The Hintermann Series H2 Total Ankle Replacement (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.
The Hintermann Series H2 is indicated as a total ankle replacement in primary or revision surgery of ankle joints damaged by:
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.
Indications for use as stated in the FDA summary.
