Summary
Surgical fixation of acetabular fractures using 3.5 mm cortical screws demonstrated satisfactory outcomes for large fragments. Additional buttress plating is recommended for comminuted fractures or non-compliant patients.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
Background:
- Acetabular fractures often result from high-energy trauma.
- Surgical management aims to restore joint congruity and function.
- Various surgical approaches and fixation methods exist for acetabular fractures.
Purpose of the Study:
- To evaluate the efficacy of 3.5 mm cortical screw fixation for acetabular fractures.
- To assess clinical and radiological outcomes following internal fixation.
- To identify factors influencing treatment success.
Main Methods:
- Retrospective review of 50 patients (51 fractures) treated between 1992 and 1995.
- Internal fixation using 3.5 mm cortical screws.
- Utilized various surgical approaches including modified extended iliofemoral, Kocher-Langenbeck, and ilioinguinal.
Main Results:
- Anatomical reduction (≤1 mm displacement) achieved in 40 fractures.
- Excellent or good clinical and radiological results in 38/44 patients at 2-year follow-up.
- Implant failure with loss of reduction occurred in 3 patients requiring revision.
Conclusions:
- 3.5 mm cortical screw fixation is satisfactory for acetabular fractures with large fragments.
- Consider additional buttress plating for highly comminuted fractures or patients with poor compliance.
