摘要
目的 探讨对类风湿性寰枢椎不稳患者行后路经寰枢椎侧块关节螺钉固定融合治疗的手术方法并总结初步疗效。 方法 对 15例类风湿性寰枢椎不稳的患者采用后路经关节突侧块螺钉固定的方法 ,行寰枢椎 (C1,2 )即刻牢固固定。为保证确切的三点固定和植骨融合 ,同时辅以寰枢间植骨与钛丝固定。 结果 患者寰枢椎间稳定性得到恢复 ,无并发症发生 ;随访 6～ 14个月 (平均 10个月 ) ,15例患者均获骨融合。 结论 经后路寰枢椎侧块关节螺钉固定融合术可为类风湿性寰枢椎不稳的患者提供牢固的三维固定。
Objective To clarify the characteristics of the clinicopathological factors in cases of atlantoaxial instability due to rheumatoid and to introduce a new method for the treatment of this disease. [WT5”HZ]Methods [WT5”BZ]Fifteen patients with atlantoaxial instability due to rheumatoid were treated with posterior facet screws to obtain immediate rigid fixation of C 1 2 . In this series of patients, screw fixation was augmented with an interspinous C 1 2 strut graft which was wired in place to provide three-point stabilization and to facilitate bone fusion. [WT5”HZ]Results [WT5”BZ]In each patient fixation was satisfactory,and C 1 2 alignment and stability were restored without complication due to instrumentation. All patients showed osseous union (a mean follow up period of 10 months; range 6 14 months). [WT5”HZ]Conclusion [WT5”BZ]Posterior atlantoaxial facet screw fixation provides immediate three dimension rigid fixation of C 1 2 that is biomechanically superior to wiring or other fixation.
