Cervical instability secondary to fracture/dislocation or traumatic subluxation involving the posterior elements may be treated by a variety of fusion techniques. The rigidity of the stainless steel wires used in posterior cervical fusions often leads to difficulty with insertion, adequate tension, and conformation of the graft construct. This report describes a technique of posterior cervical fusion employing a wire system using flexible stainless steel cables. The wire consists of a flexible, 49-strand, stainless steel cable connected on one end to a short, malleable, blunt leader with the opposite end connected to a small islet. The cable may be used in occipitocervical, atlantoaxial, facet-to-spinous process, and interspinous fusion techniques. The cable loop is secured by using a tension/crimper device that sets the desired tension in the cable. In addition to superior biomechanical strength, the flexibility of the cable allows greater ease of insertion and tension adjustment. In terms of direct operative instrumentation in posterior cervical arthrodesis, involving both the upper and lower cervical spine, the cable system appears to be a safe and efficient alternative to monofilament wires.
继发于骨折/脱位或累及后部结构的创伤性半脱位的颈椎不稳，可通过多种融合技术进行治疗。颈椎后路融合术中使用的不锈钢丝的刚性常常导致植入困难、难以施加足够的张力以及移植物结构的塑形。本报告描述了一种采用柔性不锈钢缆线的钢丝系统进行颈椎后路融合的技术。该钢丝由一根柔性的、49股不锈钢缆线组成，一端连接到一个短的、可锻造的钝头导针，另一端连接到一个小的岛状物。该缆线可用于枕颈、寰枢椎、关节突至棘突以及棘突间融合技术。通过使用一种张力/压接装置来固定缆线环，该装置可设定缆线所需的张力。除了具有卓越的生物力学强度外，缆线的柔韧性还使植入和张力调整更加容易。就涉及上颈椎和下颈椎的颈椎后路关节融合术中的直接手术器械而言，缆线系统似乎是单丝钢丝的一种安全且有效的替代方案。
