文题释义:
Zero-P颈椎前路内固定:传统经颈前路钢板螺钉内固定术有较多不尽人意之处,如术中出血多,对相关椎体破坏大,钢板应力遮挡增加椎间不融合的概率,术后患者异物感严重难以适应导致术后满意度差等。因此对于脊髓型颈椎病患者,寻求一种较为微创,颈椎融合率高,患者术后满意度高的术式是临床医师的不断努力的目标。
颈椎融合术后的椎体融合:颈椎融合术后最重要的是椎体是否真正融合,对此各位脊柱专家都有研究,有学者尝试过同种异体骨植骨,但是随访显示融合率低;有学者提出异体骨植骨加自身骨髓细胞,这种方法细胞培养费用高,手术疗效不确切且没有长期的随访资料证实其疗效的有效性。传统钢板螺钉内固定术由于钢板应力遮挡,增加了患者颈椎不融合的概率。Zero-P颈椎前路内固定系统具有出血少,风险低,高融合率等特点,可有效恢复颈椎正常生理椎间高度和生理曲度,与人体颈椎具有良好的生物相容性。
 
摘要
背景:Zero-P零切迹颈椎前路内固定系统是近年来治疗脊髓型颈椎病的重要手段,通过Zero-P内固定可实现对脊髓及神经的有效减压,恢复颈椎生理曲度,稳定性良好。
目的:探讨采用Zero-P颈椎前路内固定系统治疗多节段脊髓型颈椎病的生物相容性。
方法:纳入62例采用Zero-P颈椎前路内固定系统治疗的多节段脊髓型颈椎病患者,其中合并2个颈椎节段病变患者47例,3个节段13例,4个节段2例。观察术后1,6,12,24个月颈椎目测类比评分、日本骨科学会(JOA)评分及颈椎功能障碍指数,评价临床疗效;同时观察术后并发症发生率、椎间隙高度及颈椎Cobb角变化。
结果与结论:①54例患者在治疗后2年内通过门诊或电话联系获得随访,平均手术时间(102.00±32.41)min,平均术中出血(62.45±18.36) mL;②2例患者术后1 d出现咽喉轻度不适感,6 d后症状自行解除,其余患者术后各时间点均未出现其他并发症;③术后1,6,12,24个月,患者目测类比评分及颈椎功能障碍指数低于术前(P < 0.05),颈椎JOA评分高于术前(P < 0.05),颈椎Cobb角大于术前(P < 0.05),均较术前明显改善(P < 0.05),术后各时间点病变节段椎间隙高度明显高于术前(P < 0.05);依据JOA评分结果,54例患者中优34例,良14例,可6例,差0例,优良率为89%;④结果表明,Zero-P颈椎前路融合内固定系统治疗多节段颈椎病具有良好效果,可有效缓解患者症状,恢复颈椎生理曲度及高度,具有良好的生物相容性。

Abstract:

BACKGROUND: Zero-P anterior cervical fixation system is an important means for treatment of cervical myelopathy in recent years. Zero-P fixation system can achieve effective decompression of spinal cord and nerve, and restore cervical curvature, with good stability.

OBJECTIVE: To investigate the biocompatibility of Zero-P for multilevel cervical myelopathy.
METHODS: Totally 62 patients with multilevel cervical disease who were treated by anterior cervical discectomy and fusion with Zero-P were selected, including double segments in 47 cases, three segments in 13 cases and four segments in 2 cases. Clinical efficacy was evaluated by pain visual analogue scale score, Japanese Orthopedic Association score, neck disability index score at postoperative 1, 6, 12, 24 months. Simultaneously, incidence of postoperative complications, cervical intervertebral space height and Cobb angle changes were observed.
RESULTS AND CONCLUSION:(1) 54 patients were followed 2 years after treatment by clinic or telephone. Mean operative time was (102.00±32.41) minutes; average blood loss was (62.45±18.36) mL. (2) Two patients affected mild throat discomfort at one day after operation, and the symptoms went to lift six days after. The remaining patients did not experience any other complications. (3) Visual analogue scale score and neck disability index score at 1, 6, 12 and 24 months after operation were all less than preoperatively (P < 0.05); Japanese Orthopedic Association scores were higher than preoperatively (P < 0.05); the Cobb angle was improved significantly and greater than before treatment (P < 0.05). Postoperative cervical intervertebral space height was significantly higher than preoperatively (P < 0.05). Japanese Orthopedic Association results showed that among 54 patients, excellent was found in 34 cases, good in 14 cases, average in 6 cases and poor in 0 cases; the excellent and good rate was 89%. (4) Zero-P has a good clinical efficacy for multilevel cervical myelopathy, relieves symptoms significantly and restores cervical curvature and height, and has a good biocompatibility.
