Musculoskeletal ImagingPosterior lumbar interbody fusion
a type of spinal
arthrodesis involving interbody grafting of the lumbar
spine using a posterior approach. Most frequently autologous
bone grafts from the ilium are used as tricortical or cortical cylindrical dowels. In some cases iliac or fibular strut grafts provide more stable immediate fixation; likewise metallic fixation devices have been used with success at the level of the disc space in some patients.
