Palmar dislocation of the trapezoid--a case report

Area of Science:

• Orthopedic Surgery
• Hand and Wrist Surgery
• Trauma Surgery

Background:

• Carpometacarpal joint dislocations are uncommon injuries.
• Trapezoid dislocations, particularly open palmar types, are exceedingly rare.
• Complex wrist and hand trauma requires specialized management strategies.

Observation:

• A case of open palmar dislocation of the trapezoid bone is presented.
• This was associated with dorsal dislocations of the carpometacarpal joints of the index and long fingers.
• The injury involved significant disruption of the wrist and hand structures.

Findings:

• Open reduction was performed to address the dislocations.
• A primary limited wrist arthrodesis was utilized as part of the surgical management.
• The patient achieved good functional results following the intervention.

Implications:

• This case highlights a rare injury pattern in hand and wrist trauma.
• It underscores the effectiveness of open reduction and limited wrist arthrodesis in managing complex dislocations.
• The findings contribute to the understanding of surgical techniques for severe carpometacarpal and trapezoid injuries.
