The past several decades have been the setting for a remarkable evolution of spinal instrumentation technology. The advancements that have been made have allowed previously complex disorders of the cervical spine, the atlantoaxial articulation, and the occipitocervical junction to be managed more effectively with direct methods of internal fixation and arthrodesis. This has resulted in improvements in patient outcomes and fusion success rates. The improved strength of instrumentation constructs allows minimal, if any, external bracing, obviating the need for a halo orthosis in many cases. In this paper the authors review key events that have occurred in neuroimaging, biomechanical testing, and the development of fusion and instrumentation constructs.
在过去几十年里,脊柱内固定技术经历了显著的发展。这些进步使得以前复杂的颈椎、寰枢关节和枕颈交界区疾病能够通过直接的内固定和关节融合术得到更有效的治疗。这带来了患者治疗效果和融合成功率的提高。器械结构强度的提高使得在许多情况下即使需要也只需极少的外部支撑,从而无需使用头环支具。在本文中,作者回顾了神经影像学、生物力学测试以及融合和器械结构发展过程中发生的关键事件。
