Description
Sunil Khemka and co-authors asked whether restoring the lower spine's natural curve improves results after fusion surgery for a slipped vertebra. Isthmic spondylolisthesis, where one vertebra slides over the next, causes back pain and disability. Fifty patients received a posterior lumbar interbody fusion and were followed for a year with disability scores and spinal alignment measures.
Disability scores improved sharply after surgery. Of the alignment measures, only the sacral slope, the tilt of the sacrum's top surface, changed significantly, rising as pelvic tilt fell. Greater gains in sacral slope went with greater disability improvement. The authors conclude the surgery clearly helps, and that recovering sagittal balance, above all sacral slope, supports the best function, though alignment alone does not predict every outcome.
