Abstract
Introduction
The spondylolisthesis lytic is a very unstable pathology and a reduction with a 360-degree stabilization improve solid fusion, only a posterior approach is not enough, is possible to see a broken transpedicular screw.
Patient and Methods: We present a case of a 36-year-old woman with a spondylolisthesis lytic grade 2 who underwent just a posterior screw fixation; 6 months after surgery she feels lumbar and radicular pain, the rx shows a left S1 broke screw.
Results
We present a minimally invasive anterior lumbar interbody fusion plus a revision by posterior way to achieve reduction and circumferential fixation with percutaneous transpedicular screws preserving the muscular and ligamentous posterior tension band. The surgical time was 70 minutes, the blood loos 50 mL, time to discharge 23 hours after surgery and the return to normal activities in 5 days. The VAS pre-op was 8 and post-op 2, oswestry disability index post-op was 4.
Conclusion
The spondylolisthesis lytic needs a 360-degree approach to produce safe stabilization and possibility of solid fusion and a minimally invasive techniques allow to preserve muscular and ligament injuries and help the patient to return to normal activities shortly.
