成人退行性脊柱侧凸矫形术后发生融合节段近端交界性后凸的研究进展

Research progress in proximal junctional kyphosis after orthopedic surgery of adult degenerative scoliosis

成人脊柱畸形(adult spinal deformity,ASD)矫形往往需要长节段固定,然而长节段固定融合节段的刚性差别以及交界区域内的应力集中,容易导致固定近端出现交界性后凸畸形(proximal junctional kyphosis,PJK)或者近端交界区失败(proximal junctional failure,PJF)[1~3]。
