Abstract

Background Data: Several articles reported on PVCR for correction of thoracolumbar deformities that followed tuberculous spondylodiscitis. But fewer focused on fixed lumbosacral deformity secondary to L5 pathology. Study Design: A retrospective cohort study. Purpose: This article aims to determine the degree of spinopelvic parameters correction after posterior vertebral column resection (PVCR) of the fifth lumbar vertebra (L5) in lumbosacral deformities secondary to pyogenic spondylodiscitis and define its relation to patients` clinical and functional outcomes. Patients and Methods: This retrospective study included 12 patients with kyphotic lumbopelvic spinal deformity secondary to healed pyogenic spondylodiscitis at the lumbosacral junction. The study included seven males (58.3%) and five females (41.7%) with a mean age of 37.5 ± 7.61 years. Patients were treated with posterior vertebral column resection (PVCR). Plain radiography, computed tomography (CT), and Magnetic Resonance Imaging (MRI) were performed on all patients, and the following parameters were measured using the Surgimap (version: 2.2.13) computer program: lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and focal deformity angle. Bony fusion is assessed using postoperative X-rays and/or CT. Visual Analogue Scale (VAS) for both leg and back pain and the Oswestry Disability Index (ODI) were assessed preoperatively and at the last follow-up. Results: The follow-up period lasted for 16 months (12–18). The solid union was achieved in all patients in 8.17 ± 1.52 months with no major postoperative complications. The mean kyphotic deformity was significantly corrected to -5.69° ± 6.77 (p
