BACKGROUND
Harrington rods and more modern thoracolumbar posterior fusion with segmental instrumentation have been used successfully for decades in individuals with scoliosis or spinal cord injury (SCI). However, late complications of these instrumentations specifically presenting as new, localized pain in individuals with SCI have not been previously reported. Displacement of the hooks and the rods can cause significant back pain that may require hardware removal.
METHODS
Two case reports illustrate thoracolumbar fusion rod removal because of displaced hooks with protruding rods and associated pain.
RESULTS
Both of the individuals experienced back pain caused by proximal hook displacement. There was no neurologic deterioration. The proximal portions of the rods were sawed off and the displaced hooks and the rods were removed.
CONCLUSIONS
These cases illustrate the importance of clarifying different types of pain experienced by individuals with SCI and the importance of diagnosing the cause of pain accurately.
背景
哈灵顿棒以及更现代的节段性器械辅助胸腰椎后路融合术已成功应用于脊柱侧弯或脊髓损伤（SCI）患者数十年。然而，这些器械的晚期并发症，特别是在SCI患者中表现为新出现的局部疼痛，此前尚未见报道。钩和棒的移位可导致严重的背痛，可能需要取出内固定装置。
方法
两例病例报告阐述了因钩移位、棒突出及相关疼痛而进行胸腰椎融合棒取出术的情况。
结果
两名患者均因近端钩移位而出现背痛。均无神经功能恶化。锯断棒的近端部分，取出移位的钩和棒。
结论
这些病例说明了明确SCI患者所经历的不同类型疼痛的重要性以及准确诊断疼痛原因的重要性。
