摘　　要：目的：探讨5.12汶川大地震致脊椎外伤伤员的影像学表现特点。方法：回顾性分析自2008年5月12日至6月12日因地震性脊柱外伤在我院行放射检查者,共320例。其中行X线检查310例,CT检查38例,MRI检查15例。结果：148例伤员影像学检查为阳性,阳性率为46.25%。30-39岁年龄组伤员人数最多,为68例,其中女性40例。阳性伤员中,多发伤有80例（54.05%）。单一椎体骨折98例,多发椎体骨折42例,椎体脱位12例。椎体压缩骨折114个,爆裂骨折26个,附件骨折31个。310例伤员中,共累及182个椎体,即颈椎15个,胸椎59个,腰椎100个,骶椎8个。结论：地震致脊椎外伤受累人群主要为30-39岁青年女性,多发伤多见。单一椎体骨折相对多见,骨折损伤类型以压缩性骨折为主,腰椎为最常见受伤部位。影像学检查有助于脊柱外伤的及时准确诊断。Objective：To explore the imaging features of vertebral injury patients after the Wenchuan earthquake.Methods：The radiological information of 320 victims who were suspicious of vertebral injury and underwent radiological examinations from 12 May to 12 June 2008 was analysed retrospectively.There were 310 patients underwent X-ray plain film examination,38 patients underwent CT,15 patients underwent MRI examinations respectively.Results：Results of 148 patients were positive,with a positive rate of 46.25%.There were 68 patients in 30-39 years old age group,of which 40 were female.In patients with positive findings,80 cases（54.05%） were comprised of several types of injury.There were 98 cases of single-level vertebral fracture,42 cases of multiple-level vertebral fracture,12 cases of vertebral dislocation.One hundred and forteen vertebrae were diagnosed as compression fracture,26 vertebrae as bursting fracture and 31 vertebrae as vertebral appendix fracture.Totally 182 vertebrae were involved,of which 15 were cervical vertebrae,59 thoracic vertebrae,100 lumbar vertebrae and 8 sacral vertebrae.Conclusion：The females with vertebral injury in 30-39 years old are the major injured people in this earthquake.Polytraumatized cases are common.Single-level vertebral fracture and compression fracture are relatively common.Lumbar vertebral is the most inflicted place in this disaster.Imaging examination is helpful in the diagnosis of vertebral injury in the earthquake.
