A glenoid implant includes a body, a plurality of fins, a collet, and a plug. The body has a central aperture therethrough and a plurality of slots. Each of the plurality of fins are coupled with a respective one of the plurality of slots of the boss of the body such that each of the plurality of fins is configured to move from a first generally inward position towards a second generally outward position. The collet including an interior threaded bore and a plurality of deflectable arms. The plug includes a threaded portion and a tip portion configured to engage with and cause the plurality of deflectable arms of the collet to move and cause the plurality of fins to move from the first generally inward position towards the second generally outward position, thereby aiding in securing the body to a scapula of a patient.

The invention concerns a tibial prosthetic component comprising a plate (100) for forming a tibial plateau of a tibia (16), wherein a peripheral region of the plate (100) has a thickness of less than 3 mm. The invention also concerns a tibial prosthetic component having a keel of depth less than 9 mm. The invention also concerns a method of selecting a tibial prosthetic component comprising receiving measurements of at least one physical attribute of an individual into whom the tibial prosthetic component is to be implanted, selecting a thickness of a plate (100) and depth of keel of the tibial prosthetic component based on the measurements and providing a tibial prosthetic component comprising a plate (100) having the selected thickness and a keel having the selected depth. The invention may also comprise implanting a tibial prosthetic component selected in accordance with this method into an individual and a kit comprising a plurality of prosthetic components comprising plates having different thicknesses with keels of different depths.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

A prosthesis, in particular a shoulder prosthesis, includes a socket part receiving a joint head; an anchoring part anchoring the prosthesis in a bone; and a connecting arrangement securely connecting the socket part to the anchoring part. The socket part is assigned at least one pin and the anchoring part has at least one guide. The guide is designed in such a way that the pin can be held substantially safe from tilting in the guide.

Disclosed are prosthesis systems and methods that provide ways by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

A glenoid baseplate, for an artificial shoulder joint, includes: a base having a fixing hole formed so as to insertedly accommodate a fixer; an insertion part extending at a predetermined angle from the base; and a recessed part made by forming a recess in a part of one surface of the base which is located a predetermined distance from at least a central fixing hole, a peripheral fixing hole, and the edge of the base. The base includes: the central fixing hole formed vertically through the base; and the peripheral fixing hole formed in the periphery of the central fixing hole. The insertion part includes a shaft extending from the base so as to have a hollow extending from the central fixing hole, the insertion part including: a rib protruding, so as to have a predetermined width, from one base-side end of the shaft to the other end; and a rim protruding from the shaft.

A device for anchoring a shoulder prosthesis in a reverse configuration includes a baseplate delimited at the bottom by a first at least partially convex surface, and at the top by a second concave surface, opposite the first surface, and peripherally by a third truncated-cone or cylindrical surface; and a central pin, protruding from the first surface at a first end thereof, and defining an axially pass-through inner duct having at least one main diameter. The central pin has a second free end, opposite the first end. The duct has a helical cavity made in the inner wall delimiting the duct, open towards the inside of the duct and extending along the length of the duct. The inner duct has a secondary diameter smaller than the main diameter, and the helical cavity has a diameter larger than the main diameter of the inner duct.
