摘要:

背景:钛网是近年来国内外应用于脊柱尤其是颈椎疾患的一种常用新型植骨支撑物,目前脊髓型颈椎病患者的前路手术中如何更好地改善颈椎前凸弧度仍是治疗的难点。
目的:观察脊髓型颈椎病患者经颈前路椎体次全切过程中,直形钛网与个体化设计钛网植骨融合内固定对颈椎曲度恢复及治疗后JOA评分的影响。
方法:纳入43例有椎体次全切、减压植骨内固定手术指征的脊髓型颈椎病患者,根据治疗内固定方案分为2组,个体化设计梯形钛网组15例,直形钛网组28例。所有患者于治疗前均拍摄颈椎正侧位X射线片作为空白对照。回顾2组患者的临床资料,比较治疗后JOA评分、颈椎弧度、椎间角度及椎间高度的差异。
结果与结论:颈椎前凸角度、手术节段椎间角度方面,个性化钛网组较直形钛网组和空白对照组显著改善(P < 0.01),直形钛网组亦较空白对照组有改善(P < 0.05)。手术节段椎间高度方面,个性化钛网组与直形钛网组较空白对照组分别增加了3.69 mm和3.22 mm,而个性化钛网组与直形钛网组之间差异无显著性意义(P > 0.05)。JOA评分方面,个性化钛网组与直形钛网组患者各时间段差异无显著性意义(P > 0.05)。提示在脊髓型颈椎病患者行椎体次全切时,修剪钛网以模拟正常椎间盘前高后低的形状,可以更有效地恢复颈椎生理弧度和手术节段椎间角度。

Abstract:

BACKGROUND: Titanium mesh is a new type of bone graft supports used for the treatment of spine, especially the cervical spine disorders at home and abroad in recent years. But, at present, how to improve the cervical lordosis curvature during anterior surgery is the difficulty for the treatment of cervical spondylotic myelopathy. 
OBJECTIVE: To observe the effect of straight titanium mesh and individual designed titanium mesh used in the bone graft fusion and internal fixation on the recovery of cervical curvature and Japanese Orthopaedic Association score during anterior cervical subtotal vertebrectomy in the patients with cervical spondylotic myelopathy.  
METHODS: Forty-three patients with cervical spondylotic myelopathy treated with surgical indications of subtotal vertebrectomy and decompression internal fixation were included, and the patients were divided into two groups according to different internal fixation methods. There were 15 cases in the individual designed titanium mesh group and 28 cases in the straight titanium mesh group. The preoperative anteroposterior X-ray films of the cervical spine of all the patients were as the blank control group. The clinical data of the patients in two groups were retrospectively analyzed, and the postoperative Japanese Orthopaedic Association score, cervical curvature, intervertebral angles and intervertebral height were compared.
RESULTS AND CONCLUSION: The cervical lordosis angle and the intervertebral angle of surgery segment in the individual designed titanium mesh group were improved when compared with those in the straight titanium mesh group and the blank control group (P < 0.01), and the straight titanium mesh group was better than the blank control group (P < 0.05). The intervertebral height of surgery segment in the individual designed titanium mesh group and the straight titanium mesh group was increased for 3.69 mm and 3.22 mm respectively when compared with that in the blank control group, and there was significant difference between individual designed titanium mesh group and the straight titanium mesh group (P > 0.05). There was no significant difference in Japanese Orthopaedic Association score between individual designed titanium mesh group and the straight titanium mesh group (P > 0.05). During subtotal vertebrectomy for the treatment of cervical spondylotic myelopathy, cutting titanium mesh into trapezoidal shape to simulate the normal disc shape of former high to low can effectively restore the physiological curvature of cervical spine and the intervertebral height of surgery segment.
