颈前路减压植骨融合内固定术在治疗颈性眩晕中的作用

目的 探讨分析颈前路减压植骨融合内固定术在治疗颈性眩晕中的作用及其作用机制.方法 回顾分析了1998～2005年本治疗组采用颈前路减压植骨融合内固定术所治疗的伴有颈性眩晕的颈椎病患者32例.观察比较术前、术后颈椎正侧位及动力位X片和症状改善情况,并进一步通过颈性眩晕症状和功能评分法对患者术前及术后进行评定.结果 所有患者术前X片上都有不同程度的颈椎不稳或椎间盘突出现象,单节段不稳者9例,两节段者13例,三节段者7例.单节段椎间盘突出者10例,两节段者15例,三节段者7例.所有患者行颈前路减压植骨融合内固定术后获10～48个月的随访,平均26个月,术后有效率为87.5%,症状和功能评分分值有明显提高(均数由术前13.89提升到术后23.98),具有统计学意义(＜0.05),结论 颈前路减压植骨内固定术在治疗伴有颈性眩晕颈椎病中对颈性眩晕症状具有良好改善作用.

Anterior route cervical discectomy and internal fixation in the treatment of cervical vertigo

Objective To investigate the curative effect and mechanism of anterior route cervical discectomy and internal fixation in the treatment of cervical vertigo. Methods Thirty two patients who underwent anterior cervical discectomy and internal fixation for cervical vertigo were reviewed retrospectively. Observe and compare the lateral views in flexion and extension of the pre and postoperative cervical roentgenograms. The curative effect was evaluated according to the satisfactory extent of patients and evaluation Scale for cervical vertigo. Results Cervical instability or intervertebral disk hernia was found in all patients. Cervical instability at one level in 10 patients,two levels in 13 patients,and three levels in 7 patients. Intervertebral disk hernia at one level in 10 patients,two levels in 15 patients,and three levels in 7 patients. All the patients underwent anterior routecervical discectomy and internal fixation and followed up 10 to 48 months(average 26 months). The effective rate was 87.5%,and the score of evaluation scale for cervical vertigo has improved obviously (from 13.89 to 23.98). Conculsion The curative effect of anterior route cervical discectomy and internal fixation is significant in cervical vertigo.
