腰椎変性疾患におけるCDI法の検討 -その合併症について-

抄録

We reviewed 27 cases who underwent Cotrel-Dubousset Instrumentation (CDI) for lumbar degenerative disorders and studied the major complications encountered. Intra-operative complications experienced were pedicular fractures in 2 cases, post-operative complications were local infection, non-union of the grafted bone, instrument failure, and decubitus at the screw head in 1, 4, 6, and 1 case, respectively. To avoid these complications, it is important to restrict the indication for using instrumentation in lumbar degenerative disorders and to develop good surgical techniques.
