[Technic of lumbosacral graft in the surgical treatment of dysplastic spondylolisthesis].

The authors describe a method of treatment for spondylolisthesis using a posterior approach, reduction and fixation with Harrington rods and cortical fibular graft driven through the sacrum, across the lumbosacral intervertebral disc into the body of the 5th lumbar vertebra. The technique is completed by a postero-lateral graft. This technique avoids the need for an anterior approach.
