Isthmic Spondylolisthesis Treated With Combined Approach: Clinical and Radiological Outcomes

Isthmic Spondylolisthesis Treated With Circumferential Arthrodesis Combining Anterior Lumbar Interbody Fusion With Posterolateral Fusion. About 150 Cases

This study aims to evaluate clinical and radiological outcomes of isthmic spondylolisthesis surgically treated with combined approach. The goal is to demonstrate that it is a safe and efficient technique to treat isthmic spondylolisthesis. There is very little literature concerning this procedure.

The goal is to demonstrate that it is a safe and efficient technique to treat isthmic spondylolisthesis using standard XRays, CT Scan and patient reported outcome measurements. There is very little literature concerning this procedure.
