cemSys® PMMA Bone Cement Product information cemSys® The first total hip replacement using a PMMA cement took place in the 1950’s. Since then cemented implants have become a gold standard in total hip and knee arthroplasty. Today surgeons can choose between a variety of cements with different viscocities, available with and without added antibiotics. cemSys® fulfils all requirements of a proven high quality bone cement • More than 10 years of clinical history • Mechanical properties superior to the International ISO 5833 standards • Two different viscosities for various applications • Short waiting time and an efficient application time • Stable packaging, liquid in an ampule and powder in a bottle 2 Mathys Ltd Bettlach • Robert Mathys Strasse 5 • P.

This could potentially lead to tissue necrosis, which is why the ISO 5833 (2002) stand- ard places a limit of 90°8 C on the hardening tempera- 70 ture of bone cements. The peak reaction temperature of cemSys is well within this limit. 6 67°C 79°C 50 4 30 2 1 0 0 cemSys® cemSys® genta 1 genta 3 cemSys® 1 Different viscosities to match surgeon’s preference high viscosity Viscosity is an essential handling property for surgeons. Viscosity To match the needs and preferences of different sur- geons, we supply both a high and low viscosity bone cements. cemSys 3 is our low viscosity bone cement, which is initially more liquid, while cemSys 1 is our high viscosity cement, which is initially slightly thicker. Time The products are available with and without antibiot- ics. All cements comply with the International ISO 5833 standard for PMMA bone cements which define the cemSys® 3 physical, mechanical, packaging and labelling require- ments. low viscosity Viscosity Time 4 Mathys Ltd Bettlach • Robert Mathys Strasse 5 • P.

Gentamicin is an antibiotic which cov- product, we limit the amount of antibiotics to about ers approximately 75 % of all bacteria-based pathogens. 3 – 4 % of the total powder volume. Its addition to bone cements prevents the adherence of bacteria to the cement surface and surrounding tissue, reducing the risk of bacterial growth and infection. cemSys genta starts with a high initial release of anti- biotics, which steadily decreases over time.
