Revision implant augments, systems, and methods
View Patent ↗A revision implant component comprising a body having a plurality of screw holes and a tapered head configured to engage a talar dome component of a multi-component ankle prosthesis. A surgical method is disclosed which includes creating an incision in a patient, exposing a multi-component ankle prosthesis implanted in a patient, disassembling at least one component of the multi-component ankle prosthesis, affixing a revision implant component to non-damaged bone using screws, and coupling the revision implant component to a talar dome of the multi-component ankle prosthesis.
1. A surgical method, comprising:
creating an incision in a patient;
exposing a multi-component ankle prosthesis implanted in a patient;
disassembling at least one component of the multi-component ankle prosthesis;
affixing a revision implant component to non-damaged bone using screws with threaded heads, wherein the screws are affixed to the revision implant component and non-damaged bone of the navicular;
coupling the revision implant component to a talar dome component as a revision of the multi-component ankle prosthesis; and
resecting damaged bone prior to the step of affixing the revision implant component to non-damaged bone using screws,
wherein the revision implant component has a body including a head configured to engage a feature of the talar dome component for coupling the revision implant component to the talar dome component.
2. The surgical method of claim 1 , wherein the screws are affixed to the revision implant component and non-damaged bone of the talus.
3. The surgical method of claim 1 , wherein the screws are affixed to the revision implant component and non-damaged bone of the calcaneus.
4. The surgical method of claim 1 , wherein the step of coupling the revision implant component to a talar dome component further comprises attaching an augment between the revision implant component and the talar dome component.
5. The surgical method of claim 1 , wherein the step of affixing the revision implant component to non-damaged bone further comprises attaching an augment between the revision implant component and the non-damaged bone.
6. The surgical method of claim 1 , wherein the revision implant component is coupled to the talar dome component in situ.
7. The surgical method of claim 6 , wherein the head is a Morse taper.
8. A surgical method, comprising:
creating an incision in a patient;
exposing a multi-component ankle prosthesis implanted in a patient;
disassembling at least one component of the multi-component ankle prosthesis;
resecting damaged bone adjacent to the at least one disassembled component of the multi-component ankle prosthesis;
selecting a revision implant component from a kit containing a plurality of a revision implant components based on the desired thickness of the selected a revision implant component as a function of the depth of bone resected;
affixing the revision implant component to non-damaged bone using screws, wherein the screws are affixed to the revision implant component and non-damaged bone of the navicular; and
coupling the revision implant component to a talar dome component as a revision of the multi-component ankle prosthesis,
wherein the revision implant component has a body including a tapered head configured to operatively connect with the talar dome component of the multi-component ankle prosthesis.
9. The surgical method of claim 8 , wherein the screws are affixed to the revision implant component and non-damaged bone of the talus.
10. The surgical method of claim 8 , wherein the screws are affixed to the revision implant component and non-damaged bone of the calcaneus.
