胸腰段爆裂骨折椎管损伤CT研究及临床意义

CT Imaging of Spinal Canal Injuries and Clinical Significane in Thoracolumbar Burst Fracture

目的：通过观察爆裂骨折ＣＴ影像及椎管损伤程度，探讨手术治疗方式。方法：本组８９例胸腰段爆裂骨折病人术前常规进行Ｘ线、ＣＴ检查，观察影像与临床关系。其中手术治疗７７例，保守治疗１２例。结果：（１）骨片突入椎管诊断ＣＴ高于普通Ｘ线。（２）ＣＴ观察椎管内骨片大小、形态与神经损伤没有相关性（ｒ＝０１４，Ｐ＞００５）。（３）分５型及相关亚型。结论：能对椎管损伤准确诊断。

Objective:To select method of surgical treatment for thoracolumbar burst fraction based on the degree of displacement of spinal canal in CT imaging.Method:CT scan measurements of spinal canal diameter and plain roentgenogram were performed in 89 patients with thoracolumbar burst fracture preoperatively to observe correlation between imaging and clinical finding.Of the patients,77 cases were treated surgically and 12 cases conservatively.Results:(1) CT diagnosis was higher precise than plain roentgenogram.(2) CT finding was not correlated to the neurological injury(r=0 14, P >0 05).(3) the pattern of the spinl canal injury were divided into five types and related subgroups.Conclusion:It can indicate clinical changes and guide the diagnosis.The classifications guide the selection of surgical approaches.
