SYSTEM AND METHOD FOR ANKLE ARTHROPLASTY

摘要

An interpositional arthroplasty system for use in repairing ginglymus joints such as the joints of the ankle, including a tibiotalar implant ( 124 ) that provides a first major surface ( 130 ) adapted to be positioned against a tibia ( 120 ) and a second major surface ( 132 ) adapted to be positioned against a talus ( 108 ) and a polymeric ankle implant that provides a first major surface adapted to be positioned against a talus and a second major surface adapted to be positioned against a calcaneus. Such an implant can be useful for correcting various deformities of an ankle, as well as increasing articulation of a joint. Also described are biomaterials, including polymeric biomaterials having use in preparing such implants, as well as surgical kits that include implants and other tools adapted for their use.
