Posterior-anterior approach surgical treatment for severe cervical spondylotic myelopathy / 中国矫形外科杂志

ABSTRACT

[Objective]To explore the therapeutic effect of the posterior-anterior approach surgical treatment for severe cervical spondylotic myelopathy.[Method]Totally 32 patients with severe cervical spondylotic myelopathy operated by posterior-anterior approach surgical treatment from September in 1998 to January in 2005 were retrospectively analyzed.In the 32 patients,20 males and 12 females.Their age averaged 53.8 years(ranged,41~78 years),invasional segmentsC3、42 cases,C4、5 9 cases,C5、611 cases,C6、7 10 cases.Four cases with lesions involving one intervenebral space,the other 12 and 16 cases involving two and three intervertebral spaces respectively.All cases had the posterior cervical open-door laminoplasty decompression in first,and had the anterior cervical decompression and bone grafting or fusion with titanium Cage internal fixation after a week.To follow up all the postoperative cases,neural function was recorded.According to JOA score,preoperative score and postoperative follow-up score were compared,improvement rates were caleulated respectively.[Result]All cases were regularly followed up.The duration of follow-up averaged 13.6 months(ranged,12~18 months).The JOA of before operation was(6.51?1.10),the JOA of first period of time after operation was(9.47?0.5),and follow-up JOA was(12.42?0.79).T-test was used to compare pre-operative and follow-up JOA scores.The statistical results were significantly different(P
