Intrasacral Fixation (ISF) を用いた腰仙椎部固定について

抄録

We operated on cases of degenerative lumbosacral kyphosis by use of the Isola-galveston method. However, correction of pelvic posterior rotation was unsatisfactory and instrumentation failure occurred. Two years ago, we introduced posterior wedge vertebral osteotomy in which shortening and fixture by the intrasacral fixation (ISF) method are performed. We operated on 6 cases by this method. At follow-up (mean: 11 months), the cases showed remarkabe improvement of the clinical symptoms and good correction of the lumbosacral alignment. This method was found to reasonably correct flat backs and maintain correction during follow-up.
