Telamon融合技术在下腰椎不稳治疗中的作用

目的回顾性分析了Telamon融合技术在治疗下腰椎不稳定方面的作用。方法本组共68例，均为单节段病变，平均年龄49岁，腰椎椎弓崩裂伴滑脱者27例，腰椎退变性不稳者41例，术前病程平均28．6月，Oswestry残疾指数平均48．5%。所有病例均行后路减压、椎弓根螺钉内固定及Telamon椎体间融合术，其中全椎板切除者5例，双侧椎板间扩大开窗者63例。结果术后随访平均11．8个月，最后随访时Oswestry残疾指数平均7．5％，复查X线片均获良好的骨性融合，无明显不稳定征象。结论Telamon融合技术能提供良好的骨性融合并维持良好的椎体间高度和腰椎的生理性前凸，由于其本身并不具有即刻稳定性，故应在坚强内固定的保护下应用，获得良好效果的关键在于正确的手术适应证。

The role of the Telamon fusion technique in the treatment of the instability of low lumbar spine

Objective Retrospective study on the role of the Telamon fusion technique in the treatment of the instability of low lumbar spine. Methods Sixty-eight cases of low lumbar spine instability including 27 cases with spondylolisthesis and 41 cases with degenerative instability, with an average age of 49 years, underwent posterior decompression, pedicle screw fixation and Telamon fusion. Of these cases, 5 cases underwent laminectomy and 63 cases underwent bilateral fenestration procedure. The Oswestry disability index was averaged 48.5% before the operation. Results The follow-up period was averaged 11.8 months. At the final examination, good intervertebral fusion was seen in all cases and no instability was found. The Oswestry disability index was averaged 7.5%.Conclusion The Telamon fusion technique can provide good intervertebral fusion and maintain good intervertebral space and good lordosis of the lumbar spine. Without the protection of the stable fixation, the Telamon can not be used alone because it can not provide the immediate stability. The good result of the surgery depends on the correct surgical indication.
