老年人脊髓型颈椎病的特点

目的：探讨老年人脊髓型颈椎病的临床特点，以及年龄对脊髓型颈椎病的预后影响。方法：回顾性对比分析564例脊髓型颈椎病，其中老年患者191例，占33．9％，非老年患者373例。术后随访2～10年，平均5年3个月。结果：老年组中发育性椎管狭窄（x^24．78，P〈0．05、合并退变性椎管狭窄高于非老年组（x^2=49．07，P〈0．01），有效率（x^2=5．03，P〈0．05）、优良率（x^2=6．5，P〈0．05）低于非老年组。结论：老年人脊髓型颈椎病预后差。

The Clinical Characteristics of Cervical Spondylotic Myelopathy in the Old Patients

Objective： To study the clinical characteristics of cervical spondylotic myelopathy （CSM） in the aged patients and the influence of age on the prognosis. Methods： 564 patients with CSM were retrospectively analyzed. Among them, 191 patients were older than 60 years old （33.9%） and 373 patients were younger than 59 years old. All patients were followed-up for 2-10 years after operations （average 5 years and 3 months）. Results： In the older group, the rate of the developmental spinal stenosis （x^2=4.78, P〈0.05） and degenerative spinal stenosis （x^2=49.07, P〈0.01） was higher than that in the younger group, and the effective rate （x^2=5.03, P〈0.05） and good rate （x^2=6.5, P〈0.05） were lower than that in the younger group. Conclusion： The old patients with CSM usually have a poor prognosis.
