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

SYSTEM FEATURES AND KEY BENEFITS
Anatomic design of components
Intended to offer anatomic loading (non-stress shielding) at all bone-implant interfaces
Size matched UHMWPE inlay assembly in 4 different thicknesses and anterior/neutral/posterior offsets
Tibial and talar components are designed with a Plasma Titanium coating intended for cemented use only

Designed to Address Ankle Instability

EXPANDING INDICATIONS AND PATIENT SELECTION FOR TAR

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
