A tool assembly for extracting a liner from a prosthesis comprising an impactor and a faceplate. The impactor can be configured to receive and transmit a force. The faceplate can be configured to deliver the force from the impactor to the prosthesis to separate the liner from a shell of the prosthesis.

Systems, devices, and methods are described for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, and an inner surface that interfaces with an implant, the inner surface comprising a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a direction laterally from the port.

A reverse modular humeral implant for implantation into a humerus that includes a natural humeral shaft and a natural humeral head. The implant includes a humeral stem implantable into the natural humeral shaft, and an adapter couplable to the humeral stem, the adapter including an anchoring projection configured to be coupled to a convex bearing.

A method of implanting a shoulder prosthesis in a scapula of a patient includes the step of placing a guide over a primary glenoid component previously implanted within the scapula of the patient. The method further includes the steps of removing the primary glenoid component from the scapula and preparing the scapula for implantation of a secondary glenoid component, wherein the removing and preparing steps occur simultaneously.

A cutting device is provided that includes a pair of cutting blades joined at a pivot point. The cutting blades are driven by an actuator to cause the cutting blades to pivot about the pivot point. The cutting device is configured to remove material underneath a surface of an implant installed on a bone during a revision arthroplasty procedure. The cutting device may travel along a length of the bone just underneath the surface of the implant to remove material and free the implant from the bone. A method for removing material underneath a surface of an implant installed on the bone is also provided. A system for removing material underneath the surface of an implant installed on the bone with the cutting device is also provided.

A surgical device for pin insertion in a bone of a subject to aid in performing a bone cutting procedure is provided that includes a drive portion configured to drive a pin for insertion into the bone. The drive portion has a pin drive assembly with a shaft Q having a shaft proximal end. At least one magnet is associated with the shaft proximal end adapted for attraction and retention of the pin in the shaft proximal end. A spindle assembly is adapted to drive the shaft so as to rotate the pin into the bone to a degree of bone retention that overcomes the attraction and the retention of the pin in the shaft proximal end. An alignment system for surgical bone cutting procedures inclusive of the same is also provided along with a method for aligning a cutting guide on a subject's bone.

Systems, devices, and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, an inner surface that interfaces with an implant and having a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a lateral direction from the port.

A humeral head assembly is provided that includes an articular body and a coupler. The articular body includes a coupling portion disposed on a side of the articular body opposite an articular surface. The coupling portion includes a continuous zone of eccentricity adjustment. The coupler portion optionally includes one or more than one discrete position site. The coupler includes a first portion and a second portion opposite the first portion. The first portion is configured to mate with the coupling portion and the second portion is configured to mate with another member of a joint prosthesis. A coupling portion with the continuous range of eccentricity adjustment can be provided on a bone anchor and the eccentricity of another component can be selected by motion of a coupler, such as a tray for reverse humeral assemblies, along the coupling portion of the anchor.

A modular acetabular cup assembly includes an acetabular cup, and a liner seated in the cup. The cup includes an end face, an apex opposite the end face, and a central axis extending between the apex and a center point of the end face. The liner includes an articular surface having a center of rotation which defines a pivot point of the acetabular cup assembly. In certain embodiments, the pivot point is laterally offset from the center point such that the end face is located between the pivot point and the apex.

A distal femoral joint replacement system includes a femoral component having condylar articular surfaces, a stem extending from the femoral component, and a void filler for filling a bone void within a femur. The void filler includes a body and a plurality of legs extending from the body. The body has a sidewall defining an opening for receipt of the stem which extends along a length of the body and extends through the sidewall so as to form a side-slot in the sidewall that extends along an entire length of the sidewall. The plurality of legs each have a first end connected to the body and a second end remote from the body. The legs each have an outer surface that tapers between the first and second ends and is configured to register with a corresponding inner surface of a bone void when implanted in an end of the femur.
