An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complementary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.

A total hip femoral prosthesis provides a shortened neck and more proximal coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes instrumentation for cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.

The invention relates to a prosthesis for implantation into a long bone during joint arthroplasty, particularly Total Shoulder Arthoplasty and Total Hip Arthroplasty, and a method for use of the implant.

A system for assisting in a surgical process, comprising: (a) a surgical device taken from a group consisting of a surgical tool and a surgical implant; (b) a positional sensor carried by the surgical device, the positional sensor including a wireless transmitter and associated circuitry for transmitting sensor data from the transmitter; and (c) a computer system including a wireless receiver and signal conditioning circuitry and hardware for converting sensor data received by the wireless receiver into at least one of (i) audio feedback of positional information for the surgical device and (ii) visual feedback of positional information for the surgical device.

A device is used to treat periprosthetic fractures, such as a fracture below the stem of a total hip replacement (THR). The device includes a clamp that is fixed to the exposed stem of the THR and a coupling, such as a morse taper, extending distally away from the stem. A post is inserted into the canal of the distal femur below the fracture. The post has a coupling extending proximally away from the distal femur. The couplings on the clamp and post are joined to create a stable connection between the patient's hip and distal femur. Instead of connecting the clamp with the post directly, one or more adapters may be provided to adjust the length and angulation of the treated limb. The device may also connect a THR stem with a Total Knee Arthroplasty (TKA) that includes a stem.

The invention relates to an endoprosthesis shaft system for elongate bones, comprising an anchoring part and a shaft, which is formed from module elements that can be coupled by means of a plug-in connection, wherein a mutual rotation of the elements along the shaft is adjustable and is blocked by means of an anti-rotation mechanism. In order to adjust the rotation, a rotation piece is provided as a further module element, which has a self-contained rotation adjustment device and a clamping device as a mechanism for blocking the rotation. The rotation piece comprises two end faces for the plug-in connection and a sleeve. The invention provides, with the rotation piece, a particular module element for the shaft, which as a structural unit allows both an adjustment of the rotation and a blocking against undesired rotation in a self-contained unit.

The proximally fitting femoral component with adjunctive fixation screws replaces a natural femoral head and proximal femur of a patient during a partial or total hip replacement. The femoral component includes an intramedullary stem having a proximal portion and a distal portion, a neck extending from the proximal portion, and a ball removably attached to a tip end of the neck, the ball forming a ball and socket joint with the acetabular cup of a hip prosthesis. Fixation screws may be installed in the proximal portion of the stem for added rotational and axial stability when necessary. An alignment device is removably attachable to the femoral component for aligning screw holes in cortical bone of the femur with holes or bores in the proximal portion of the stem. The fixation screws may extend in an anterior posterior or medial-lateral plane.

Modular endoprosthesis for at least partial replacement of a tubular bone, including, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece including a support body with a neck part arranged on the medial aspect thereof. The module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention.
