedic Surgery
  • Trauma Care
  • Hand Surgery

Background:

  • Isolated trapezoid dislocation is an uncommon carpal bone injury.
  • High-energy trauma can lead to complex hand injuries, including carpal dislocations.
  • Open dislocations present unique challenges in management and outcomes.

Observation:

  • A factory worker sustained a high-energy crush injury to the left hand.
  • The injury resulted in an open dorsal dislocation of the trapezoid bone.
  • Associated injuries included multidigital mutilation and metacarpal fractures.

Findings:

  • The case demonstrates a rare instance of isolated trapezoid dislocation.
  • The open nature of the dislocation suggests significant trauma forces.

Related Experiment Videos

  • Concurrent metacarpal fractures and digital injuries complicate the presentation.

    • Implications:

    • This case underscores the importance of recognizing rare carpal injuries in high-energy hand trauma.
    • Management requires addressing both the dislocation and associated complex injuries.
    • Understanding such cases can improve treatment strategies for severe hand trauma.
