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.

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

Bone fusion system, plate system, guide, implant, kit and methods for using the bone fusion system, plate system, guide and implant are disclosed. The bone fusion system includes an alignment guide, an implant, and at least one fastener inserted through the implant. The alignment guide includes a body portion, a first lobe positioned at a first end of the body portion, a second lobe positioned at a second end of the body portion, and an extension member extending away from a first side of the body portion. The implant includes a body portion, a first arm extending away from the body portion in a first direction, a second arm extending away from the body portion in a second direction, and a third arm extending away from the body portion laterally between the first and second arms. Finally, methods for using the bone fusion system, plate system, guide and implant are disclosed.

A method of repairing plantar plate tears of an individual through augmentation that includes cutting an incision above a damaged area of a plantar plate on an individual, spreading the tissue with a plantar plate joint distractor, inserting a drill insertion member into the plantar drill guide and at a drilling angle over tissue at or near the damaged area of the plantar plate, drilling, with a drill bit and at the drilling angle, into the tissue at or near the damaged area of the plantar plate, attaching a K-wire to a graft, pulling, with the K-wire, the graft across a damaged area of the plantar plate augmenting the damaged area of the plantar plate, and manipulating an interference-type screw through the plantar plate and either or both the K-wire and the graft to engage and compress the graft for fixation.

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.

An osteotomy implant device includes a housing defining a cavity and having a central plane extending therethrough. The housing includes a first bone engaging surface and a second bone engaging surface. The second bone engaging surface disposed on an opposing side of the central plane from the first bone engaging surface. The osteotomy implant device also includes a cutting member. The cutting member rotatable coupled to the housing. The cutting member rotatable about an axis between a first position and a second position. The cutting member entirely disposed within the cavity between the first bone engaging surface and the second bone engaging surface in the first position. A portion of the cutting member extends beyond at least the first bone engaging surface or the second bone engaging surface of the housing in the second position.

A device for the repair of a phalangeal joint comprises a first anchor, a second anchor, and a flexible spacer connecting the first and second anchors. The flexible spacer comprises a plurality of elongate fibers extending axially or criss-crossed between the first and second anchors and a polymeric matrix interspersed with the plurality of elongate fibers. Specifically, a prosthetic metatarsophalangeal joint device comprises a porous metallic metatarsal bone anchor, a porous metallic phalangeal bone anchor, and a polymeric spacer element comprising parallel or criss-crossed elongate fibers that can connect the metatarsal bone anchor and the phalangeal bone anchor. Methods for manufacturing prosthetic joint devices comprise using three-dimensional printing processes or molding processes. Methods for implanting prosthetic joint devices comprise positioning porous metallic anchor components adjacent resected bones at planar interfaces and between which a polymeric spacer having axial aligned elongate fibers embedded in a matrix can be disposed.

An improved surgical system and procedure for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The correction factor can be based on a virtual model of the first and second bones in a deformed configuration and a corrected configuration. In the virtual corrected configuration, first and second virtual axes can be fixed in the respective first and second bones. When reverted to the virtual deformed configuration, the orientation of the first and second axes can be used to determine the correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration.

A device for use during an arthroplasty procedure of a joint of a patient, the joint extending between a first joint end of a first bone and an abutting second joint end of a second bone of the patient. The device includes first and second components that can be mated together. The first component includes an attachment fitting configured for disposing over the first joint end of the first bone and a stem extending from the attachment fitting and suitable for extending along an intra-medullary canal of the first bone. The second component includes an end plate configured to mate with the attachment fitting and a longitudinal plate extending from the end plate and configured for disposing along a medial, longitudinal surface of the first bone. The device also includes at least one fastener for coupling the longitudinal plate to the first bone.
