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.
Claims8
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 first 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;
- an implant including,
- a first 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, and
- a first force applying feature sized and shaped to assert a transverse force on the second portion of the first head as the second portion of the first head slidingly engages the first force applying feature;
- wherein the first distal portion is sized and to allow passage of the first elongated body along a first trajectory,
- wherein the first proximal portion is 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 wherein the transverse movement is only caused by the interaction of the second portion of the first head with the first force applying feature.
