The pathway is located inward of an outer periphery of the helical structure, e.g., adjacent to an inner periphery of the helical structure. The pathway extends in a space between successive portions of the helical structure. The prosthesis assembly includes a locking device () that has a support member and an arm () I/O that projects away from the support member. The arm is configured to be disposed in the pathway when the support member is disposed adjacent to the second end of the base member. The arm is disposed through bone in the space between successive portions of the helical structure when the prosthesis assembly is implanted.

An instrument used for the implantation of a glenoidal prosthetic component is disclosed. A relative position of a glenoidal prosthesis component and of a plate is adjustable around an implantation axis before fixing the assembly. The instrument comprises a tool for positioning the glenoidal prosthetic component and the plate relatively to each other angularly around the implantation axis. The instrument includes a tool that has a body, which, in use, extends transversely to the implantation axis and which is provided with localization elements for localizing an implantation angle centered on the implantation axis, so that the tool is able to intra-operatively protract the implantation angle with respect to the glenoid.

Instrumentation and method for implanting a glenoidal prosthetic component on a glenoid

The glenoid implant comprises a baseplate, an articular component which has a convex articular surface, and a platform which is provided both to be secured to the articular component by a first attachment and to be secured to the baseplate by a second attachment, the first attachment being independent from the second attachment and defining an assembly axis along which the platform and the articular component are assembled together. The first attachment comprises both a translational connection that is intraoperatively operable to prevent translation between the platform and the articular component along the assembly axis, and a rotational connection that is intraoperatively operable to prevent rotation between the platform and the articular component around the assembly axis, the translational connection and the rotational connection being distinct from each other. The glenoid implant allows assembling the platform indifferently with one of various articular components which differ from each other for example by their material composition and/or by some geometric features of their convex articular surface and/or etc. The articular component that is effectively assembled with the platform can be chosen by the surgeon during surgery, i.e. during an implantation operation or just before the latter.

Glenoid implant for a shoulder prosthesis, and set for assembling such a glenoid implant

A surgical shoulder articulation replacement method is provided. The method can include providing a humeral implant having a hollow stem. The hollow stem can be provided with a sharp distal edge. The method can include impacting the humeral implant in a cancellous bone of a humeral head of a patient, with the sharp distal edge cutting the cancellous bone in the process.
