Abstract
Cement augmentation of iliosacral screws is a novel technique to treat sacral insufficiency fractures in a geriatric population. Non- or minimally displaced sacral fractures are suitable for this technique. Prior to screw insertion, CT-evaluation is required in order to find and plan the correct corridor for the screws. Consecutively, special cannulated screws with side perforations near to the screw tip are implanted. If the surgeon has the impression of poor screw anchorage in the osteoporotic sacrum, 2–3 mL PMMA-based bone cement is injected through the screw. This leads to improved screw anchorage, may allow full weight bearing and reduces secondary screw loosening. Own data from an in vitro biomechanical study suggests that cement augmentation significantly increases the number of cycles to failure at the screw tip, but does not affect the overall construct stability. Significant pain relief and early patient mobilization have been perceived in our patients. Multi-center based clinical experience is lacking so far. Further clinical and biomechanical work is needed to confirm our preliminary data.
