椎体次全切除植骨融合治疗多平面脊髓型颈椎病

本文报告椎体次全切除植骨融合治疗多平面脊髓型颈椎病15例。术后13例随访4～42个月,其中10例显效或有效。椎体次全切除植骨融合的优点在于:①能直接解除脊髓前方的压迫,不仅限于椎间隙平面,还包括椎体平面,因而减压较为彻底;②植骨不融合的发生率较低;③术野较大,便于在显微镜下操作,可有效地避免直接损伤脊髓和神经根。作者强调手术减压要彻底,植骨融合需稳固。

Subtotal vertebrectomy and spinal fusion for multilevel cervical spondylotic myelopathy

Subtotal vertebrectomy and spinal fusion were carried out in 15 patients with multilevel cervi- cal spondylotic myelopathy.Among 13 patients whom were followed-up for four to fourty-two mo- nths,10 showed marked improvement or improvement.The advantages of subtotal vertebrectomy and spinal fusion were:(1)direct anterior decompression at the disc level as well as body level, (2)low rate of nonunion of bone graft and(3)wider operative field allowing the use of surgical microscope and avoiding the damage to spinal cord and nerve roots.Two points were emphasized during operation:decompression of spinal cord should be complete and the bone graft should be inserted firmly.
