SYSTEMS AND METHODS FOR MONITORING THE CURE OF PMMA BONE CEMENT DURING SURGERY
The invention comprises a system which determines the cure status of bone cement which is then used in making surgical decisions on the cement use and further comprises a system for aiding in securing an implant to a bone using a cured grout or bone cement. The system includes a device which comprises a frequency sensor joined to a circuit to monitor one or more frequency signals, and to an indicator that emits a signal in response to a current emitted to the circuit by the system while monitoring the state of cure. The invention also relates to surgical methods using the system.

Polymeric adhesive for anchoring compliant materials to another surface
Methods, compositions, and kits for adhering polymers and other materials to another material, and in particular to bone or bone-like structures or surfaces. A composition of matter includes a urethane dimethacrylate-methyl methacrylate copolymer with a plurality of first polymer regions based on urethane dimethacrylate and a plurality of second polymer regions based on methyl methacrylate. The method includes placing an orthopedic joint implant having an attachment surface in a joint space, applying a first non-urethane-containing precursor, a second urethane-containing precursor, and a initiator to the attachment surface; contacting the first and second precursors and the initiator with the joint surface; and copolymerizing the first and second precursors and forming an adhesive copolymer and attaching the implant to the joint.
