Hamatometacarpal fracture-dislocation: A case report.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Traumatology

Background:

• Hamatometacarpal fracture-dislocation is an uncommon injury.
• Literature reports on this specific injury pattern are scarce.

Observation:

• A 26-year-old male presented with a coronal fracture of the hamate body.
• The fifth metacarpal base was interposed between the hamate fragments.
• The injury occurred in his dominant right hand.

Findings:

• Open reduction and internal fixation of the hamate were performed using a 2.0-mm cortical screw.
• The dislocated fifth metacarpal was stabilized with a Kirschner wire.
• At six months post-surgery, the patient had full range of motion and no pain.

Implications:

• This case demonstrates a successful surgical management strategy for hamatometacarpal fracture-dislocation.
• Early and appropriate surgical intervention can lead to excellent functional recovery.
• This approach may serve as a reference for managing similar rare hand injuries.
