摘要
目的探讨后路椎弓根钉系统治疗退变性腰椎侧凸的短期临床疗效。方法 2007年12月～2011年6月收治的退变性腰椎侧凸患者18例,其中男11例,女7例;均采用后路椎管减压、椎间植骨融合(10例)或后外侧植骨融合(8例)椎弓根钉系统内固定,分析患者术前、术后VAS腰腿痛评分、Cobb’s角;术后并发症发生情况。结果腰腿痛VAS评分术后较术前明显减低(P<0.05);冠状位Cobb’s角术前平均31.56°,术后改善至平均14.8°(P<0.01);矢状位术前平均12.6°,术后改善至平均36.0°(P<0.01)。18例患者均获得随访,随访时间平均3.2年(1年4个月～4年8个月),至末期随访,无椎弓根钉棒松动及断裂现象/椎间Cage融合器无明显下沉、植骨均达骨性融合。结论椎管充分减压、椎间或椎旁植骨融合、后路椎弓根钉系统内固定治疗退变性腰椎侧凸畸形可获得满意的短期临床疗效,中远期疗效有待于进一步随访。
Objective To discuss clinical observation of treatment in degenerative lumbar scoliosis with posterior pedi- cle screw instrumentation. Methods Between Dec 2007 to Jun 2011,18 patients （11 males and 7 females） cases de- generative lumbar scoliosis who underwent posterior decompression,pedicle screw orthomorphia and fusion. Low back pain（LBP） and leg pain at preoperative and postoperation were evaluated according to Visual Analogue Scale （VAS）, Cobb angle of the patients were assessed before and after the operation. Observe the complications. Results VAS scales of LBP,leg pain of postoperation were significantly lower than preoperative （P 〈 0.05）,An average coronal cor- rection of the lumbar curves was from 31.56~ to 14.8^（P 〈 0.01 ）;In the sagittal plane,lumbar lordosis was averaged from 12.6~ to 36~ （P 〈 0.01 ）. All patients were followed up for l^4years and 4months（averaged 2.8 years）. There were excellent maintenance of correction and good fusion;no implant loose,shift and fragmentation;no pseudoarthroses was noted at final follow-up. Conclusion Posterior decompression,pedicle screw orthomorphia and fusion in the treatment of degenerative scoliosis have excellent clinical results, satisfactory results is on the basis of sufficient preoperative preparation and correct operation.
