目的 了解单开门颈椎椎管扩大成型术治疗颈椎椎管狭窄症的远期效果。方法 对９８例颈椎椎管狭窄症患者施行了单开门颈椎椎管扩大成型术，其中６１例获得随访，平均随访１１年８个月。结果 颈椎后纵韧带骨化症（ＯＰＬＬ）组３２例，发育性颈椎椎管狭窄（ＤＣＳ）组２０例脊髓型颈椎病（ＣＳＭ）组８例，三组均在术后３年时疗效最佳，ＪＯＡ评分平均改善率分别为７２．３０％～６７．８％和（ＣＳＭ）组８例，三组均在术后３年时疗

Long term Results of Expansive Open door Laminoplasty of Cervical Spine

Objective To observe the long term results of expansive open door laminoplasty of cervical spine for cervical spinal stenotic myelopathy.Methods From April 1986 to March 1988, 98 cases were operated upon with expansive open door laminoplasty of cervical spine. Sixty one cases had been followed up for an average of 11 years and 8 months. The long term results were analyzed.Results The best results were obtained at the third year after operation among the OPLL (32 cases),DCS (20 cases) and CSM (8 cases),with an average JOA recovery rate for an average of 72.30%in OPLL, 67.74%in DCS and 67.80%in CSM. JOA recovery rate were 66.81%in OPLL, 66.57%in DCS and 66.1%in CSM at following up for an average of 11 years and 8 months. Instability of the cervical spine and reclosed open door were not found at the follow up for an average of 11 years and 8 months.Conclusion The long term results of expansive open door laminoplasty of cervical spine for cervical spinal myelopathy were good and stable. Expansive open door laminoplasty of cervical spine did not affect the stability of cervical spine.;
