Revision implant augments, systems, and methods
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 revision implant component, comprising:
a tapered body shaped and dimensioned to substantially align with a top surface of a resected talus, the body including an inner side and an outer side and defining a plurality of screw holes with a plurality of polyaxial locking tabs disposed about the circumference of the plurality of screw holes, and a head configured to engage a talar dome component of a multi-component ankle prosthesis.
2. The revision implant component of claim 1 , wherein the body is shaped and dimensioned to substantially align with a bottom surface of a talar dome.
3. The revision implant component of claim 2 , wherein the head is shaped and dimensioned as a Morse taper.
4. The revision implant component of claim 3 , wherein the head defines a recess and a notch.
5. The revision implant component of claim 4 , wherein the body further defines at least one wire hole.
6. 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; and
coupling the revision implant component to a talar dome of the multi-component ankle prosthesis,
wherein the revision implant component has a tapered body shaped and dimensioned to substantially align with a top surface of a resected talus, the body including an inner side and an outer side and defining a plurality of screw holes with a plurality of polyaxial locking tabs disposed about the circumference of the plurality of screw holes, and a head configured to engage a talar dome component of a multi-component ankle prosthesis.
7. The surgical method of claim 6 , further comprising resecting damaged bone prior to the step of affixing a revision implant component to non-damaged bone using screws.
8. The surgical method of claim 7 , wherein the revision implant component is affixed to non-damaged bone using screws with threaded heads.
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 9 , wherein the screws are affixed to the revision implant component and non-damaged bone of the calcaneus or navicular.
11. The surgical method of claim 10 , wherein the step of coupling the revision implant component to a talar dome further comprises attaching an augment between the revision implant component and the talar dome.
12. The surgical method of claim 7 , 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.
13. The surgical method of claim 7 , wherein the revision implant component is coupled to the component of the multi-component ankle prosthesis in situ.
