Isolated dorsal dislocation of the lunate

Area of Science:

• Orthopedics
• Traumatology
• Anatomy

Background:

• Lunate dislocations are typically volar, often associated with perilunate injuries and significant trauma.
• Disruption of inter-carpal and radiocarpal ligaments necessitates substantial force.

Purpose of the Study:

• To report a rare case of dorsal lunate dislocation resulting from trivial trauma.
• To highlight a successful non-operative treatment approach for this unusual injury.

Main Methods:

• Closed manipulation and percutaneous K-wire fixation.
• Immobilization in a plaster cast.

Main Results:

• Successful closed reduction and fixation of the dorsal lunate dislocation.
• Rapid return to full function without neurological compromise or fracture.
• Demonstrated efficacy of non-operative management.

Conclusions:

• Dorsal lunate dislocations can occur with minimal trauma.
• Suspicion of dorsal lunate dislocation is warranted in cases of trivial trauma.
• Non-operative treatment can be effective, avoiding extensive surgery.
