  • Publication number: 20240076438
    Abstract: 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.
