Background

Posterior spinal fusion is a common procedure, but manual pedicle screw planning is time-consuming, cognitively demanding, and may not fully leverage patient-specific anatomy.

Purpose

This study aimed to develop and evaluate an automated pedicle screw planning framework for multi-level fusion, designed to simultaneously optimize clinical safety, biomechanical stability, and screw head alignment.

Methods

The proposed automated screw planning workflow was compared with clinical standard manual planning on 20 clinical computed tomography (computed tomography) scans comprising 238 pedicle screws.

n = 238 pedicle screws

Results

nearly all screws were placed safely with no measurable breach

87.8%

Grade A

12.2%

Grade B

More results

The automated method also achieved a median relative improvement of 74.9% (P<0.001) in hounsfield unit coverage and a median relative improvement of 58.6% (P<0.001) in screw-head misalignment.

“

Conclusion

The assessed approach carries significant clinical potential in simplifying the intraoperative workflow while improving the surgical outcome.
