Episode notes
Volar Lunate Fragment Instability
- The volar lunate fragment can cause wrist instability when it involves disruption of volar ligaments.
- The carpus may follow this fragment, leading to volar instability and potential subluxation.
Plate Positioning and Screw Placement
- Position the volar plate as distal and ulnar as possible to capture the volar lunate fragment.
- Use K-wires for alignment and ensure screws do not penetrate the DRUJ to avoid complications.
Failed Initial Fixation Example
- A case where improper initial fixation of the volar lunate fragment led to fragment escape and carpal subluxation.
- The patient later developed wrist arthritis and required a spanning plate for stability.
