颈前路椎体次全切钛网植骨钛网裁切技术探讨

目的探讨颈椎前路椎体次全切除减压钛网植骨钢板内固定患者术中钛网修剪的技巧以获得更好的接触面.方法47例脊髓型颈椎病患者,病变累及单间隙7例,双间隙40例,行前路椎体次全切除减压钛网植骨并辅以O-rion钢板内固定.术中根据钛网结构和所需长度进行设计,采用四种不同的方法进行剪切.结果47例中43例获6～18月随访,植骨均在12周达到临床愈合,未见钛网下沉、颈椎椎间高度及曲度改变.结论通过针对不同长度的特殊设计和钛网剪切,增加钛网接触面积,可以减少因接触面原因导致的钛网下沉.

Discussion of titanium mesh cutting technique in anterior cervical corpectomy surgery

Objective Discuss the technique for titanium mesh cutting to attain maximum contacting surface in anterior cervical corpectomy with titanium mesh graft and locking plate fixation surgery. Method 47 cases of cervical spondylosis myelopathy were studied among which 40 cases involved two intervertebral discs and 6 cases with one level. All cases were treated with anterior corpectomy and implanted with titanium mesh filled with cancellous bone of resected vertebra body combine with Orion anterior plates. The titanium meshes were cut by four different ways by the design related with the length and titanium structure. Result 43 of 47 patients were followed up to 6 to 18 months. Solid fusion of the titanium mesh was obtained within 12 weeks. No case of intervertebral height and cervical lordosis lose, titanium mesh subsidence was found in this group. Conclusion The possibility of titanium mesh subsidence caused by the contact surface may be reduced by increasing the surface contact area of the implant through identical design and titanium mesh cutting for each different length.
