Hintermann Series H3™
Total Ankle Replacement (TAR) Prosthesis
(formerly known as HINTEGRA TAR prosthesis)

The Hintermann Series H3™ Total Ankle Replacement prosthesis (formerly known as HINTEGRA TAR prosthesis) is a non-constrained, three-component total ankle replacement system consisting of a tibial implant component, a talar implant component, and an ultra-high molecular weight polyethylene mobile bearing insert (PE inlay). The tibial and talar implants can also be custom-manufactured in an alternative material for patients who are sensitive to Cobalt-Chrome (CoCr) alloys.
Currently, this product is only available outside of the United States.

The tibial implant is comprised of a flat-loading plate and an anterior shield. The anatomically shaped flat surface allows for optimal contact with the subchondral bone of the entire resected tibia, including the cortical rim of the metaphysis to maximize the load transfer area without creating stress shielding. The tibial implant is available in seven sizes 0-6.

The talar implant is conically shaped to mimic the anatomic shape of the talus. Rims are provided on each side of this implant to provide mediolateral stability to the PE inlay bearing and to serve as a guide for anteroposterior translation. Polished overhangs on the medial and lateral side serve as anatomical articular surfaces. The talar implant is available in seven sizes 0-6.

The PE inlay provides a flat planar surface to interface with the polished flat plane of the tibial implant and a concave surface to interface with the anatomically oriented polished surface of the talar implant. The PE inlay is available in four thicknesses (5, 6, 7 and 9mm) and matched sizes 0-6 to either orientation (right/left) of the prosthesis.
