Summary
This study demonstrates that a minimally invasive dorsal percutaneous approach using a cannulated mini compression screw is a feasible technique for stabilizing isolated hamate hook fractures, achieving anatomical reduction and stable fixation.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Traumatology
Background:
- Isolated hamate hook fractures often require surgical intervention due to high nonunion rates with conservative treatment.
- The traditional palmar approach for open reduction and internal fixation can be invasive.
Purpose of the Study:
- To refine surgical treatment for hamate hook fractures.
- To evaluate a minimally invasive dorsal percutaneous approach using a cannulated mini compression screw.
Main Methods:
- Artificial hamate hook fractures were created in cadaver hands.
- Fractures were stabilized percutaneously via a dorsal approach using a K-wire for guidance.
- A 3 mm cannulated mini compression screw was inserted, with fixation confirmed by imaging.
Main Results:
- Percutaneous fixation was successful in all cases, regardless of fracture location.
- Anatomical reduction of fracture fragments was achieved.
- Central screw placement ensured stable fixation without cortical disruption.
Conclusions:
- A dorsal percutaneous approach for hamate hook fractures is feasible and minimally invasive.
- Cannulated mini compression screws provide optimal positioning and stable fixation.
- This technique offers a safe alternative to traditional open approaches.
