🔍 Key Findings
- Mean SI joint reduction was 94.25%, exceeding the 90% target considered important to reduce screw loosening
- Mean sacral width purchase was 82.52%, with all screws achieving >60%—a threshold for reducing implant loosening risk
- All 20 screws were accurately placed within the sacral body, confirmed via CT or radiographs
- A 3D-printed drill guide and table-bound system facilitated consistent screw placement via minimally invasive technique
- Craniocaudal and dorsoventral angles were well controlled (mean CCA = –1.22°, DVA = 0.71°), demonstrating accurate trajectory
- No intraoperative complications were reported; all pilot holes drilled on first attempt
- Use of fluoroscopy and orthogonal imaging enhanced surgical accuracy and reduced malposition risk
- The system permitted screw placement through a sleeve that doubled as a muscle retractor, allowing implant delivery without disruption
