摘要
目的:评价后路经椎弓根伤椎植骨成型结合四钉法固定治疗胸腰椎骨折的远期临床效果。方法:搜集2004年1月至2011年1月手术治疗的胸腰椎骨折病例56例,对比经椎弓根伤椎植骨成型结合四钉法固定组(A组)与传统四钉法固定组(B组)两组术前、术后及远期取出内固定后椎体形态各项指标及Frankel评分。结果:A组二期取出内固定物后较一期植入内固定物及取出前,椎体高度压缩丧失率和后凸Cobb角变化差异无统计学意义,较B组二期取出内固定物后伤椎变化差异有统计学意义。结论:后路四钉法固定配合伤椎植骨成型较之传统四钉法固定远期效果稳定,无内固定物松动及折断病例,骨折愈合后椎体骨质强度接近正常,远期对椎弓根钉无依赖。
Objective： Evaluation of long-term clinical effects for treatment of thoracolumbar fractures by fractured vertebral posterior pedicle bone graft molding combined four nails fixing.Methods： 56 cases of thoracolumbar fractures by surgical treatment were enrolled in our hospital since January 2004-January 2011.Comparing Indicators of vertebral body shape and Frankel score of two groups, which are group A with fractured vertebral posterior pedicle bone graft molding combined four nails for fixing and group B with the traditional four nails fixing, before surgery,after surgery and long-term removal of implants after surgery.Results： Followed-up cases of removing internal fixation in second phase and cases of implanting and before removing internal fixation in first phase of group A.The contrast between vertebral height compression rate of loss and kyphosis Cobb angle change was not statistically significant. The injured vertebral changes differences was statistically significant by contrast between group A cases of removing internal fixation in second phase and group B cases after removing the fixture in second phase.Conclusion： Long-term effects of thoracolumbar fractures by fractured vertebral posterior pedicle bone graft molding is stable in comparison with four-nails fixing.There is no case of internal fixation loose and broken. Bone strength is close to normal but not dependent on pedicle screw after fracture healing.
