A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.

A two piece humeral component for use in joint arthroplasty which is adapted to be implanted into a joint and engaged by a socket component of the joint. The joint component includes a body having a first articulating surface and a second medial surface opposite the first articulating surface. The first articulating surface is adapted to be engaged by the socket and the second medial surface is adapted to be secured to mounting portion. The mounting portion has a first surface and a second medial surface. The first surface is adapted to be fixably engaged to the second mounting portion of the humeral component. The second medial surface is adapted to be secured to the humerus. A peg which has a first end adapted to engage a cavity found in the humerus is disposed on the mounting portion's second medial surface.

This invention provides optimized solid substrates for promoting cell or tissue growth or restored function, which solid substrate comprises aragonite and is characterized by a specific fluid uptake capacity value of at least 75%, or a contact angle value of less than 60 degrees when in contact with a fluid and which is further characterized by tapered sides and tools for implantation of optimized solid substrates.

Methods for supporting a prosthetic implant in a patient are disclosed. In some embodiments, a hollow sleeve and a prosthetic implant with a stem component are implanted in a cavity in an end of a bone where the hollow sleeve provides an axial channel that extends through the length of the hollow sleeve for receiving the stem component. In some embodiments, the hollow sleeve is capable of being impacted into the cavity for obtaining a press fit of the hollow sleeve in the cavity. In some embodiments, the hollow sleeve is formed with a porous material.

Prosthetic component provided with a stem, adapted to be implanted in use at a bone of a patient, such as for example a tibial and/or femoral component of a knee prosthesis or a femoral component of a hip prosthesis or a humeral component of a shoulder prosthesis, or a component of an elbow prosthesis, including a device adapted to externally cover and/or to house at its interior at least the stem of the prosthetic component, wherein the device is in use placed between the prosthetic component and the bone of the patient, suitable to stably constrain in use the prosthetic component to the bone of the patient and to prevent the direct contact between prosthetic component and bone of the patient.
