Application of bone cement ultrasonic extractor in removing the broken polymer stems

This article presents the first experience of using ultrasound extractor of bone cement in removing of broken plastic endoprosthetic stem after 14 months of implanting. This method allowed by saving potential bone for possible future re-replacement, to achieve a similar quality to the primary tumor endoprosthesis stem fixation. solving the problem of any kind of replacement complications is the search and development of unique, non-standard, but at the same time rational and easy implementation techniques. The present study shows the possibility of ultrasound extractor to remove not only the bone cement in difficult extractable stems, but if necessary any plastic endoprosthesis elements.
