The two-part Cempadic® silicone spacer moulds offer the surgeon the opportunity to prepare intraoperative cement spacers whose geometry corresponds to the EcoFit® hip stem. In a second step, the spacer is provided with a large head of bone cement, which has an articulating surface smooth enough to allow for a wear-reduced passive mobilization during the treatment. The Cempadic® spacer moulds are subsequently processed and resterilized as conventional instruments for re-use.
Cempadic® hip spacer moulds are in femoral sizes 6,25 to 17,5 and head diameters of 50 to 58mm available.
It is recommended to use bone cement with standard viscosity, such as implabond®, for making the cement spacers. The mixing of the bone cement and the application can be done by hand or by means of a mixing system and cement syringe.
In the case of infected revision interventions, all implant components are usually removed during the two-stage surgery, and the resulting joint spaces are filled with intraoperatively prepared pads or spacers made of bone cement. The spacers, which are loaded with antibiotics, are usually formed by hand and are generally not allowed to passively mobilize in the patient since the surfaces of the articulating spacers are incongruent and not smooth enough. After successful healing of the infections, these spacers are removed in a second surgery and replaced with new implant components.
