BIOMECHANICAL CHANGES IN CERVICAL SPINE SEQUENCING AFTER RIGID LUMBAR STABILIZATION

Abstract

Objective: Surgical stabilization of the thoraco-lumbar spine can induce biomechanical changes in other spinal regions, potentially influencing postoperative outcome. This study detected biomechanical changes in cervical spine sequencing and identify preoperative parameters associated with these changes following rigid stabilization surgery for degenerative lumbar spinal disease. Materials and Methods: Twenty patients (10 males and 10 females, mean age 64.6 years) with lumbar degeneration receiving rigid stabilization (polyaxial screws and titanium rods) were included in the study. Preoperative and postoperative anterioposterior and sagittal scoliosis x-rays were retrospectively evaluated by an independent researcher using SurgimapR (Nemaris Inc., USA). Preoperative and postoperative cervical spine parameters were compared using Wilcoxon test. A p
