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.
Claims7
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.
