A Study of the Anatomical Features of Lumbosacral Nerve Roots in Epidural Space

Objective:To investigate the anatomical features of lumbosacral nerve roots in epidural space to provide the anatomical bsais for selective posterior rhizotomy (SPR).Methods:Microdissection and measurement were performed on lumbosacral nerve roots of 12 adults fixed and 4 fresh children cadavers.Results:The length of lumbosacral nerve roots in epidural space is short and extremely difficult to be exposed. Conclusion: SPR in epidural space, the operation put forward theoretically is extremely difficult,so it can′t be performed without careful consideration.
