title: A concise follow-up of a previous report: posterior reduction and anterior lumbar interbody fusion in symptomatic low-grade adult isthmic spondylolisthesis.
abstract: We report the updated results for a previously evaluated surgical treatment for adult low-grade isthmic spondylolisthesis. In 12 patients a decompressive laminectomy was performed followed by a circumferential fusion using posterior pedicle screw instrumented reduction and staged anterior cage-assisted interbody fusion. Average time to follow-up was 5.6 (range 4.9-6.6) years. The average Oswestry Disability Index at last follow-up was 14 compared to 13 at 2.1-year follow-up. The average VAS score for back pain at last follow-up was 2.3 compared to 2.8 at 2.1-year follow-up. Ten patients had resumed their pre-symptom work status. This study demonstrates maintenance of the good clinical and radiological 2.1-year outcome after 5.6-year follow-up with no deterioration of back-pain scores.
