The Hintermann Series H2 Total Ankle (Hintermann Series H2) system is designed to treat ankle arthritis through replacement of the ankle joint with a prosthesis, thereby reducing pain, restoring alignment, replacing flexion and extension movement in the ankle joint, and allowing for movement at the replaced joint.

- Systemic arthritis of the ankle (e.g., rheumatoid arthritis, hemochromatosis)
- Primary arthritis (e.g., degenerative disease)
- Secondary arthritis (e.g., post-traumatic, avascular necrosis, provided enough of the talus is preserved to support the implant)
The Hintermann Series H2 is also indicated for patients with a failed previous ankle surgery and revision surgeries following failed total ankle replacement or non-union/mal-union of the ankle arthrodesis, provided sufficient bone stock is present.
Note: In the United States, this device is intended for cemented use only.
