摘要
目的评价应用颈椎自锁PEEK椎间融合器前路减压治疗颈椎病的疗效。方法应用颈椎自锁PEEK椎间融合器治疗颈椎病患者18例,观察椎间融合器的稳定性和融合情况,采用Borden法测量椎间隙高度、颈椎曲度,对术前和术后JOA评分、椎间隙高度、颈椎曲度等指标进行统计学分析。结果 18例患者均获随访,时间6～42个月,未见严重并发症。术后6个月提示椎间骨性融合。椎间高度:术前为(3.26±0.68)mm,术后1周为(6.03±0.89)mm(P<0.01);术后6个月为(5.89±0.78)mm,与术后1周比较变化不大(P>0.05)。颈椎生理弧度:术前为(2.55±0.48)mm,术后1周为(3.24±0.67)mm(P>0.05);术后6个月为(8.14±1.17)mm,与术后1周比较明显改善(P<0.01)。末次随访根据JOA评分法进行疗效评价:优4例,良9例,可3例,差2例。结论颈椎自锁PEEK椎间融合器可以有效恢复颈椎生理曲度及椎间隙高度,可以获得满意的融合率,改善颈脊髓功能。
Objective To evaluate the clinical outcome of self-locking PEEK cage of cervical vertebra in treatment of cervical myelopathy. Methods 18 patients with cervical myelopathy were treated with self-locking PEEK cage of cervical vertebra. In all cases, the stability and the fusing of this instrument were observed. JOA scoring system was applied to evaluate the neurological function. Intervertebral height and cervical curve measured by Borden method be- fore and after operation. The data were compared statistically by one-way variation analysis. Results All of the pa- tients were followed up for 6 - 42 months, There were no severe adverse events. All patients obtained bone fusions in 6 months after surgery; Intervertebral height before operation, one week after operation, six months after operation were （3.26 ± 0. 68 ） mm, （ 6.03 ~ 0. 89 ） mm and （ 5.89 ± 0. 78 ） mm, respectively, showed there were significant differ- ences between the preoperation and one-week postoperative period （P 〈 0. 01 ） ; Cervical curve in the corresponding time above were （2. 55 ±0.48 ） mm, （ 3.24 ± 0. 67 ） mm and （ 8. 14 ± 1.17 ） mm, respectively, indicating that there was obvious improvement between one week and six months postoperatively（P 〈 0. 01 ）. According to the JOA score evaluation system, at the last follow-up period the excellent cases were 4, good 9, fair 3, and poor 2. Conclusions Self-locking PEEK cage of cervical vertebra can recover intervertebral height and cervical curve effetively, provide satisfactory postoperative fusion, and improve neurological function.
