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.

Alignment instruments may include joint-line referencing systems having an alignment arm having a body with first and second portions defining first and second sides. The first portion has at least one first pin tube through-hole extending from the first to the second side. The second portion has a first opening on the first side. A pin tube guide member is receivable in the first through-hole. The pin tube guide member has a passageway therethrough. An angelwing alignment member includes a portion receivable in the first opening of the alignment arm. An alignment foot is secured to the second portion, and the alignment foot has a handle and a shim. The shim is positionable in a joint between a first bone and a second bone, the alignment arm is alignable relative to a first bone, and the pin tube guide is operable for securing a pin into the first bone.

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.

A bone joint implant (1) has a proximal part (120) for translational motion over the trapezium in a first carpometacarpal joint and a distal part (110) for intramedullary engagement in the first metacarpal bone. An articulating coupling (103, 121, 123) is for multi-axial motion with translational movement over a bone in one part (120) and rotation in the other part (110) about the articulating coupling (121, 103). A flange (105) extends radially and around the coupling to limit relative rotational motion of the proximal and distal parts about the coupling, and to provide resilience for contact between the proximal and distal parts. The flange has a contoured surface (101) matching an abutting surface (125) of the proximal part (122) upon articulation of the parts in use to extreme positions. The flange (105) is included in an insert (100) in a stem (111) of the distal part (110), the flange extending proximally of the stem (111) and prohibiting contact between the proximal part (120) and the stem (111) during articulation.

A surgical guide includes a body having a shape that corresponds to a shape of an implant to be implanted. The body defines a first opening and at least one hole that is sized and configured to receive a tool. A first alignment feature configured to facilitate alignment of the surgical guide with a first anatomic plane is coupled to the body. Systems and methods also are disclosed.

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.

A joint prosthesis system is suitable for cementless fixation. The system includes a metal implant component that has a mounting surface for supporting an insert. The metal implant component includes a solid metal portion and a porous metal portion. The porous metal portion has surfaces with different characteristics, such as roughness, to improve bone fixation, ease removal of the implant component in a revision surgery, reduce soft tissue irritation, improve the strength of a sintered bond between the solid and porous metal portions, or reduce or eliminate the possibility of blood traveling through the porous metal portion into the joint space. A method of making the joint prosthesis is also disclosed. The invention may also be applied to discrete porous metal implant components, such as augment.

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.

The present disclosure provides for a wrist arthroplasty system and method that enable an expedient surgical procedure, maintain wrist motion, and reduce the likelihood of implant loosening. The system includes a capitate implant, a radial implant, and a resection instrument. The capitate implant includes a convex head formed to interface with a concave socket of the radial implant. The capitate implant includes a single stem formed to be secured within a patient's capitate bone. The radial implant includes lips formed to increase wrist joint motion and to help prevent dislocation of the capitate implant from the radial implant. The resection instrument may be used in combination as a measurement tool for determining the proper implant size, a guide for properly positioning the implants, and a trial tool for testing trial implant components before securing the final radial and capitate implants.
