System and method for joining boney structures

A method for joining a first boney structure to a second boney structure, the method comprising:

• positioning an implant between the first boney structure and to the second boney structure;
• introducing a first non-threaded anchor into a first non-threaded aperture defined in the implant, the first anchor including a first non-threaded proximal head and a first non-threaded elongated body;
• introducing a second anchor into the second aperture defined in the implant, the second anchor including a second proximal head and a second elongated body,
• applying a non-torsional force onto a proximal end of the first head to drive the first elongated body, through the first aperture, and into the first boney structure along a first trajectory;
• applying a non-torsional force onto a proximal end of the second head to drive the second elongated body through the second aperture, and into the second boney structure along a second trajectory;
• continuing to apply the non-torsional force onto the proximal end of the first head as the first head reaches the first aperture and causing the first head to interact with the first aperture such that the first head moves transversely with respect to the first trajectory which causes the first boney structure to also move transversely with respect to the first trajectory;
• and
• continuing to apply the non-torsional force onto the proximal end of the second head as the second head reaches the second aperture and causing the second head to interact with the second aperture such that the second head moves transversely with respect to the second trajectory which causes the second boney structure to also move transversely with respect to the second trajectory.

An implant system for joining boney structures comprising:

• a first non-threaded anchor including,
• a first non-threaded elongated body having a center axis,
• a first non-threaded head coupled to a distal end of the elongated body, the first head including a first portion of the first head that is substantially concentric to the center axis and a second portion of the first head that is offset from the center axis;
• a second non-threaded anchor including,
• a second non-threaded elongated body having a center axis,
• a second non-threaded head coupled to a distal end of the elongated body, the second head including a second portion of the second head that is substantially concentric to the center axis and a second portion of the second head that is offset from the center axis;
• an implant including,
• a first bone engaging surface and a second bone engaging surface;
• a first aperture defined within the implant, the first aperture having a first proximal portion and a first distal portion exiting through the first bone engaging surface,
• the first distal portion sized and to allow passage of the first elongated body along a first trajectory,
• the first proximal portion sized and shaped to accept the first head only upon an occurrence of transverse movement of the first head with respect to the first trajectory;
• a second aperture defined within the implant, the second aperture having a second proximal portion and a second distal portion exiting through the second bone engaging surface,
• the second distal portion sized and to allow passage of the second elongated body along a second trajectory, and
• the second proximal portion sized and shaped to accept the second head only upon an occurrence of transverse movement of the second head with respect to the second trajectory.
