Hintermann
Series H2®
Total Ankle Replacement
2-COMPONENT, SEMI-CONSTRAINED IMPLANT
The Hintermann Series H2® is indicated as a total ankle replacement (TAR) in primary or revision surgery of ankle joints damaged by: Systemic arthritis of theankle (e.g., rheumatoid arthritis, hemochromatosis), Primary arthritis (e.g., de-generative 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 an ankle arthrodesis, provided sufficient bone stock is present.
About the Hintermann Series H2 TAR System
Designed to Address Ankle Instability
Tibial Component
Locking mechanism designed to provide patient specific PE inlay positioning and fixation
Low profile anterior shield is designed to:
● Provide rotational stability of tibial component
● Prevent scarring and bone formation that may hinder joint motion
Superior peaks for anchoring in subchondral bone to increase stability in translation and rotation
Sizes 2 – 6 in right or left orientation
Poly (PE) Inlay
Ultra-high molecular weight polyethylene, UHMWPE
Designed for optimal placement and fixation in anterior, posterior, and neutral axis position
High congruency with the frusto-conical bearing surface of the talar components aims to:
● Minimize and distribute contact stresses
● Minimize wear
Sizes 1-6 in right or left orientation
Four thicknesses (5, 6, 7, and 9 mm)
Three offsets (anterior, neutral, and posterior)
Talar Component
Medial and lateral rails facilitate anatomic movement of the PE inlay
● Allow physiological talar motion through dorsiflexion and plantarflexion
● Minimize excessive loading to soft tissue due to anatomic motion
Anterior pegs to improve sagittal stability and positioning
A flat cut talar option is available for patients with lower bone stock
Sizes 1 – 6 in right or left orientation
A Serious Upgrade to the Hintermann Series
OPTIX™ H2 Patient Specific Instrumentation System is a patient specific surgical planning and instrumentation to assist in the positioning of total ankle replacement components intraoperatively, and in guiding bone cutting.
Through the combination of 3D engineering and the patient’s own CT scan, a patient-specific preoperative plan is developed and tailored to fit surgeon preferences. Implant sizing and alignment are determined using the patient’s anatomic landmarks, and DuraForm® PA (nylon) Preoperative Navigation Cut Guides are then created which set resection guide locations.
Reduced Surgical Procedural Complexity
Decreased Operating Time
Rapid 3D Printing Technology - From CT Scan to Surgey in 4 weeks
A History of Clinical Excellence
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.
