颈椎前路减压高分子材料Solis颈椎间融合器植入术

Application of solis cage via the cervical vertebra anterior approach

目的观察颈椎前路减压Solis椎体间融合的临床效果.方法对35例颈椎疾病患者采用前路减压Solis植入,随访3～36个月,采用JOA评分法观察术后神经功能恢复,X线检查观察融合节段的融合时间,融合节段屈伸位Cobb角改变,椎间高度的改变情况.结果神经功能JOA评分法术后12个月优良率91.3%.影像学检查,所有病例手术节段均在3个月内融合,融合率100%,融合节段屈伸位Cobb角改变小于5°,手术节段椎间高度增加1～2 mm,术后最长36个月无椎间高度丢失.结论 Solis用于颈椎疾病的治疗融合率高,融合后稳定性好,神经功能改善优良率高,术后撑开椎间高度丢失低.

Objective To observe the stability and fusion effect of cervical vertebra fusion with solis cage trans anterior approach. Methods Thirty-five cases of cervical diseases were treated with decompressed trans anterior approach and implanted with solis cage. Recovery of nerve function was observed by JOA score after follow-up from 3 to 36 months, and the fusion state, stability and changes of intervertebra height of fusion segment were evaluated by X ray. Results Excellent-good rate of improvement of nerve function was 91.3 % 12 months after JOA score. Fusion segment of all the cases was fused during 3 months. The changes of Cobb angle was less than 5 degree. Loss of height of intervertebra was not happened. On the contrary, gain of 1-2 mm was observed. Conclusion Treatment of cervical disease with solis cage has some advantages such as higher fusion rate, better stability, higher recovery rate of nerve function and low rate of loss of intervertebral height.
