经皮穿刺椎间盘激光气化减压术联合臭氧注射治疗颈椎病的临床研究

目的探讨经皮穿刺椎间盘激光气化减压术（PLDD）联合臭氧注射治疗颈椎病的临床疗效。方法183例颈椎病患者，随机分两组，PLDD组80例118个椎间盘单纯行PLDD治疗，联合治疗组103例142个椎间盘行PLDD联合臭氧注射治疗，随访3～18个月，平均7个月。采用13本整形外科学会JOA评分表进行对治疗前后功能进行评价，比较两组改善率。结果获随访167例，术后PLDD组平均评分15．2分，改善率74．7％，联合治疗组平均评分16．3分，改善率91．3％，两组比较差异有统计学意义（P〈0．05）。结论PLDD联合臭氧注射治疗颈椎病具有微创、安全、效果好等优点，优于单纯PLDD疗法。

Clinical Study of the treatment of cervical spondylosts with percutaneous laser disc decompression combined with ozone injecaon

Objective To study the clinical effect of percutaneous laser disc decompression(PLDD) combined with ozone injection in the treatment of cervical spondylosis.Methods 183 cases of cervical spondylosis were randomly divided into two groups.One group of 80 cases with 118 cervical discs herniation were treated with PLDDonly.while the other group of 103 cases with 142 cervical discs herniation were treated with PLDD combined with ozone injectlon.The patients were followed up for 3 to18 months(mean 7 months).The clinical effects were assessed according to the Japanese Orthopaedic Association scoring system(JOA score)and the improvement rates of the two groups were compared.Results 167 cases were followed up.The average point of the group treated with PLDD is 15.2 and the improvement rate is 74.7%.The average point of the group treated with PLDD combined with ozone injection is 16.3 and the improvement rate is 91.3%.The difference between two groups has statistical significance(P＜0.05).Conclusion The treatment of cervical spondylosis with PLDD combined with ozone injection is safe.painless and minimally invasive.The clinical effect is impmved tremendously and much better than monotherapy.
