The increasing use of more rigid internal fixation constructs for spinal fractures, especially in association with spinal cord injury, has led surgeons to combine sublaminar segmental wiring with Harrington instrumentation systems. Two clinical cases whose neurologic condition deteriorated postoperatively were shown to have sustained direct cord injury by the combination of Harrington compression rods with segmental sublaminar wiring. Myelographic and surgical evidence of hook protrusion into the spinal canal with direct cord injury is presented. Laboratory spine simulations duplicating the clinical situation did demonstrate that sublaminar wiring of the Harrington compression rod system caused the standard hooks to protrude dangerously into the spinal canal. Caution should be exercised not to combine Harrington compression rods with segmental sublaminar wiring.
越来越多地使用更坚固的脊柱骨折内固定结构，尤其是与脊髓损伤相关的情况，促使外科医生将椎板下节段性钢丝固定与哈林顿器械系统相结合。有两个临床病例显示，术后神经状况恶化，原因是哈林顿加压棒与节段性椎板下钢丝固定相结合导致了直接的脊髓损伤。文中展示了脊髓造影和手术证据，表明钩子突出到椎管并造成直接脊髓损伤。模拟临床情况的实验室脊柱实验确实表明，哈林顿加压棒系统的椎板下钢丝固定会导致标准钩子危险地突入椎管。应谨慎操作，避免将哈林顿加压棒与节段性椎板下钢丝固定相结合。
