A femur plate is provided, the femur plate comprising a first end portion anatomically pre-formed to conform to a trochanter region of the femur and a second end portion anatomically pre-formed to conform to a condyle region of the femur, wherein the second end portion comprises at least one first opening configured to receive a bone fastener. The femur plate further comprises an elongate shaft extending from the first end portion to the second end portion, the elongate shaft comprising at least one second opening configured to receive a bone fastener. Furthermore, a periprosthetic implant system comprising the femur plate and a method of implanting the femur plate are provided.

Femur plate

An insert for receipt within a plate aperture having an inner wall along the plate aperture includes a body and collar. The body has inner and outer surfaces. The inner surface defines an insert aperture having a longitudinal axis. The collar extends from the outer surface in a first radial direction perpendicular to the longitudinal axis and extends along only a portion of the outer surface in a second radial direction transverse to the first radial direction and the longitudinal axis. The collar defines a first radial distance from the longitudinal axis at a first position of the collar and a second radial distance from the longitudinal axis at a second position of the collar that differs from the first radial distance. A fixation system includes the plate and insert which is receivable within the plate aperture such that the collar contacts and is slideable along the inner wall.

Floating locking insert

A bone plate includes a bone-contacting surface, an upper surface opposite the bone-contacting surface, and a hole having a circumference and extending from the upper surface to the bone-contacting surface. The hole includes a first portion having a plurality of substantially parallel lips, each lip extends around the circumference of the hole and defines a diameter of the hole. The diameters of the hole, as defined by the lips, decrease in a direction from the upper surface to a center of the hole and increase in a direction from the center of the hole toward the bone-contacting surface.

Bone plates and associated screws

A system for treating tissue of a patient's anatomy at a target site. A localizer generates location data associated with the anatomy. A display unit overlays visual content on the anatomy within a field of view observable by a user. A visualization program on a computing device generates a virtual reference frame, identifies viable and non-viable approaches for fixation elements to engage tissue and secure a stabilizer relative to the target site based on patient-specific imaging data, arranges a virtual viability model within the virtual reference frame based on the location data and comprising viable portions associated with viable approaches and non-viable portions associated with non-viable approaches, and renders the virtual viability model in the visual content displayed by the display unit overlaid onto the anatomy within the field of view to assist the user in visualizing at least one of viable approaches and non-viable approaches.

Surgical systems and methods for facilitating tissue treatment

A device for positioning a bone plate includes a body having a first end having a first curved portion and a second end having a second curved portion. Each curved portion terminates at an abutment. Each abutment has a first diameter and the curved portions have a second diameter less than the first diameter. The first end secures the positioning device to a bone plate and the second end secures the positioning device to a soft tissue elevator.

Devices and methods for positioning of an implant

A bone plate for implanting in a femur bone having a prosthesis implanted therein includes a shaft portion defining a plurality of holes and a trochanteric portion proximal to the shaft portion having two arms forming a concave shape and defining a plurality of first holes for receiving screws such that when implanted, the two arms at least partially wrap around and attach to the femur bone. The bone plate may include at least one bendable extension positioned between both of the arms. Each of the extensions may define at least one second hole.

Trochanter plates

Various embodiments of a cable plug and a cable wire attachment plate are disclosed herein. Each plug or plate has a cable retaining portion and a fastening portion disposed from the cable retaining portion about a longitudinal axis of the plug or plate. Each cable retaining portion preferably has an aperture or channel for receiving a cable wire therein, while each fastening portion is adapted to engage a portion of a bone plate, such as a hole in the bone plate or an exterior surface of the bone plate. Related methods, systems, and kits are also disclosed.

Cable plugs for bone plates

A fixation system includes an elongate plate and an extension plate. The elongate plate includes an inner wall and has a longitudinal axis. The extension plate has first and second attachment portions offset from one another. An engagement portion extends outwardly from the first attachment portion. The engagement portion is couplable to the inner wall of the elongate plate. The second attachment portion defines an aperture for receiving a fastener. The second attachment portion is revolvable about the longitudinal axis of the inner wall when the engagement portion is coupled to and movable about the inner wall. A fastener is received into the first attachment portion to attach the extension plate to the elongate plate. Another fastener is received into the second attachment portion and into a bone part.

Periprosthetic extension plate

A bone plate has a first and a second surface opposite to the first surface, and a deformable contact surface region. The plate has a through hole defining a through hole axis and an inner surface of the bone plate and extending from the first surface through the bone plate to the second surface. The contact surface may be formed by at least part of the inner surface, wherein the deformable contact region comprises a plurality of cavities at least partially surrounding the through hole and each extending in a height direction of the bone plate. Alternately, the deformable contact region may comprise at least one cavity surrounding the through hole in a circumferential direction of the through hole. Also provided is a bone plate system comprising the bone plate and a fastening member being configured to cooperate with the deformable contact region of the bone plate.
