Background: Rigid and severe spinal deformities can result from several etiologies and can only be effectively treated by a three-column spinal osteotomy in the form of vertebral column resection which is a demanding surgical procedure and is fraught with complications. However a single stage posterior vertebral column resection (PVCR) has gained acceptance as a less morbid procedure than front back two stage surgery. Aim: This study aims to present the technique and results of PVCR our cases of rigid and severe spinal deformities in terms of its capability to correct the deformity clinicoradiologically and its complications. Methods: This was a retrospective study of ten cases of rigid spinal deformity of various etiologies treated at our institute over a period of two years from March 2022 to December 2023. The study aims to present short-term results of posterior vertebral column resection (PVCR) in the treatment of severe and rigid spinal deformities viz a viz its ability to correct the deformity and its complications. Results: The mean age of the patients was 26.4 years. Congenital deformity was seen in six, post traumatic deformity in two and post tumor and post laminectomy deformity in one patient each. Deformity involved dorsal spine in six, dorso-lumbar region in three and lumbar region in one patient. The average operative time was 7.4 hours with an average blood loss of 1800 ml. The average number of transfusions required was 3.9 and average number of days spent in Intensive Care Unit was 4.5 days. The average preoperative and post-operative kyphosis was 60.3 and 22.2 degrees respectively, scoliosis was 48 and 18 degrees respectively, and sagittal imbalance was 35.5 and 11.6 degrees respectively. The mean preoperative and post-operative coronal imbalance was 30 mm and 11 mm respectively. There was one case of mortality in our series. Conclusion: We have been able to demonstrate the ability of PVCR to correct severe and rigid deformities of the spine in both the coronal and sagittal planes of various etiologies and in different age groups.
