Dr. Beat Hintermann, Chairman of the Clinic for Orthopaedics and Traumatology at Kantonsspital Baselland in Liestal, Switzerland, developed the Hintermann Series H3 non-constrained TAR prosthesis more than 20 years ago and has seen continued success in the global marketplace. He then developed the Hintermann Series H2 semi-constrained option for patients in order to expand indications and patient selection for total ankle replacements.

With the Hintermann Series Total Ankle Replacement System, surgeons will now have an opportunity, using a single instrument set, to offer a full solution to their patients using the H2 and H3 to perform primary (H2 and H3), revision (H2), or take-down TARs (H2 and H3).

After implantation, the Hintermann Series H2 is constrained in a patient-specific optimized position to further support the surrounding tissues, providing stability against translational and rotational forces of the normal ankle joint. This device utilizes the identical surgical preparation and approach as the Hintermann Series H3, including the instrumentation.
