We investigated the clinical and radiological results of the surgical procedures selected for the pathology of degenerative spondylolisthesis. The procedures included fenestration, decompression with posterolateral fusion, and decompression with posterior lumbar interbody fusion in which the tricortical iliac bone or Titanium Fiber Mesh Block as the bone substitute was grafted. The procedures were selected based on segmental instability, sagittal alignment, disc height, and the activity of daily living. Eighty-six patients with a minimum 12 month follow-up period (average 45.1 months) were included in this study. The clinical score assessed using the Japanese Orthopaedic Association scoring system and the radiologic results were acceptable in all procedures selected based on the criteria. These results show our surgical strategy is reasonable and can be recommended for patients with degenerative spondylolisthesis.
