Abstract

Background data: posttraumatic kyphosisaffects the lifestyle and activity of the patients. This article aimed to determine the degree of spinopelvic parameters correction and clinical improvement of the patients after PVCR of malunited vertebrae.

Methods: A retrospective cohort study of a total of 25 patients with posttraumatic kyphosis that were 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, CT, and MRI were performed on all patients, and the following parameters were measured: 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. VAS score for pain and ODI 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) to (3.0 ± 0.70) postoperatively while the ODI showed significant decrease from (35.0±11.63) 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
