Wedge osteotomy device and method of use

An osteotomy implant system comprising:

• a tapered wedge shaped core constructed from a radiolucent material, the core having a central plane extending therethrough;
• a first bone-engaging surface extending at a first acute angle relative to the central plane on a first side of the core, the first bone-engaging surface having a first side facing portion having a first plurality of individual peaks formed therein;
• a second bone-engaging surface disposed on an opposing, second side of the core, the second bone-engaging surface having a second side facing portion having a second plurality of individual peaks formed therein, the second bone-engaging surface extending at a second acute angle relative to the central plane such that the first and second bone-engaging surfaces form a tapered shape;
• and
• a side surface extending along the core between the first bone-engaging surface and the second bone-engaging surface, the side surface comprising a lateral portion having an opening formed therein such that the opening is configured to engage an insertion tool, a medial portion disposed distal from the lateral portion, an anterior portion extending between the lateral portion and the medial portion, and a posterior portion disposed distal from the anterior portion,
• wherein each of the first and second side facing portions along the anterior and posterior portions includes an osteoconductive coating,
• wherein the side surface between the first and second bone-facing surfaces is free from the osteoconductive coating, and
• wherein the first and second pluralities of individual peaks are tapered such that each of the individual peaks slopes toward the lateral portion.

An implant for metatarsal/cuneiform arthrodesis, the implant comprising:

• a first bone-engaging surface having a first plurality of longitudinal grooves and a second plurality of transverse grooves extending therealong such that portions of the first bone-engaging surface extend between adjacent longitudinal grooves and transverse grooves to form a first set of individual peaks;
• a second bone-engaging surface having a first plurality of longitudinal grooves and a second plurality of transverse grooves extending therealong such that portions of the second bone-engaging surface extend between adjacent longitudinal grooves and transverse grooves to form a second set of individual peaks;
• and
• a side surface extending between the first bone-engaging surface and the second bone-engaging surface, the side surface comprising a lateral side wall having an aperture formed therein,
• wherein each of the first set of individual peaks and the second set of individual peaks includes an osteoconductive coating,
• wherein the side surface is free from the osteoconductive coating, and
• wherein the individual peaks in the first and second sets of individual peaks are tapered such that each of the individual peaks slopes toward the first side wall.
