A tissue fixation implant that includes leading fixation and trailing fixation members, each fixation member having a proximal head and an elongate shank with a distal tip, and each fixation member adapted to at least partially contact the other fixation member at one or more points along their respective lengths. The tissue fixation implant includes a proximal inter-engagement feature for fixedly engaging each of the two fixation members relative to one another when engaged within tissue, including bone tissue, soft tissue, and combinations of these, and has an interior chamber suitable for receiving osteogenic material to enhance new bone growth and fusion of the fixation implant within bone. |
