Spinal implants and instruments

An intervertebral spacer inserter includes a sleeve having a longitudinal axis, a hollow sleeve bore extending through the sleeve along the longitudinal axis, a sleeve tip end and an opening of a passage disposed in the sleeve tip end. The passage extends into the sleeve to the sleeve shaft along a passage axis that intersects the longitudinal axis at an angle less than about 90°. A sliding tip with an elongated slot is in contact with the sleeve tip end and is moveable with respect to the sleeve tip end between a first position with the opening accessible through the elongated slot and disposed adjacent a first end of the elongated slot and a second position with the opening accessible through the elongated slot and disposed adjacent a second end of the elongated slot opposite the first end.

Ankle prosthesis and methods of using the same

The present disclosure pertains to ankle prostheses. In an example embodiment, the ankle prosthesis comprises an adjustable and replaceable intermediate implant that is disposed between a tibial implant and a talar implant. The intermediate implant is adjustable relative to the tibial implant and can be interlocked therewith once adjusted. Methods of using, fitting, and adjusting the device are also described. Still other embodiments are described.

SIDE-SPECIFIC ORTHOPAEDIC SURGICAL INSTRUMENT SYSTEMS AND ASSOCIATED METHODS OF USE

A surgical instrument system includes a pair of side-specific orthopaedic surgical instrument assemblies. The right-limb side-specific instrument assembly is kitted so as to be devoid of left-limb side-specific instruments and vice versa.

Method and apparatus for manufacturing an implant

An orthopedic device includes a femoral implant having a non-custom internal bone engagement surface. The femoral implant includes at least nine parameters adjusted preoperatively to correspond to a specific patient. The parameters can include patient-specific lengths, such as, for example, medial and lateral condyle widths and notch height, and patient-specific medial and lateral angles.

Femoral augments for use with knee joint prosthesis

A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

UNICONDYLAR TIBIA IMPLANTS

Unicondylar tibia implant devices having a bone-facing, distal side that can be detailed with cement fixation features and may include any of or a plurality of grooves, pegs, fins, rails, cavities, and/or coating whereby the geometry of the implant device improves implant-to-cement or cement-to-bone fixation characteristics exceeding that of a traditional flat surface. The implant device may also include a proximal side facing away from the bone-facing, distal side and having a geometry that provides either articulation with (cartilage and meniscal substituting) or receipt of a secondary device coupleable to the implant device on the distal side of the secondary device that features an away-from-bone facing articulating feature. Additionally, the geometry of the implant device in anterior-posterior and medial-lateral directions, among other directions, provides a variety of improvements relative to currently available devices.

Anatomically Shaped Knee Joint Augment

The present disclosure relates to a knee joint augment having an anatomical shape. More specifically, the present disclosure relates to a knee joint augment that is used for artificial joint replacement to replace lost bone, wherein the augment is used in artificial knee replacement surgery to be coupled to a knee implant. The augment includes a top surface configured to be brought into contact with a distal surface of a base plate that forms the body of a tibia element and a bottom surface configured to be brought into contact with a cut surface of a tibia. The bottom surface has an area smaller than that of the top surface, and has a tapered shape that narrows from the top to the bottom. An intermediate line at which one end surface cut to be perpendicular to the top surface and an outer surface meet each other has a shape that is outwardly convex to the outside of the augment with respect to a straight line connecting a top point where the intermediate line and the top surface meet and a bottom point where the intermediate line meets the bottom surface, whereby the intermediate line has a shape corresponding to the anatomical shape of a cut bone.
