摘要从脊髓前方压迫引起的胸椎管狭窄(thoracic spinal stenosis,TSS)的原因有胸椎间盘突出(thoracic disc herniation,TDH)、胸椎后纵韧带骨化(ossification of the posterior longitudinal ligament,OPLL)、胸椎后缘骨赘等,临床症状凶险且呈进行性加重,保守治疗效果不佳,目前认为手术是唯一有效的治疗方法,但因操作难度大,易出现脊髓损伤甚至瘫痪等严重术后并发症,尽管治疗TSS的手术技术不断进步,但标准手术方式仍未有定论。我们收治1例OPLL胸椎管狭窄症的患者,采用一种新的后路改良术式即经硬膜入路环形减压内固定术治疗,术后随访12个月,疗效满意,现报告如下。
