Abstract:
A method of mounting a matrix to tissue, comprising the steps of:providing a graft fixation device, said device comprising:a first implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, and a longitudinal passage therethrough;a second implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, and a longitudinal passage therethrough;a proximal annular face on the proximal ends of the first and second implantation members surrounding the longitudinal passage; and,a connecting member connecting the first and second implantation members, the connecting member having a central section, a first end extending from the first implantation member and a second end extending from the second implantation member;forming a pair of spaced apart bore holes in bone;mounting the device to an insertion instrument having a pair of spaced apart prongs, said prongs having distal ends, such that the prongs are contained within the passages of the implant members and the distal ends extend beyond the distal ends of the implant members;placing a matrix onto the surface of the bone over the bore holes;and inserting the implantation members through the matrix and into the bore holes, thereby securing the matrix to the bone.
