Knee prosthesis is a well\u2010recognized limb salvage procedure for osteosarcoma of the distal end of the femur. One drawback is that prostheses have a limited life and prosthetic failure with the inherent high rate of reoperations remains a serious long\u2010term problem for former osteosarcoma patients. The segmental cement extraction system (SEG\u2010CES) is a technique to remove cement in arthroplasty revision, based on a cement\u2013bone interface with a lower strength compared to the old cement\u2013new cement interface. We report the case of a 32\u2010year\u2010old former osteosarcoma patient in whom the SEG\u2010CES was applied to remove a long\u2010stemmed total knee cemented prosthesis. The prosthesis was placed 17 years before for a recurrent telangiectatic osteosarcoma of the left femur. Thirteen years after the prosthesis implantation, the patient complained of knee instability, pain, and complete failure of the extensor apparatus. The extraction of the prosthesis was performed using cylindrical batters of diameter corresponding to the diameter of the axle, two hammer extractors clamping the prosthesis components between two jaws. Extraction of the periprosthetic cement in the femoral and tibial components was done using the SEG\u2010CES technique. The successful prosthesis removal performed in this patient allowed us to perform an external fixation with bone lengthening and reconstruction by the Ilizarov method.<\/jats:p>","DOI":"10.1007\/s00167-004-0575-8","type":"journal-article","created":{"date-parts":[[2005,1,19]],"date-time":"2005-01-19T11:59:44Z","timestamp":1106135984000},"page":"557-563","source":"Crossref","is-referenced-by-count":13,"title":["Segmental cement extraction system (SEG\u2010CES) and the Ilizarov method in limb salvage procedure after total knee cemented prosthesis removal in a former osteosarcoma patient"],"prefix":"10.1002","volume":"13","author":[{"given":"Giulia","family":"Ottaviani","sequence":"first","affiliation":[{"name":"Institute of Pathology University of Milan Via della Commenda, 19 20122 Milan Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Randelli","sequence":"additional","affiliation":[{"name":"U.O.
