【摘要】 目的:評(píng)估C3~6單開門椎板成形術(shù)治療多節(jié)段脊髓型頸椎病的效果。方法:回顧性分析2014年1月-2017年7月行后路C3~6單開門頸椎板成形術(shù)的17例多節(jié)段脊髓型頸椎病患者的臨床資料。比較手術(shù)前后日本骨科協(xié)會(huì)(JOA)評(píng)分、頸椎前凸角度、頸椎曲度指數(shù)、脊髓向后漂移距離。觀察術(shù)后頸椎軸性癥狀及不良事件發(fā)生情況。結(jié)果:術(shù)后隨訪12~50個(gè)月,平均隨訪18個(gè)月。術(shù)后12個(gè)月JOA評(píng)分、頸椎前凸角度、頸椎曲度指數(shù)、脊髓向后漂移距離與術(shù)前比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.01)。術(shù)后無頸椎軸性癥狀發(fā)生。術(shù)后無C5神經(jīng)根麻痹,無腦脊液漏及內(nèi)置物斷裂等不良事件發(fā)生。結(jié)論:C3~6單開門椎板成形術(shù)能夠使頸脊髓向后漂移,改善神經(jīng)功能,降低術(shù)后軸性癥狀發(fā)生。

C3-6 Single Open-door Laminoplasty in the Treatment of Multilevel Cervical Spondylotic Myelopathy/CHENG Jun, YAN Kui. //Chinese and Foreign Medical Research, 2020, 18(16): -36
[Abstract] Objective: To evaluate the effect of C3-6 single open-door laminoplasty in the treatment of multilevel cervical spondylotic myelopathy. Method: The clinical data of 17 patients with multilevel cervical spondylotic myelopathy who underwent C3~6 single open-door laminoplasty from January 2014 to July 2017 were retrospectively analyzed. The Japanese orthopaedic association (JOA) score, cervical lordosis angle, cervical curvature index, and spinal cord backward drift distance before and after surgery were compared. Postoperative cervical axial symptoms and adverse events were observed. Result: Postoperative follow-up ranged from 12 to 50 months, with an average follow-up of 18 months. The JOA score, cervical lordosis angle, cervical curvature index, and spinal cord backward drift distance at 12 months after surgery showed statistically significant differences compared with those before surgery (P<0.01). There was no cervical axial symptom after surgery. There were no C5 nerve root paralysis, no cerebrospinal fluid leakage, no internal material fracture and other adverse events after surgery. Conclusion: C3-6 single open-door laminoplasty can cause the cervical spinal cord backward drift, improve nerve function, and reduce the occurrence of postoperative cervical axial symptom.

頸椎單開門椎板成形術(shù)的主要機(jī)制是將脊髓壓迫通過椎管擴(kuò)張解除,而消除脊髓神經(jīng)阻礙,提升其功能。由于創(chuàng)傷小,可用于老年患者多節(jié)段頸椎間盤突出癥、頸椎管狹窄癥、后縱韌帶骨化等頸椎病的治療。通過多個(gè)椎板成形,保留頸椎活動(dòng)范圍,維持頸椎生理曲度。但也有研究發(fā)現(xiàn),采用C3~7椎板成形術(shù)破壞后方韌帶肌肉結(jié)構(gòu),特別是C2和C7棘突止點(diǎn)的破壞,可加重術(shù)后頸部軸性痛,降低頸椎活動(dòng)范圍[1]。2014年1月-2017年7月筆者所在科采用C3~6單開門椎板成形術(shù)治療多節(jié)段脊髓型頸椎病17例,現(xiàn)報(bào)道如下。

1.1 一般資料
回顧性分析2014年1月-2017年7月行后路C3~6單開門頸椎板成形術(shù)的17例多節(jié)段脊髓型頸椎病患者的臨床資料。納入標(biāo)準(zhǔn):(1)術(shù)前存在頸脊髓受壓表現(xiàn),肢體無法正常支撐或完全喪失活動(dòng)能力,肌張力擴(kuò)張、健反射亢進(jìn)及病理征陽性,臨床常規(guī)治療3個(gè)月無效;(2)影像學(xué)檢查C3~6脊髓受壓。……
