Implantable shoulder prostheses
Prosthesis, tools and surgical methods treat joint instability by avoiding loosening over time. A shoulder prosthesis includes a humeral member with a humeral joint surface and a humeral fixation member and a glenoid member comprising a glenoid body with a glenoid joint surface, and a glenoid fixation member attaching the glenoid body to a scapula. The glenoid fixation member may be attached orthogonally to the scapula. A dampener may be included to absorb loads that may loosen one or more components of the prosthesis.
1. A method of securing an implantable shoulder prosthesis comprising:
initially securing at least one fixation member of a glenoid member to a scapula of a patient, the glenoid member including a penetrable, re-sealable septum; and
delivering injectable material via the septum into at least one transport tube of the glenoid member, wherein the delivering of the injectable material is performed at least twenty four hours after the initial securing of the at least one fixation member.
2. The method of claim 1 wherein the delivering of the injectable material causes the injectable material to exit at least one output port of the at least one fixation member.
3. The method of claim 1 wherein the glenoid member comprises an articulation surface and an opposing surface, and wherein the delivering of the injectable material causes the injectable material to exit at least one output port positioned on the opposing surface.
4. The method of claim 1 further comprising expanding the fixation member.
5. The method of claim 4 wherein the expanding of the fixation member is performed at least twenty four hours after the initial securing of the at least one fixation member.
6. A method of securing an implantable shoulder prosthesis comprising:
initially securing at least one fixation member of a glenoid member to a scapula of a patient, the glenoid member including a penetrable, re-sealable septum; and
delivering injectable material via the septum into at least one transport tube of the glenoid member; and
expanding the fixation member, wherein the expanding of the fixation member is performed at least twenty four hours after the initial securing of the at least one fixation member.
7. The method of claim 6 wherein the delivering of the injectable material causes the injectable material to exit at least one output port of the at least one fixation member.
8. The method of claim 6 wherein the glenoid member comprises an articulation surface and an opposing surface, and wherein the delivering of the injectable material causes the injectable material to exit at least one output port positioned on the opposing surface.
