Implants, systems, instruments, methods, and kits for metatarsophalangeal joint arthroplasty may include metatarsal arthroplasty implants, repositioning guides, broach tools, inserter tools, and sterilizable packaging configured to facilitate metatarsal arthroplasty surgical procedures. The metatarsal arthroplasty implants may generally include an articular member having a convex articular surface, a concave bone-facing surface opposite the convex articular surface, and at least one side surface intermediate the convex articular surface and the concave bone-facing surface, as well as a central shaft sized for insertion into a metatarsal bone having a central shaft longitudinal axis, a central shaft proximal end coupled to the concave bone-facing surface of the articular member, and a central shaft distal end extending away from the concave bone-facing surface of the articular member along the central shaft longitudinal axis.

Joint implants, such as joint implants used for placement in toes to treat hammertoe are described. More particularly, joint implants that include a proximal portion configured to be inserted into a first bone, a distal portion configured to be inserted into a second adjacent bone, and an elongated body positioned between the distal and distal portion is described. The elongated body can define a length and include at least one metal rod extending from the proximal portion to the distal portion and a porous mesh extending along at least a portion of the elongated body length. The porous mesh can be configured to allow for bony in-growth upon implantation, wherein the elongated body defines a generally square cross section and is configured to be inserted into drilled circular holes in the first and second bones. Methods of fusing two adjacent phalanges of a two are also described.

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 relates to improved plate and screw systems for use in fusion and other surgical procedures, which improve the ability to effectively affix adjacent bodies without gapping or experiencing loss of compression over time. The systems include plates having armatures configured to receive bushings, the bushings configured to pivot and rotate and thereby permit a greater degree of orientation of corresponding screws placed through the bushings. In embodiments, the bushings comprise anti-rotation elements which lock the bushings in a desired orientation. Methods for use of the components described herein are also disclosed.

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.

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 first and second arms. Finally, methods for using the bone fusion system, plate system, guide and implant are disclosed.

Disclosed are devices and related surgical methods for replacing some or all of a metatarsophalangeal joint of a patient.

A graft-harvesting instrument and MTP fusion device are disclosed to allow for easy and safe removal of a section of the calcaneus to be used as autograft in the fusion of the MTP joint. The graft-harvesting instrument allows a surgeon to place a barrier between the saw and the vital anatomy on the medial side of the calcaneus. The MTP fusion device allows for the exact placement of the autograft into the MTP joint. The graft-harvesting instrument allows for a very consistent piece of autograft to be harvested. The graft-retaining sleeve component of the MTP fusion device positions that autograft in place for optimum fusion of the MTP joint.

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.
