Abstract
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.
Claims13
A method for supporting a prosthetic implant and restoring lost bone stock in a cavity in an end of a bone of a patient, the method comprising:
- implanting a first curved support member, a second curved support member, and a prosthetic implant with a stem component in a cavity in an end of a bone of a patient with the first curved support member and the second curved support member being arranged together to create a prosthetic implant support structure with an axial channel that extends through the length of the support structure and through which the stem component of the prosthetic implant is received for supporting the prosthetic implant in the cavity in the end of the bone, wherein the first curved support member and the second curved support member each are formed with a porous metal material that is a bone ingrowth-receptive material with a porous structure for encouraging bone ingrowth and attachment throughout the first curved support member and the second curved support member for restoring lost bone stock in the patient.
