Abstract
Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.

A supra implant system for joining boney structures comprising:
- a first non-threaded anchor having a first center axis including,
- a first non-threaded elongated body;
- a first non-threaded head coupled to a proximal end of the elongated body, the first head including,
- a concentric portion of the first head that is substantially concentric to the center axis, and
- an offset portion of the first head that is offset from the center axis;
- a second non-threaded anchor having a second center axis including,
- a second non-threaded elongated body;
- a second non-threaded head coupled to a proximal end of the elongated body, the second head including,
- a concentric portion of the second head that is substantially concentric to the center axis, and
- an offset portion of the second head that is offset from the center axis;
- a supra implant including,
- a first end portion including a first aperture defined therein, the first aperture having a first rigid engagement feature, the first aperture sized and shaped to fully accept the first head only when the first rigid engagement feature engages the offset portion of the first head to force a first transverse movement of the first head;
- a second end portion including a second aperture defined therein, the second aperture having a second rigid engagement feature, the second aperture sized and shaped to fully accept the second head only when the second rigid engagement feature engages the offset portion of the second head to force a second transverse movement of the second, wherein the second transverse movement is in an opposite direction relative to the first transverse movement;
- and
- a main body portion joining the first end portion to the second end portion.
