A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

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.

A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

Examples of the invention relate to methods, implants, and instruments for compressing first and second bone portions or a bone portion and an implant together.

This set comprising: an anatomic articulating member, having a concave articulating surface intended to articulate with a complementary humeral implant and having an anatomic coupling feature, a reversed articulating member, having a convex articulating surface intended to articulate with a complementary humeral implant and having a reversed coupling feature that is shaped differently from the anatomic coupling feature, and an anchorage member intended to be anchored in a human glenoid, the anchorage member including a body which defines a proximodistal axis and has inner bore extending along the proximodistal axis, the body being provided within the inner bore with both an inner first feature that is designed to cooperate with the anatomic coupling feature when the anatomic coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the anatomic articulating member, and an inner second feature that is designed to cooperate with the reversed coupling feature when the reversed coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the reversed articulating member, the first feature and the second feature being distinct from each other. The body is operable to be axially introduced into the glenoid before being coupled indifferently with one or the other of the anatomic and reversed articulating members.

A reverse shoulder replacement system including a humeral liner defining a split curvature bearing surface that includes a plurality of curvature regions. The plurality of curvature regions are configured to engage a glenosphere of a glenoid implant individually or in combination to provide an improved fit between the glenosphere and the humeral liner.

The present invention relates to cruciate ligament retaining knee implants, and instruments and methods for implanting cruciate ligament retaining knee implants.

This set comprising: an anatomic articulating member, having a concave articulating surface intended to articulate with a complementary humeral implant and having an anatomic coupling feature, a reversed articulating member, having a convex articulating surface intended to articulate with a complementary humeral implant and having a reversed coupling feature that is shaped differently from the anatomic coupling feature, and an anchorage member intended to be anchored in a human glenoid, the anchorage member including a body which defines a proximodistal axis and has inner bore extending along the proximodistal axis, the body being provided within the inner bore with both an inner first feature that is designed to cooperate with the anatomic coupling feature when the anatomic coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the anatomic articulating member, and an inner second feature that is designed to cooperate with the reversed coupling feature when the reversed coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the reversed articulating member, the first feature and the second feature being distinct from each other.

The body is operable to be axially introduced into the glenoid before being coupled indifferently with one or the other of the anatomic and reversed articulating members.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.
