脊柱畸形术后近端交界性后凸的研究现状

Research status of proximal junctional kyphosis after scoliosis surgery

青少年脊柱畸形矫形手术的目的是矫正畸形,而对于成人脊柱侧凸患者来讲,由于多合并有躯干的失平衡,重建脊柱平衡显得尤为重要[1],尤其以矢状面平衡重建的意义更为重要。近年来,随着后路矫形器械的发展和保留脊柱运动节段的需要,骨科医师越来越多地采取选择性后路节段性融合的手术策略,在取得良好临床疗效的同时[2],术后融合节段近端交界性后凸（proximal junctional kyphosis,PJK）和近端交界性失败（proximal

With the development of surgery skills in spine, posterior selective fusion of the spine segments can achieve good clinical outcomes. However, proximal junctional kyphosis（ PJK） and poximal junctional failure（ PJF） are common complications after spine deformity surgery. By reviewing relevant literatures comprehensively, PJK and PJF are elaborated in detail including the definition, pathogenetic mechanism, risk factors, prevention and classifications. It will be helpful for surgeons to schedule treatment plan and reduce the incidence of the PJK and PJF.
