The PLASTALLIUM™ system holds benefits for CEMENTED and CEMENTLESS fixation applications and is employed regularly in both approaches.
The surface topography of PLASTALLIUM™ 212 is ideal for mechanical interlocking of cement or bone. In the latter case, an additional coating layer of bio-conductive material (e.g. CAPTAL™ Hydroxyapatite) is employed to promote apposition of good quality bone to the implant.
