Postoperative X-ray Follow-up of Lumbar Fusion with Semi-rigid Pedicle Screw

Abstract

Twenty cases underwent posterolateral fusion with the Diapason pedicle screw system for unstable spine. All patients were followed-up radiographically. One third of the patients showed loss of correction in %slip and slip angle. This reduced the lordosis in the lesion. We concluded that the reduction for unstable spine is difficult to be maintained with the Diapason system.
