Effect of vertebral rotation on adjacent segment degeneration after the early stage of lumbar fusion surgery.

ABSTRACT:

Objective

Related studies have shown that the torsional vertebral after fused significantly increase adjacent disc stress and accelerate degeneration. This suggests that vertebral rotation (VR) may accelerate adjacent segment degeneration (ASD). To investigate: (1) the correlation between VR and radiographic adjacent segment degeneration (rASD) after the early stage of lumbar fusion (2), the incidence of rASD with different VR degrees (3), whether the incidence of rASD can be reduced by surgically reducing instrumented vertebrae (IV) rotation.

Methods

A retrospective analysis was conducted on the cases of 195 patients with lumbar degenerative disease (LDD) who were selected based on inclusion and exclusion criteria. The grade and angle of VR were measured for accurate analys
