An internal intramedullary fixation device for the stabilization of bone in arthrodesis and fractures of the foot and hand is disclosed. During implantation in medullary canals of bones, the device grasps the edges of the canals, stabilizing the bones, internally, during a healing process. The intramedullary fixation device comprises arrow-shaped proximal and distal heads comprising tips and a pairs of wings, the heads being sized to fit within an intramedullary canal of a bone. The intramedullary fixation device also comprises a rigid body defining a longitudinal axis connecting the proximal and distal heads. The rigid body comprises an intermediate portion, a distal neck portion connecting the rigid body to the distal head, and a proximal neck portion connecting the rigid body to the proximal head, the neck portions having a cross-sectional area smaller than a cross-section area of the intermediate portion.

A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a 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. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.

Assemblies and methods for fixation of bone or bone fragments using an orthopedic plate, a modular peg, and a compression screw. The modular peg is screwed into one of the apertures of the orthopedic plate. The modular peg may include an aperture having screw threads designed to receive the threads of the compression screw and serve as an anchor for the compression screw. By rotating the compression screw in relation to the modular peg, the compression screw may advance through the aperture of the modular peg, drawing the head of the screw toward the modular peg, and compressing the bone or bone fragments.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

The present invention is directed to a hinge joint implant (40) configured to fit in a joint cavity and which can comprise, when in situ, an at least hemi-spherocylindrical configuration, and further a hinge joint implant configured to fit in a joint cavity wherein the implant can extend around the sides of a joint component which may be a bone and/or cartilage. The invention further provides the use of a hinge joint implant according for treating arthritis, and/or torn cartilage, and a method for manufacturing a hinge joint implant from one or more pieces.

An orthopedic drill bit includes a cutting head formed to include diametrically opposed cutting lips leading to a central point and away to a radiused periphery to center said bit. The drill includes flutes extending from a cutting end, said flutes having a dulled periphery to prevent out of round holes. The flute design increases in width progressively from the tip up the shank, to maintain an adequate and unrestricted space for chips to easily move upward, preventing the chips from being compressed into a smaller opening while maintaining the tapered depth of the flutes for strength.

A solution is disclosed for deploying a fixation member into an aperture of a bone fastener. The solution may include a guide having a body that includes a proximal end and a distal end. The guide may also include a guide member coupled to the body near the proximal end. The guide member may be configured to guide placement of the fixation member to secure the bone fastener. The solution may include an engagement member coupled to the body near the distal end. The engagement member can be configured to engage the bone fastener such that the guide member is rotatable, relative to the bone fastener, about an engagement axis to the guide member at any of the plurality of relative orientations about the engagement axis.

An implant includes a curved first plate section having a curvature about a longitudinal axis extending in a longitudinal direction. The first plate section has a first hole and a second hole. The first hole and the second hole are positioned to receive respective bone screws for attaching the implant to a first curved surface of a bone having a syndesmosis. A second plate section extends continuously from the first plate section. The second plate section has at least a third hole that is positioned to be offset from the first hole and the second hole in a direction that is anterior or posterior from the first hole and the second hole in a case where the longitudinal axis is aligned along a superior-inferior direction. The third hole is configured to receive at least one screw or at least one button for holding a suture at a position offset from the first line segment hole and the second hole in the anterior or posterior direction, for reducing the syndesmosis.

In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.
