经后路椎弓根钉棒内固定联合3D打印治疗强直性脊柱炎合并胸腰椎骨折患者的短及中期随访研究
Short-term and mid-term follow-up study of posterior pedicle screw fixation combined with 3D printing for patients with ankylosing spondylitis complicated with thoracolumbar fracture
摘要
Abstract
Objective To investigate the short-and medium-term effects of posterior pedicle screw fixation combined with 3D printing in the treatment of patients with ankylosing spondylitis(AS)and thoracolumbar fractures.Methods Ninety patients with AS and thoracolumbar fractures treeated in our hospital from February,2014 to February,2018 were selected,and were divided into a routine group and a 3D group,with 45 cases in each group.The routine group was treated with posterior pedicle screw fixation,and the 3D group with posterior pedicle screw fixation and 3D printing.The operation time,surgical bleeding volume,postoperative drainage volume,accuracy of nail placement,and Japanese Orthopaedic Association evaluated the treatment score(JOA),convex Cobb angles,anterior and posterior edge heights of the injured vertebrae,kyphosis Cobb angles,and heights of the anterior and postriormargin of the injured vertebrae 1 week,2 weeks,6 months,and 12 months after the operation were compared between these two groups.Results The operation time,surgical bleeding volume,and postoperative drainage volume were(113.14±13.85)min,(195.11±23.62)ml,and(184.73±21.42)ml in the 3D group,which were lower than those in the routine group(all P ＜ 0.05).The accuracy of nail placement was 95.56％(344/360)in the 3D group,and was 82.22％(296/360)in the routine(P＜ 0.05).The JOA scores 1 week,2 weeks,and 6 months after the operationwere(20.42±2.38),(20.7±2.43),and(22.47±2.69)in the 3D group,which were higher than those in the routine group(an P ＜ 0.05).6 and 12 months after the operation,the kyphosis Cobb angles were(8.69±2.25)° and(9.08±2.50)°,which were lower in the 3D group than in the routine group; and the heights of the anterior and posterior margin of the injured vertebra were(90.47±7.36)％and(90.73±7.45)％,which were higher than those in the routine group(P ＜ 0.05).Conclusions Posterior pedicle screw fixation combined with 3D printing for patients with AS and thoracolumbar factures has short operation time,less bleeding,low postoperative drainage,accurate nail placement,and reduced postoperative kyphosis Cobb angle.The height ratio of the anterior and posterior margin of the injured vertebrae promotes the recovery of thoracolumbar function.关键词
