An implant extractor assembly that includes a handle, and a mount connectable to the handle. The mount includes a main body, a quick connect about a proximal end of the main body, and an L-shaped connector about a distal end of the main body. The L-shaped connector includes a through hole having a longitudinal axis transverse to a longitudinal axis of the main body.

The present invention relates to a shoulder prosthesis comprising:a metaglene element (2) or baseplate;a pin (3) projecting from said metaglene element (2);a through-hole (11) in the centre of said metaglene element (2);at least one through-hole (5) formed in a periphery of the metaglene element (2) with respect to said central through-hole (11);a glenosphere element (12) opposite said pin (3) with respect to said metaglene element (2);a central compression screw (9) housed in said through-hole (11) in the centre of said metaglene element (2) and having a head abutting onto the bottom of said hole (11); andwherein the central through-hole (11) has an opening (11A) that is threaded in a stretch to receive the end of a safety screw (18) passing through the glenosphere element (12);a connector element (13) between the metaglene element (2) and the glenosphere element (12), the metaglene element (2) providing a seat (14) for housing the connector element (13) projecting around the central through-hole (11).

A surgical procedure method includes accessing an implanted joint prosthesis having an implant engaged within a bone of the joint and a first articulating component mounted by a first mating component to a first insert component removably mounted to the implant, and partially disassembling the accessed implanted joint prosthesis by removing the first insert component with the first articulating component fixed thereto from the implant while the implant is engaged with the bone. The angular position of the first mating component with respect to the first insert component is then determined and replicated with a second insert component and a second mating component. The second insert component and the second mating component are then fixed at the replicated angle and the fixed second insert component and second mating component are mounted to the implant engaged within the bone. A new articulating component is then mounted to the second mating component.

The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally, the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removably locks or helps to removably lock or fix the quasi-spherical member in the bore.

Embodiments of an implant assembly for reverse shoulder arthroplasty is disclosed. In one embodiment, the implant assembly comprises a humeral component and an adaptor coupled to the humeral component. The humeral component comprises a stem portion and a neck portion. The stem portion is configured for fixation to a humerus, and the neck portion is angularly oriented relative to the stem portion. The adaptor comprises a first bearing surface and a second bearing surface opposite the first bearing surface. The first bearing surface interfaces with an articulating surface of the neck portion to allow the adaptor to rotate relative to the humeral component in a plane that is generally parallel to the articulating of the neck portion. The second bearing surface is configured to interface with a glenosphere component to allow the glenosphere component to articulate relative to the adaptor.

An anchoring stem for a joint prosthesis with a centromedullary fixation includes a metaphyseal-diaphyseal (M-D) portion intended to be inserted into the medullary canal of the long bone of the joint to be prosthesized. It receives an epiphyseal-diaphyseal (E-D) portion, having its upper portion protruding from the considered bone and intended to receive in turn an articular element. The M-D portion and the E-D portion are independent from each other but may be fastened to each other. The E-D portion is received within the M-D portion along a direction parallel or substantially parallel to the main dimension of the M-D portion, along a length of cooperation of the portions with each other such that the ratio of the length of reception of the E-D portion within the M-D portion to the total length of the M-D portion is in the range from 0.5 to 0.85. The M-D portion is provided with means capable of forbidding any rotation or angular displacement of the E-D portion once the latter has been received within the M-D portion.

A method for preparing an articulating component of a joint prosthesis, the prosthesis having an implant engaged within a bone of the joint, the method including inserting a first articulating component into a first insert in the implant within the bone of the joint, determining an angular orientation of the inserted first articulating component relative to the implant within the bone of the joint, positioning a second articulating component within a second insert component, replicating the angular orientation of the first articulating component in the second articulating component positioned within the second insert, fixing the second articulating component to the second insert component at the replicated angular orientation, and mounting the second insert component with the fixed second articulating component to the implant engaged within the bone of the joint.

A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device.
