颈椎后路单开门加双侧短节段侧块内固定术治疗颈椎病伴颈椎失稳

Treatment of Cervical Spondylotic with Instability of Cervical Vertebrate Using Short-segmental Bilateral Mass Fixation with Posterior Route Unilateral Open-door Laminoplasty

评估颈椎后路单开门减压椎管扩大成形术加双侧短节段侧块内固定术在治疗颈椎病伴颈椎失稳中的应用价值．回顾分析近4年应用此方法治疗颈椎病伴颈椎失稳患者28例，术后平均随访13个月，并根据手术前后JOA来评分和影像改变评价手术的优缺点．发现术后临床症状明显改善，JOA评分平均提高4～7分．应用颈椎后路单开门减压椎管扩大成形术加双侧短节段侧块内固定术既能实现减压，又重建稳定，较好地维持颈椎生理前凸，无明显的术后僵硬与不适，是治疗多种颈椎病合并颈椎不稳的一种较好的方法．

To evaluate the clinic effect of the short-segmental bilateral mass fixation for posterior route unilateral opendoor laminoplasty in the treatment of cervical spondylotic with instability of cervical vertebrate, 28 cases with cervical spondylotic unstability are reviewed and followed up for 13 months in the past 4 years. We evaluated the operation types based on the JOA score and images which we obtained at both pre-and-post operation stages. Clinic symptoms were improved after operation and JOA score increased about 4-7 points. Short-segmental bilateral mass fixation for posterior route unilateral open-door laminoplasty proves to be a safe and effective operation choice in curing cervical spondylotic unstability. Not only can it decrease the pressure but also can increase the stability after operation and maintain the natural arc of cervical spine, and decrease the ankylosis and discomfort of cervical spine. It is a good method to treat cervical spondylotic and instability of cervical vertebrate.
