Abstract
An ankle implant for use in ankle arthroplasty in total ankle replacement is provided. The implant includes an upper prosthesis anchored to the tibia and a lower prosthesis anchored to the talus. The lower prosthesis is operable associated with the upper prosthesis. The implant also includes a stem which is rigidly removably connected to the second member. The stem includes a portion for attachment to the calcaneous. The stem is be adapted to be in a first position in the calcaneous when the stem is in a first relative position with respect to the lower prosthesis, and to provide for a second position in the calcaneous when the stem is in a second relative position with respect to the lower prosthesis.
Claims17
An ankle implant, comprising:
- an upper prosthesis including a body including a tibial stem with a first interlocking component and a concave dome attachable to the tibial stem and configured to articulate with a lower prosthetic body;
- a lower prosthesis including the lower prosthetic body including a talo-calcaneal stem with a second interlocking component and a cap to define an articulating joint surface with the upper prosthesis;
- and
- a plate fixable to a top of a talus and including an overhang portion to overlap both the talus and a portion of a calcaneus.
