There is disclosed a bone fixation device that can include a cage having an optional mesh portion. The bone fixation device can be configured to couple a leg portion to a foot portion of a user's body. In at least one embodiment, the device includes at least one cage having a plurality of struts forming cells. There can be an optional mesh portion having a pre-set porosity that can be either constant or variable in density. In at least one embodiment there can be a cage portion which is substantially spherical shaped. Alternatively, the device can be substantially egg shaped. In at least one embodiment there can be a central post hole for receiving a post. In another embodiment at least one plate or shaft can connect to the cage.

Bone fixation device

A process for printing a talus implant comprising the steps of scanning a joint for a damaged talus, and scanning a contralateral joint for a healthy talus. Next, the process includes obtaining dimensions for a talus based upon an initial scan and then obtaining dimensions for a talus based upon the scan of the contralateral joint. Next the process includes inverting the dimensions of the talus in the contralateral joint and then comparing the dimensions of the calculated talus with a pre-set of dimensions in a database. Next the process includes exporting a set of dimensions to a printer to print a talus implant.

Talus formation and implantation method

There is a process for correcting a bone injury, an implant for correcting the bone injury and a kit for applying the implant for correcting the bone injury. The process can be made substantially uniform with the application of a standardized kit. In at least one application the process is for correcting a bunion on a patient. The process can include applying a first drill guide to a bone, and then a second drill guide. Once the drill guides have been applied and wires have been inserted into a bone, an implant can then be applied to correct a bone injury and to allow the bone injury to heal.

Process, kit, and implant for correction of a bone injury

There is an implant, comprising a plate portion at a first end, and a stem portion at a second end extending away from an end of the plate portion. In one embodiment, the plate portion comprises a first lobe with a first screw hole; and a second lobe with a second screw hole, wherein the first lobe is adjacent to the second lobe. There is also method of inserting an implant, comprising preparing a patient's bones, performing an osteotomy on the patient's bones to form a first bone segment and a second bone segment, aligning the first bone segment and the second bone segment and inserting an implant into an intramedullary canal in the second bone segment.

Bone fixation device and method of use

There is a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, comprising a bone plate portion including an outer surface, an inner surface and at least one fixation aperture extending from the outer surface to the inner surface and a bone wedge portion extending from the plate portion at a first end and a free opposite end, the bone wedge portion comprising a porous architecture configured to promote bone ingrowth, the wedge portion defining first and second engagement surfaces for engaging the first bone segment and a second bone segment, respectively. There is also a method of manufacturing a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, a method of promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, and a fixation kit.

Bone fixation devices

At least one embodiment comprises a talus implant comprising: a body section; a neck section; a crown, wherein the crown is positioned at a top portion of the body section; at least one wing coupled to the body section, wherein the wing extends out from the body section. At least one embodiment further comprises at least one screw hole positioned in at least one of the neck section and the body section. In at least one embodiment the outer surface of the implant is polished. In at least one embodiment a portion of the outer surface is polished while a portion of the outer surface is roughened.

Talus implant

An implant including a first segment at a first end, a second segment at a second end, and an intermediate segment coupled to the first segment on a first end and coupled to the second segment on a second end. The first segment may include an insertion tip at the first end of the implant and a body portion adjacent to the insertion tip, the insertion tip extending out from the body portion. The second segment may include an end member at the second end of the implant and a body portion adjacent to the end member, the end member extending out from the body portion. The second segment may include a plurality of tip portions spaced about a longitudinal axis of the second segment, and the tip portions each including at least one barb formed by a taper portion and an engagement portion extending radially into the tip portion.
