Abstract:
Objective To investigate the clinical efficacy of asymmetric osteotomy via posterior adjacent vertebrae in the treatment of traumatic thoracolumbar kyphotic scoliotic deformity.Methods A retrospective case series study was conducted on the clinical data of 16 patients with traumatic thoracolumbar kyphotic scoliotic deformity admitted to our department from January 2012 to January 2017.There were 10 males and six females,aged (42.5 ±7.6) years (range,20-62 years).According to the location of injured vertebrae,there were two patients with T11,five with T12,six with L1,and three with L2,all of which had scoliosis deformity and obvious low back pain.All patients underwent asymmetric osteotomy via posterior adjacent vertebrae.The operation time and intraoperative bleeding were recorded.The imaging parameters such as kyphosis Cobb angle,scoliosis Cobb angle,distance between C7 plumbline and central sacral vertebral line (C7-CSVL),and distance between C7 plumbline and sagittal vertical axis (SVA) were measured before and after operation.At the same time,the visual analogue scale (VAS),Oswestry dysfunction index (ODI),and SRS-22 scale were used to evaluate the clinical efficacy.The AISA score was used to evaluate the neurological function recovery before and after operation.Results All patients were followed up for (26.3 ± 16.8) months (range,15-65 months).The operation time was (6.0 ± 1.4) hours (range,4.5-9.0 hours),and the intraoperative bleeding was (900.5 ± 360.8)ml (range,800-1600 ml).The kyphosis Cobb angle was improved from (70.3 ± 9.8) °before operation to (12.2 ± 2.9) ° after operation (P ＜ 0.01).The scoliosis Cobb angle was improved from (47.6 ± 11.6) ° before operation to (4.0 ± 0.9) ° after operation (P ＜ 0.01).The C7-CSVL decreased from preoperative (3.1 ±0.8)cm to postoperative (1.2 ±0.4)cm (P ＜0.01),and the SVA decreased from preoperative (5.0 ± 0.9) cm to postoperative (2.9 ± 0.5) cm (P ＜ 0.01).No severe complications such as spinal cord and nerve injury occurred.The VAS decreased from preoperative (6.8 ± 1.0) to (1.9 ± 0.9) points at the last follow up.The ODI decreased from (54.6 ± 4.2) ％ before operation to (8.1 ± 2.5) ％ at the last follow up.The SRS-22 score was increased from (64.6 ±7.5) points before operation to (87.4 ± 3.2) points at the last follow-up.In terms of the ASIA classification,two patients were improved from grade C to grade D after operation,and six patients were improved from grade D to grade E.Conclusion Asymmetric osteotomy via posterior adjacent vertebrae is safe and effective in the treatment of traumatic thoracolumbar scoliosis,with high correction rate of scoliosis and kyphosis at the same time.
