Patent ID: 7214232

Claim:
A method of mounting a matrix to a bone, the method comprising: providing a graft fixation device comprising: a first implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, a longitudinal passage therethrough, a proximal opening and a distal opening, wherein both openings are in communication with the passage; a second implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, a longitudinal passage therethrough, a proximal opening and a distal opening, wherein both openings are in communication with the passage; a retention member connecting the first and second implantation members, the retention member having a central section, a first end section extending from the first implantation member and a second end section extending from the second implantation member; and, an insertion member extending from the distal end of each implantation member, wherein the insertion member has a proximal end, a distal end, an outer surface, a proximal opening and a longitudinal passage in communication with the proximal opening, wherein said longitudinal passage has a distal blind end, and wherein the longitudinal passage of each insertion member is in communication with the longitudinal passage of the respective implantation members; and, at least one wing member extending from the retention member; accessing a bone; positioning a matrix member to the surface of the bone, said matrix member having a top surface and a bottom surface; mounting the graft fixation device to an instrument having a shaft having a distal end, a proximal end, and distal mounting pins extending from the distal end of the shaft, wherein the pins are engaged in the longitudinal passages of the implantation members and insertion members; and, manipulating the shaft such that the insertion members are caused to penetrate the matrix and the bone, thereby causing the implantation members to engage the bone, and the retention member to engage the matrix such that at least a section of matrix is maintained substantially in contact with the bone.
