"Standard", noninstrumented, techniques of anterior interbody fusion are frequently followed by nonunion and collapse of the intervertebral space, probably because of persistent rocking movements, particularly in the sagittal plane. Elimination of these theoretical movements by supplementing an anterior interbody fusion with a posterior interspinous H-graft and a cerclage wire was considered to be biomechanically attractive without having the disadvantages associated with posterior instrumentation. In a prospective study a solid fusion was obtained at 16 of 17 operated levels, with a mediocre (+/- 50%) fusion as the exception. The height of the intervertebral space was increased at the majority of the fused levels. The technique is only applicable where neural arches are intact. The technique proved to be safe, simple, effective and inexpensive.
“标准”的非器械辅助前路椎间融合技术常常会导致椎间融合失败和椎间隙塌陷，这可能是由于持续的摇摆运动，尤其是矢状面的运动。通过后路棘突间H形植骨和环扎钢丝辅助前路椎间融合来消除这些理论上的运动，在生物力学上颇具吸引力，且没有后路器械辅助的缺点。在一项前瞻性研究中，17个手术节段中有16个实现了坚固融合，仅有一个节段融合效果一般（±50%）。大多数融合节段的椎间隙高度增加。该技术仅适用于神经弓完整的情况。该技术被证明是安全、简单、有效且经济的。
