Abstract

Background

To investigate the feasibility of percutaneous posterior quadcortical screw fixation of adjacent vertebrae for the treatment of lumbar degenerative diseases by imaging measurements.

Methods

A total of 192 patients with lumbar degenerative diseases who were treated in our hospital from October 2020 to October 2021 were included in this study. They have received percutaneous posterior quadcortical screw fixation of adjacent vertebrae. The insertion point was corrected by inserting quadcortical screws into cadaver specimens. The measured parameters in computed tomography three-dimensional (CT 3D) images main included safety range of screw track angle A, the minimum value of screw track Bmin, and the maximum value of screw track Bmax.

Results

The insertion point was 2 mm below the vertex of the herringbone ridge (the junction of the lateral edge of the lamina, the transverse process, and the base of the superior articular process). Screw track safety range angle A was 18.3°–19.7°. Average value range of minimum Bmin of screw trajectory was 4.99–5.39 cm. Maximum value of screw trajectory Bmax was 6.10–6.46 cm. Average length of screw track Bave was 5.55–5.93 cm.

Conclusion

Percutaneous posterior quadcortical screw fixation of adjacent vertebrae is feasible for the treatment of lumbar degenerative diseases.
