Kümmell病的临床研究进展

Clinical research progress in Kummell disease

摘要:

Kümmell 病是一种脊柱轻微外伤后的椎体压缩骨折不愈合, 目前发病机制尚不明确, 可能是椎体缺血性坏死和椎体内假关节形成等多种因素相互作用所致。主要的临床表现为迟发性的慢性腰背痛, 影像学特征为椎体塌陷和真空裂隙征。对于 I、 II 期 Kümmell 病经皮椎体成形术和经皮椎体后凸成形能够取得良好效果，III 期 Kümmell 病更倾向于开放手术，但根据病情手术入路的选择有所不同。

Abstract:

Kümmell’s disease is a nonunion of vertebral body compression fractures after minor spinal trauma with unclear pathogene- sis. It may be caused by the interaction of multiple factors, such as avascular necrosis of the vertebral body and the formation of pseudoarthro- sis in the vertebral body. The main clinical manifestation of Kümmell’s disease is delayed chronic low back pain, while the imaging feature is vertebral body collapse with vacuum fissure sign. For stage I and II Kümmell’s disease percutaneous vertebroplasty and percutaneous kypho- plasty have been proved good results. For stage III Kümmell’s disease, open surgery is preferred , however, the choice of surgical approaches varies according to the patient’s condition.
