Bone implant with means for multi directional force and means of insertion

A tissue fixation system comprising:

• an implant, wherein the implant is movable between a first configuration and a second configuration;
• and
• an inserter having first and second arms connectable to the implant, the inserter including:
• a body having a proximal end and a distal end, and a length from the proximal end to the distal end, the body defining a width along a first direction, and the body including first and second outermost surfaces that extend from the proximal end to the distal end along the length, wherein the first and second outermost surfaces are opposite each other along a second direction so as to define a thickness of the body, the second direction is perpendicular to the first direction, and the width is less than the length and greater than the thickness;
• a rod that is elongate along a central axis that is perpendicular to each of the first direction and the second direction, wherein the rod is threadedly mated with the body, and the first and second arms are spaced from each other along the first direction,
• open void space that extends entirely through the body from the first outermost surface to the second outermost surface along the second direction, wherein the void space defines a total length along the central axis that is greater than half the length of the body;
• a knob that is rotatably coupled to the rod such that rotation of the knob relative to the body in a direction of rotation about the central axis causes the implant to move to the first configuration when the inserter is connected to the implant,
• wherein the implant is configured to be fully seatable in a final position against a tissue when the implant is in the first configuration;
• wherein the inserter is configured to disconnect from the implant when the implant is fully seated in the final position, such that the implant moves from the first configuration to the second configuration, whereby the implant is configured to apply a compressive force to the tissue when the implant is in the second configuration.
