A modular variable blade augment including an augment component and a blade component. The blade component includes a buttress portion and a neck portion, with the neck portion having a body segment and a face segment that is contoured for mating engagement with an outer surface of the acetabular shell. The augment component has a first opening sized and shaped to receive insertion of the body segment, and which is also sized to accommodate selective adjustment of linear and angular orientations of the blade component relative to the augment component when the body segment is positioned in the first opening. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the modular variable blade augment is in an assembled configuration. Further, cement can be injected into the internal cavity to unitize the connection between the acetabular shell and the blade component.

Modular variable angle blade augment

Systems, devices and methods for guiding placement, orientation, and fixation of an orthopedic implant. Examples include a surgical guide having a first surface structured to fit within a prosthetic cup, at least one guide hole through the first surface, and an alignment structure having a contour formed from data indicative of the patient anatomy. The contour of the alignment surface is complementary to a portion of the patient anatomy in a unique orientation that aligns the guide hole with tissue suitable for receiving a fastener. The alignment structure preferably includes an arm with a first end coupled to a rim of the guide and a second end coupled to the contour. In certain implementations, the guide includes a plurality of alignment structures. Further disclosed are methods of making and using a surgical guide for aligning an orthopedic implant.

Variable angle blade augment

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

Implant components and methods

A variable angle blade augment including an augment section and a separate plate or blade segment. According to some embodiments, a first connector of the blade segment and a socket capture mechanism of the augment section provide a ball and socket type joint. Additionally, the socket capture mechanism may be structured to allow for linear displacement of the first connector relative to at least one axis of the socket capture mechanism. By allowing for at least pivotal and linear relative displacement of the augment section and the blade segment, the variable angle blade augment may improve the ability to optimally position a buttress augment against a prosthetic acetabular shell. Moreover, the variable angle blade augment may provide the ability to utilize components of an implantable medical device after stabilizing the components to a bone structure of a patient.

An apparatus () for removing bone material comprises a distal cutting instrument () and a proximal cutting instrument (). The distal cutting instrument has at least one first cutting edge (), a shoulder (), and a shaft portion (). The shaft portion () has an anti-rotation feature. The at least one first cutting edge () removes bone material when moved in a first direction. The proximal cutting instrument () is removably attached to the shaft portion (). The proximal cutting instrument () has a first end portion () and a second end portion (). The second end portion () contacts the shoulder () of the distal reamer () when the proximal reamer is mounted to the shaft portion (). The proximal reamer () has at least one second cutting edge () and an aperture. The aperture is adapted to receive the anti-rotation feature of the shaft portion () of the distal reamer (). The at least one second cutting edge () removes bone material when moved in a second direction.

Femoral reaming system and method of performing trial reduction

Bipolar prostheses which include various structures and other techniques for optimizing material wear and mechanical strength properties. Such prostheses feature, for example, improved resistance to polyethylene wear while also reducing potential for dislocation of the femoral stem from the prosthesis. Such techniques and structures include varying wear resistance and mechanical strength treatment in various components of the prostheses or portions of those components as desired to improve, accentuate or optimize wear performance and dislocation reduction, locking ring structural features, structures for retaining locking rings in the bipolar prosthesis shell, and structures for limiting or reducing movement or rotation of locking rings and liners in bipolar prosthesis shells.

Hip prostheses

A system () for preparing a long bone for a prosthetic, the long bone having a long axis comprises a distal instrument () and a proximal instrument (). The distal instrument () is configured to remove bone from a distal portion of bone. The distal instrument () has a bone removing portion () configured to remove bone along the long axis of the long bone and a shaft () extending from the bone removing portion () along the long axis of the long bone. The proximal instrument () is configured to overlie the shaft () of the distal element () within the long bone. The distal shaft () guides the proximal instrument () to prepare the proximal portion of the long bone after the distal instrument () has prepared the distal portion of the long bone.

Method and apparatus for preparing bone for a prosthetic device

A reference guide comprising an attachment portion configured to abut with and attach to an anatomical feature such as a bone. The reference guide further comprises a reference indicator that may be formed integrally with, or selectively securable to, the attachment portion and that indicates a reference point with respect to the attachment portion. The reference guide may be used to identify a target location during a surgical procedure even in the absence of traditional landmarks.

Bone preparation reference guide

An intramedullary implant for mounting within an intramedullary canal of a bone is disclosed. The intramedullary implant includes a lower stem portion, an upper stem portion, and a modular sleeve body. The modular sleeve body is connected to one of the lower stem portion or the upper stem portion. The sleeve body includes an inner portion that covers at least a segment of the upper stem portion and has one or more longitudinally extending bone engagement members for engagement with the bone.
