The present invention is related to a prosthesis, in particular a revision prosthesis, for repositioning and fixating acetabulum fractures. The prosthesis comprises a cup member (1), a hook member (2) and a hook retraction member (3). The cup member is formed and configured to be fixable into an acetabular cup. The hook member is formed and configured to be fixable onto an edge of the acetabular cup. The cup member and the hook member are formed and configured to be retractable into one another. The hook retraction member comprises at least one cable arranged and configured for retracting the hook member into the cup member.

An adjustable revision guide for femoral resections comprising a translating stem adaptor, a distal end of the translating stem adaptor configured to selectively attach to a femoral trial/resection guide. The translating stem adaptor configured to selectively translate the femoral trial/resection guide proximally-distally. A proximal end of the translating stem adaptor configured to selectively attach to an offset adaptor of an intramedullary rod. The translating stem adaptor configured to allow for selective locking of rotation of the offset adapter on the translating stem adaptor to thereby lock-in a selected offset. A femoral trial/resection guide selectively attached to the distal end of the translating stem adaptor for use in resecting said distal femur. An intramedullary rod attached to the proximal end of the translating stem adaptor via an offset adaptor on a distal end.

A jig for revision surgery includes a body defining a contact surface(s) negatively corresponding to an articular surface of a primary implant. The body is configured to be coupled in a unique complementary coupling via engagement of the contact surface with the articular surface. A cut guide(s) is in the body, the cut guide(s) positioned relative to the at least one contact surface so as to be aligned with an underside of the primary implant or of a revision implant.

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.

Disclosed herein is a kit for augmenting a primary repair construct in an articulating joint. The kit includes a flexible member, a first implant that fixes a first end of the flexible member in a first bone adjacent to the primary repair construct and a second implant that may selectively couple to the flexible member, and thereby fix a second end of the flexible member in a second bone adjacent to the primary repair construct. The kit also includes a tension adjusting construct that may operatively couple to the flexible member and controllable adjust a tension on the flexible member disposed between the first and second implant, the tension adjustable so as to define an angle of joint articulation at which the flexible member changes from being passive to augment the primary repair construct.

A system for monitoring bone ingrowth includes an orthopaedic prosthesis having a circuit configured to transmit force sensor data indicative of an amount of force applied to a stem of the orthopaedic prosthesis in response to receiving power from an external power supply. The force sensor data is indicative of bone ingrowth of the orthopaedic prosthesis. As such, an orthopaedic surgeon may monitored the force sensor data over time to ensure bone ingrowth of the orthopaedic prosthesis has sufficiently occurred.

A method of forming a bone void for receipt of a prosthesis, comprising the steps of: inserting a stem of a reaming guide assembly into an intramedullary canal of a bone, the reaming guide assembly having first and second reamer guides disposed adjacent to each other, the first and second reamer guides being connected to an end of the stem; reaming the bone through the aperture of the first reamer guide to form a first bone void; inserting the lobe trial into the first bone void; and reaming the bone through the aperture of the second reamer guide to form a second bone void.

Provided is a method of assembling an articular component of a prosthetic shoulder joint. The method includes: engaging an end of a coupler of a joint implant with a coupling portion of another component of the joint implant; providing relative rotation between the end of the coupler and the coupling portion of the other component of the joint implant along a continuous range of rotational positions while the end is engaged with the coupling portion of the other component of the joint implant; selecting an amount of eccentricity corresponding to a position within the continuous range of rotational position; and securing the other component of the joint implant to the end of the coupler at the selected amount of eccentricity.

A revision instrument for positioning and securing an intervertebral implant in an intervertebral space between vertebrae is provided. The revision instrument includes a shaft having a body extending from a first end to a second end. A first port and a second port extend through the body of the shaft and a connection tool having a first end and second end is positioned within the first port. The connection tool extends through the first end of the shaft through the second end of the shaft. The first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant. The second port is configured to receive an expansion driver for expanding or compressing the expandable implant.

According to one example, a for revision knee arthroplasty is disclosed. According to this example, the method can include shaping a bone of a patient to create one or more recesses therein, selecting a stem provisional, disposing the stem provisional within the one or more recesses, and assembling in vivo the stem provisional with both a first provisional component configured to simulate a shape of one of a tibial tray implant or a femoral implant and a second provisional component configured to simulate a shape of at least one of a sleeve component, a cone component or a keel component of an implant.
