文题释义:
颈椎后路椎管扩大成形术:颈椎病主要是脊髓和/或神经根受原发性或继发性压迫,椎管或神经根管狭窄所致。而通过颈椎后路单侧或双侧切开椎板,使椎板向后外侧移位,以扩大椎管容积,使脊髓神经向后漂移,间接消除脊髓压迫。颈椎后路椎管扩大成形术具有对颈椎的稳定性破坏小,并发症少,保留了颈椎的稳定性及活动度,且相邻节段不需要融合。
颈椎矢状面参数:正常的颈椎序列对于维持颈椎的生物力学特性及及正常运动功能起决定性作用。因此,恢复颈椎的矢状面序列成为制定术前手术方案和评价术后效果的关键。评估颈椎矢状面序列常用的参数主要有C2-7 Cobb角、C2-7矢状面轴向距离、C7倾斜角及T1倾斜角等。
 
摘要
背景:颈椎后路单开门椎管扩大成形术是治疗颈椎疾患的良好术式,具有临床疗效确切,操作相对简单,以及并发症少等优点。然而单开门术后颈椎矢状面失衡,前凸角度丢失或轴性痛等的报道并不少见。
目的:探讨颈椎后路单开门椎管扩大成形微型钛板置入的疗效与矢状面参数变化之间的关系。
方法:回顾性分析2011年1月至2015年6月采用单开门椎管扩大成形微型钛板置入治疗的122例颈椎疾患病例,利用日本骨科协会(JOA)评分、颈椎功能障碍指数及疼痛目测类比评分评估临床疗效;利用C2-7 Cobb角、C2-7矢状面轴向距离及C7倾斜角评估影像学效果;并探讨临床修复效果与影像学参数变化之间的相关性。
结果与结论:①所有患者均获得随访,随访时间7-32个月;②末次随访时JOA评分、颈椎功能障碍指数及颈部目测类比评分均较术前明显改善(P均< 0.001),而上肢目测类比评分无明显变化(P=0.142)。末次随访时C2-7矢状面轴向距离较术前增加(P=0.036);而C2-7前凸角及C7倾斜角与术前相比无明显变化(P=0.092,P=0.184);③C2-7 Cobb角、C2-7矢状面轴向距离及C7倾斜角等颈椎矢状位参数的变化与临床指标JOA评分、颈椎功能障碍指数及目测类比评分的改善并无明显相关性(P均> 0.05);④结果提示,颈椎后路单开门椎管扩大成形微型钛板置入治疗能显著改善患者的神经功能,然而术后颈椎矢状面参数变化与疗效提高并无明显相关性。

Abstract:

BACKGROUND: Posterior cervical open-door expansive laminoplasty is one of the simple and effective methods to treat cervical spinal diseases, has satisfactory results but low complications. However, the imbalance of sagittal plan, loss of lordosis or axial pain is often reported recently.   

OBJECTVE: To analyze the correlation between cervical sagittal alignment and clinical outcomes after laminoplasty.
METHODS: Between January 2011 and June 2015, 122 cases of cervical spinal disease, who were treated with open-door expansive laminoplasty with mini-titanium plate, were retrospectively analyzed. Clinical outcomes were evaluated by Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale. Radiographic results were assessed by C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope. The correlation between sagittal alignment and clinical outcomes were analyzed.
RESULTS AND CONCLUSION: (1) All patients were followed up for 7-32 months. (2) Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale scores were improved in the final follow-up (all P < 0.001). No significant difference in upper limb Visual Analogue Scale scores was determined (P=0.142). In the final follow-up, C2-7 sagittal vertical axis increased (P=0.036), but neither the C2-7 Cobb angle nor the C7 slope significantly changed (P=0.092, P=0.184). (3) There were no correlations between sagittal alignment parameters (C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope) and clinical outcomes (Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale) (all P > 0.05). (4) These findings indicated that posterior cervical open-door expansive laminoplasty with mini-titanium plate can significantly improve the neurological function of patients. However, there is no correlation between cervical sagittal alignment and clinical outcomes.
