Abstract:
A method for installing an implant in a bony structure of a subject's body, said structure requiring one of reinforcement and repair, comprising the steps of:a) forming a hole in said bony structure and removing debris-product of said forming from said hole; b) inserting an implant having a generally cylindrical wall into said hole, said implant being a hollow tube having a distal end, proximal end and having a length substantially coextensive with a depth of said hole, said implant having an external cross-section substantially similar to a cross-section of said hole, said implant further having a plurality of openings through said implant wall distributed along said wall length; c) filling said hollow implant tube with flowable cement under pressure, said tube wall openings permitting lateral flow of said cement from said hollow tube into said bony structure, said cement flowing from an injection tube having a discharge end inserted inside said implant with an internal interface between said hollow tube wall and said injection tube that is substantially tight against cement leakage from a distal end of said implant to maintain said pressure, said discharge end being movable along said implant length; d) bringing said cement in said implant and said cement in said bony structure to a non-flowable state.
