Is there an increased risk of embolism using the REX Cement Stop?
No. Studies in fresh frozen bone by Prof. C. Heisel at the University of West-Virginia, Morgantown, has shown that inserting cement restrictors (especially oversized restrictors) leads to more extrusion of debris into the circulation. The REX Cement Stop will be inserted in its initial (small) shape and will expand locally. This means that there is no pressure on the intramedullary canal during insertion. This results in a risk of embolism that is lower than with commonly used cement restrictors.
