Abstract
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.
Claims13
A revision implant component, comprising:
- a narrowing body dimensioned to substantially align with a top surface of a resected talus and a talar dome component, the body including an inner side and an outer side and defining at least one screw hole with a plurality of polyaxial locking tabs disposed about the circumference of the at least one screw hole, and a head configured to engage the talar dome component.
A surgical method, comprising:
- creating an incision in a patient;
- exposing an ankle prosthesis implanted in a patient;
- disassembling at least one component of the 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 ankle prosthesis, wherein the revision implant component has a narrowing body dimensioned to substantially align with a top surface of a resected talus, the narrowing body including an inner side and an outer side and defining at least one screw hole with at least one polyaxial locking tab disposed about the circumference of the at least one screw hole, and a head configured to engage a talar dome component of an ankle prosthesis.
