颈椎后路单开门椎管扩大成形术后轴性症状的研究进展

Research progress on axial symptoms of cervical posterior open-door laminoplasty

颈椎后路椎管扩大成形术是治疗多节段脊髓型颈椎病、发育性/退变性颈椎管狭窄、颈椎后纵韧带骨化症的经典术式,手术近远期疗效好。但是有些患者在手术后可以出现轴性症状,并且发病率高,严重时会影响患者的生活和工作。术后轴性症状发生的确切机制尚不完全清楚,目前认为主要和颈椎后伸机制的破坏及颈椎活动度的减少有关。目前对轴性症状的治疗尚无特效方法,大部分学者通过对传统颈后路单开门椎管扩大成形术进行改良来减少轴性症状的发生。

Laminoplasty is a classic surgical procedure which has achieved good efficiency in both short-term and long-term fellow-up result in the treatment of multi-segment cervical spondylotic myelopathy,developmental cervical spinal canal,degenerative cervical spinal canal stenosis and ossification of the posterior longitudinal ligament. However, many patients who were procedured cervical spine surgery emerge the complication of axial symptom and the rate of this complication is very high.The serious axial symptom will affect the patient＇s life and work.Although the precise pathological meehanism of axial symptoms is unclear yet,most of surgeons consider that it is related to the damage of cervical extension mechanism and the decrease of range of motion of cervical spine.There is no efficient treatment for axial symptom nowadays,so most of researchers reduce the incidence of this complication by improving the traditional laminoplasty.
