Cement Delivery System for Interfacial Enhancement

The broad, long-term objective of this proposal is to commercialize optimized acrylic bone cement minjection components which will improve the long-term fixation of orthopedic implants and reduce cosproject will aim to design and fabricate prototype cement mixing and injecting components for appliccanal, validate their performance, and experimentally determine the resultant strengths of the cemeninterfaces. The components will be designed to reduce cost by minimizing the number of disposable pacompromising function. This work relates directly to the effectiveness and cost containment of joint350,000 procedures were performed in the U.S. in 1993. The hypothesis that will be experimentally tethe time from mixing onset to injection of the cement, increasing the injection shear rate, and ensuof the cement in the bone canal will improve the strength of the cement-bone and cement-prosthesis ihypothesis will be considered by comparing prototype designs to the existing current technology. Witdesign, manufacturing, and medical professionals, the tasks will be carried out in a concurrent engidevelopment environment.
