Pedicle screw augmentation in osteoporotic spine: indications, limitations and technical aspects.
European Journal of Trauma and Emergency Surgery : Official Publication of the European Trauma Society 2017 Februrary
PURPOSE: The need for spinal instrumented fusion in osteoporotic patients is rising. In this review, we try to give an overview of the current spectrum of pedicle screw augmentation techniques, safety aspects and indications.
METHODS: Review of literature and discussion of indications, limitations and technical aspects.
RESULTS: Various studies have shown higher failure rates in osteoporotic patients, most probably due to reduced bone quality and a poor bone-screw interface. Augmentation of pedicle screws with bone cement, such as polymethylmethacrylate or calcium based cements, is one valid option to enhance fixation if required.
CONCLUSIONS: Crucial factors for success in the use of augmented screws are careful patient selection, a proper technique and choice of the ideal cement augmentation option.
