posttraumatic kyphosis is a major problem that affects the lifestyle and activity of the patients. We are studying the outcomes of surgical treatment by VCR and whether it benefits the patients clinically or not. This article Orthopedic Surgery Department, Faculty of Medicine –Zagazig University Email: mdesawy@zu.edu.eg aimed to determine the degree of spinopelvic parameters correction after PVCR of neglected malunited vertebrae and clinical improvement of the patients postoperatively. Methods: A retrospective cohort study of a total of 25 patients with posttraumatic kyphosis that was included in this study. The average age was 26.0 ± 8.15 (range 19-40) with 60% females and 40% males. Patients were treated with PVCR. Plain radiography, computed tomography, and MRI were performed on all patients, and the following parameters were measured using the Surgimap (version: 2.2.13) computer program: Thoracic kyphosis (TK), Lumbar lordosis (LL), Pelvic incidence (PI), Sacral slope (SS), Pelvic tilt (PT) and Sagittal vertical axis (SVA). Bony fusion is assessed using postoperative radiograph and/or computed tomography. Visual analog score for pain and the Oswestry Disability Index were assessed preoperatively and at the last follow up. Results: The average follow-up period was 20.21 ± 7.47 (range 18–24 months). VAS score decreased from (5.80 ± 1.78) preoperatively to (3.0 ± 0.70) postoperatively while the ODI score showed significant decrease from (35.0±11.63) preoperatively to (18.40±2.60) postoperatively. The local kyphotic angle decreased from 54.60±8.76 to 11± 6.97. The mismatch between pelvic incidence and lumbar lordosis declined from 16.40 ± 7.69 to 7.60 ± 2.85. The lumbar lordosis showed significant change from 68.40 ± 13.04 to 51.40 ± 8.76. There were no significant changes in the sacral slope nor the pelvic tilt postoperatively Conclusion: PVCR provides significant correction of pelvic parameters and clinical functions of patients with fixed posttraumatic deformity Keywords: Vertebral column resection, Spinopelvic, Kyphosis
