An innovative dome toe resurfacing system for performing metatarsophalangeal joint replacement is disclosed. The present invention comprises a prosthetic implant for metatarsophalangeal joint, and one or more cone extensions that covers portions of the prosthesis that extends into the metatarsal bone and phalanx bone. The cone extensions include a plurality of ridges that will catch bone on insertion and provide a press fit. The present invention also includes a cone and cup reaming system wherein one or more reamers will ream a cone/cup shape for the articular surfaces, and prepare the metatarsal and phalangeal canals for the insertion of the cone extensions. The cone extensions have ends that fit the reamed cone/cup shape wherein the cone/cup shape resembles the natural anatomy of articular surfaces of metatarsophalangeal joint.

Disclosed are orthopedic implant kits. One disclosed kit comprises an implant having a joint head portion, the joint head portion having a generally convex distal surface and generally concave proximal surface, the implant comprising a post portion protruding proximally from the proximal surface, the post portion having a dorsal surface and a ventral surface (which is a plantar surface in the case of a metatarsal bone) and including a first threaded aperture extending therebetween, and a bone screw. The bone screw has a threaded shaft complementary to the threaded surface of the post portion and preferably is configured to provide bicortical fixation of the implant.

The present disclosure pertains to ionic polymer compositions, including semi- and fully interpenetrating polymer networks, methods of making such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging for such articles.

Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.

A bone fusion implant is provided for treating conditions of Proximal Interphalangeal (PIP), Distal interphalangeal (DIP), and metatarsophalangeal (MTP) foot joints. The bone fusion implant may be a cortical bone allograft sized to fuse the foot joint to be treated. A proximal portion of the implant may be pressed into a hole drilled in a proximal bone portion of the foot joint, and a distal portion of the implant may be pressed into a hole drilled in a distal bone portion of the foot joint. Ramps on the proximal and distal portions facilitate press-fitting the implant into the holes in the bone portions. Side ramps ensure that the bone fusion implant remains substantially aligned with the foot joint while the distal portion is pressed into the hole into the distal bone portion. Grooves on the ramps alleviate pressure and ease inserting the implant into the holes in the bone portions.

An improved joint implant apparatus, system, and method. The system includes an implant having a bone-facing articular surface configured to replace at least part of a natural articular surface of a bone adjacent to a joint. The system also includes a transosseous coupler and a bone anchor configured to reside proximate another surface of the bone, separated from the natural articular surface by a bone tunnel. The bone anchor is configured to couple the transosseous coupler to the bone such that the transosseous coupler retains the implant in place on the natural articular surface of the bone.

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.

An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

A flexible bone implant includes a proximal stem having a proximal end, a distal end, and a proximal conduit extending from the proximal end to the distal end of the proximal stem, whereby the proximal conduit is open at both the proximal and distal ends of the proximal stem. The implant includes a distal stem having a proximal end, a distal end, and a distal conduit extending from the proximal end to the distal end of the distal stem, whereby the distal conduit is open at both the proximal and distal ends of the distal stem. The implant includes a flexible hinge interconnecting the distal end of the proximal stem with the proximal end of the distal stem for allowing the proximal and distal stems to flex relative to one another. A proximal stem protective tube is disposed within the proximal conduit of the proximal stem and has a length that matches the length of the proximal conduit, and a distal stem protective tube is disposed within the distal conduit of the distal stem and has a length that matches the length of the distal conduit. The proximal stem, the distal stem and the flexible hinge comprise a unitary structure made of a polymer material.
