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.

Modular orthopaedic component case

A case for modular neck components for hip implants. The case may include indicators based on independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The case allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables. A method described herein may include preoperative planning in which a template including a grid coordinate system is used, which advantageously provides an intuitive system for the surgeon both preoperatively and during surgery.

The needle portion has a spacer portion along the handle axis, and has a distal end. The needle portion includes a substantially helical portion that is a variable spiral portion, extending from the straight spacer portion. The variable spiral portion is sized and shaped to extend from an incision substantially adjacent the patient's obturator foramen through the obturator foramen along a path in a region between the superior pubic ramus and the inferior pubic ramus. The needle portion has a structure near the distal end that associates the instrument with an implantable material configured to treat incontinence.

Foot prosthesis with resilient multi-axial ankle

The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element. The gap may be filled with a resilient material.

Complete hip prosthesis femoral component has insert that allows head to be set in different positions relative to shank

The femoral component, comprising a shank (1) and a hemispherical head (40), has an insert (50) that fits on the neck (21) of the shank and receives the head. The insert's inner and outer surfaces have different axes of rotation (53, 55) that coincide with those (31, 42) of the neck and head and are offset relative to one another at an angle of about 5 degrees. By rotating the insert relative to the neck the head of the prosthesis can be set in different positions relative to the shank.
