目的 探讨无骨折脱位型颈脊髓损伤的实质。方法 54例无骨折脱位颈脊髓损伤,分析其MRI表现。采取摘除突出椎间盘或/和清除椎管后方致压物、扩大椎管的手术治疗,随访其术后疗效。结果 MRI显示外伤性颈椎间盘突出为主,同一节段黄韧带、棘间和棘上韧带等软组织损伤,导致脊髓压迫、挤压性损害。术后54例病人都有不同程度的康复。结论 外伤引起的颈椎间盘突出挤压脊髓和一过性损伤是无骨折脱位颈脊髓损伤的主要原因。
Objective For the essence of the cervical cord injury without fracture and disloction . Methods 54 cases with traumatic cervical cord injury without fracture and disloction on X ?ray films were reported. They were revealed that of the patients with traumatic cervical herniated disc in mainly, and flavum ligament, interspinal ligament and supraspinal ligament injury in same level segmant were showed on MRI. Result The cervical cord lesion was presented on the compression and crushed by the herniated disc on MRI. Anterior decompression, enlargeing the cervical stenosis were performed.
