Joint or segmental bone implant for deformity correction

An implant for use in an ankle joint among reconditioned surfaces established on a distal end of a tibia bone, a talus bone, and a calcaneous bone, the implant comprising:

• a component having at least three convex outer surfaces adapted to be disposed against the reconditioned bone surfaces such that the component interfaces in a complementary manner with the reconditioned distal end surface of the tibia, the reconditioned surface of the talus and the reconditioned surface of the calcaneous, the component defining a cylindrical opening therethrough, the opening defined by a plurality of struts, a combination of some of the struts extending from a first end of the opening to a second end of the opening and defining a straight line;
• and
• an intramedullary nail configured to pass through the opening in the component when the nail is driven through the calcaneous and into the tibia,
• wherein each of the bone surfaces is reconditioned to have a concave surface, and
• wherein the component is configured to be placed in a bone bed at least partially formed from the reconditioned bone surfaces such that at least one convex surface of the component is in contact with each of the concave distal end surface of the tibia and the concave surface of the talus and the concave surface of the calcaneous for selectively positioning the ankle joint relative to the component and aligning the nail with the distal end surface of the tibia.

An implant for use with reconditioned surfaces of a first bone, a second bone, and a third bone, the implant comprising:

• a spherical component adapted to be disposed in contact and in a complementary manner with the reconditioned first bone surface, the reconditioned second bone surface, and the reconditioned third bone surface, the component including a web structure defining an opening therethrough and an exterior separated from the opening by the web structure;
• and
• an intramedullary nail configured to pass through the opening in the component when the nail is driven through the first bone and into the second bone,
• wherein each of the bone surfaces is reconditioned to have a concave surface, and
• wherein the component is configured to be placed in a bone bed at least partially formed from the reconditioned bone surfaces such that the component is in contact with the concave surface of the first bone, the concave surface of the second bone, and the concave surface of the third bone for selectively positioning the bones relative to the component and aligning the nail with the second bone.

An implant for use with reconditioned surfaces of a first bone, a second bone, and a third bone, the implant comprising:

• a component having at least three convex outer surfaces adapted to be disposed in a complementary manner against one of the reconditioned bone surfaces, the component including an internal web structure and defining a channel extending therethrough, the channel and the outer surfaces of the component being provided by polygonal lattices and the internal web structure extending between the outer surfaces and the channel;
• and
• an intramedullary nail configured to pass through the channel in the component when the nail is driven through the first bone and into the second bone,
• wherein each of the bone surfaces is reconditioned to have a concave surface, and
• wherein the component is configured to be placed in a bone bed at least partially formed from the reconditioned bone surfaces such that the at least one concave surface of the component is in contact with the concave surface of the first bone, the concave surface of the second bone, and the concave surface of the third bone for selectively positioning the bones relative to the component and aligning the nail with the second bone.
