This prospective randomized controlled trial evaluated the 'Pre-set Screw Path Technique (PSPT)' in 113 patients undergoing cervical posterior laminoplasty. The PSPT group demonstrated no intraoperative spinal cord or nerve root injuries, while the control group had one incident. The PSPT also significantly reduced operative time (86.07 vs. 106.29 min) and blood loss (111.09 vs. 168.19 ml).
Key findings
- No spinal cord or nerve root injuries occurred in the PSPT group (0/55) compared to 1.72% in the control group.
- Operative time was significantly shorter in the PSPT group (86.07 vs. 106.29 min, P < 0.05).
- Intraoperative blood loss was significantly lower in the PSPT group (111.09 vs. 168.19 ml, P < 0.001).
- The incidence of axial symptoms was lower in the PSPT group (9.1% vs. 25.9%, P = 0.020).
Why it matters
The findings suggest that the Pre-set Screw Path Technique may enhance surgical safety and efficiency in cervical laminoplasty, potentially leading to better patient outcomes and reduced complications.
