Summary
This study presents a safe and effective CT-guided technique for removing misplaced acetabular screws after complex fracture surgery. The minimally invasive approach offers a rapid solution with no observed complications.
Area of Science:
- Orthopedic Surgery
- Medical Imaging
- Minimally Invasive Procedures
Background:
- Complex acetabular fractures typically require open reduction and internal fixation using screws and plates.
- Post-operative imaging may reveal misplaced screws, necessitating intervention.
- Accurate screw placement is crucial for successful acetabular fracture repair.
Observation:
- Two cases of misplaced acetabular screws were identified post-operatively.
- A CT-guided technique was employed for screw removal in the decubitus position.
- Procedure involved preliminary imaging, k-wire advancement, and screwdriver insertion under CT monitoring.
Findings:
- The average total procedure time for CT-guided screw removal was 30 minutes.
- No significant intra-procedural or post-procedural complications were observed.
- The technique demonstrated simplicity and safety in the cases studied.
Implications:
- CT-guided removal offers a viable solution for misplaced acetabular screws.
- This minimally invasive technique may reduce the need for revision surgery.
- Further studies could explore the broader application of this method in orthopedic interventions.
