Abstract

Abstract:

BACKGROUND: Vertebral column resection is the frequently mentioned spinal orthopaedic concept. Due to the high requirement of the operation skill, difficulty and more complications, the previous studies have reported from different aspects, and many researchers have focused on the analysis of complications, that may be related with the procedure and manner.
OBJECTIVE: To analyze the efficacy and complications of posterior vertebral column resection combined with titanium screw rod fixation for the treatment of severe spinal deformity.
METHODS: We retrospectively analyzed 48 patients with severe spinal deformity who treated with posterior vertebral column resection and titanium screw rod fixation, with an average removal of 1.6 vertebral. The patients were followed-up for 15-64 months. The Cobb angle (coronal plane and sagittal plane) of the patients before treatment, after treatment and in the final follow-up was analyzed, and the relative complications of the surgery were analyzed.
RESULTS AND CONCLUSION: The patients with spinal deformity were divided into five categories, included kyphoscoliosis (n=11), severe scoliosis (n=20), congenital spinal deformity (n=4), spherical kyphosis (n=3), and angular kyphosis (n=10). The average coronal plane deformity angle of the patients was corrected from 84° preoperation to 35° postoperation, with the total correction rate of 54%. The average sagittal plane deformity angle was corrected from 90° preoperation to 42° postoperation, and the sagittal plane Cobb angle was decreased for 48°. The mean operation time was 545 minutes (204–1 355 minutes), the intraoperative blood loss was 1 610 mL (50–8 244 mL), and the average blood loss was 65%. After treatment, 31 cases had complications, including 13 cases of intraoperative neurological dysfunction (observed through electrophysiological monitoring and wake), permanent neurological dysfunction did not occur after timely treatment. The posterior vertebral column resection and titanium screw rod fixation can obtain better effect in the treatment of severe spinal deformity, but the procedure has high complications and is difficult for operation.

Key words: kyphosis, scoliosis, spinal curvatures, internal fixators
