目的评价椎弓根内固定技术治疗不同类型脊柱疾患的临床效果及安全性。方法回顾分析475例各种脊柱疾患经椎弓根内固定手术的临床资料,其中男216例,平均年龄(49.1±16.5)岁;女259例,平均年龄(48.7±13.9)岁。包括:腰椎滑脱217例,腰椎管狭窄76例,退变性腰椎不稳32例,胸腰椎骨折72例,脊柱侧凸60例,其他18例。采用椎弓根内固定技术包括:Dick55例,Steffee79例,CD54例,RF82例,DRFS59例,TSRH29例,USS19例,SOCON44例,Dynalock24例,Diapson22例,Tenor5例,CDH3例。融合范围:一个节段310例,二个节段96例,三个节段9例,与钩合用60例。结果428例(占90.1%)获(6.0±3.7)年随访。退变性腰椎滑脱、峡部裂性腰椎滑脱、腰椎管狭窄、退变性腰椎不稳及胸腰椎骨折患者术后的神经功能改善率分别为79.9%、87.9%、77.0%、89.3%和62.7%;脊柱活动改善率分别为90.5%、90.9%、83.6%、92.9%和52.5%;腰背痛改善率分别为89.9%、87.9%、85.2%、89.3%和84.8%;下肢疼痛改善率分别为93.9%、90.9%、93.4%、92.9%和79.7%。退变性腰椎滑脱、峡部裂性腰椎滑脱及胸腰椎骨折的椎体复位满意率分别为90.5%、87.9%和91.5%。SOCON技术对滑脱椎体复位满意率最高,为92.3%;其次是RF,为90.8%;Dick、Steffee及DRFS技术复位满意率为81.2%;其余内固定技术对滑脱?
Objective To evaluate the clinical results and safety of pedicle screw fixation for the treatment of spinal disorders. Methods From January 1988 to December 1999, 475 patients (216 males amd 259 females) with an average age of 49.1 years old in the male and an average age of 48.7 years old in the female, underwent pedicle screw fixation for spinal disorders. Diagnoses included 217 cases of spondylolisthesis, 76 lumbar stenosis, 32 degenerative lumbar spine instability, 72 thoracic or lumbar spine fractures, 60 scoliosis, and 18 others. The instrumentations were as follows: Dick 55 cases, Steffee 79 cases, CD 54 cases, RF 82 cases, DRFS 59 cases, TSRH 29 cases, USS 19 cases, SOCON 44 cases, Dynalock 24 cases, Diapson 22 cases, Tenor 5 cases, and CDH 3 cases. The fusion ranges involved one segment in 310 cases, two segments in 96 cases, and three segments in 9 cases. Hooks were applied in 60 cases. Results Four hundreds and twenty eight patients(90.l%) were followed up for (6.0±3.7)years. In the patients of degenerative spondylolisthesis, spondylolysis, lumbar stenosis, degenerative lumbar instability and thoracolumbar fracture, the amelioration of nerve function was 79.9%, 87.9%, 77.0%, 89.3%and 62.7%; the improvement of spinal motion was 90.5%, 90.9%, 83.6%, 92.9%and 52.5%; the amelioration of low back pain was 89.9%, 87.9%, 85.2%, 89.3%and 84.8%; and the amelioration of leg pain was 93.9%, 90.9%, 93.4%, 92.9%and 79.7%respectively. The mean reduction rate of degenerative spondylolisthesis, spondylolysis and spinal fracture was 90.5%, 87.9%and 91.5%respectively. The SOCON technique showed the highest reduction rate of an average of 92.3%, followed by RF of 90.8%, and Dick, Steffee and DRFS of 81.2%, while other instrumentations showed no satisfactory result in reduction. Complications occurred in 90 cases, in which 26 cases occurred during operation with the incidence of 6.1%, while 64 occurred after operation with the incidence of 15.0%. Conclusion Pedicle screws provide fixation of short segments with satisfactory clinical results and relatively high fusion rate. Perfect surgical technique is the key to reduce the incidence of complications.
