We reviewed the records of 28 patients with 30 burst-dispersion spinal fractures treated since the introduction of CT facilities in Western Australia. Twenty-five patients showed spinal canal deformity and stenosis with bone fragments protruding into the canal on the initial scan. Of these, 22 patients were treated nonsurgically. Fifteen of the conservatively treated patients were available for follow-up, and they form the basis of this report. Thirteen of the 15 patients who had repeat CT at follow-up showed correction of the previously measured spinal canal stenosis by spontaneous resorption of intraspinal bone fragments. In view of this previously unreported finding, it is suggested that the role of surgical correction of spinal canal stenosis resulting from displaced bone fragments after trauma be more clearly defined.
我们回顾了西澳大利亚引入CT设备后接受治疗的28例患者的30处爆裂性分散型脊柱骨折记录。25例患者在初次扫描时显示椎管畸形和狭窄，有骨碎片突入椎管。其中，22例患者接受了非手术治疗。15例接受保守治疗的患者可供随访，他们构成了本报告的基础。15例在随访时进行重复CT检查的患者中，有13例显示椎管狭窄通过椎管内骨碎片的自发吸收得到了纠正，这是之前未报道过的发现。鉴于此，建议更明确地界定创伤后移位骨碎片导致椎管狭窄的手术矫正作用。
