Inner Head Ø28,32,36

Description

The Inner Head Ø28, Ø32, Ø36 is a critical component for modular hip arthroplasty, designed for seamless integration with bipolar hip systems, total hip replacement (THR) constructs, and modular femoral stems. These inner heads are precision-engineered to serve as the primary articulating surface, ensuring fluid joint motion and anatomical restoration of the hip’s center of rotation.

Available in three industry-standard diameters—28mm, 32mm, and 36mm—these heads allow surgeons to select the optimal size based on the patient’s acetabular dimensions and the desired range of motion. Larger diameters, such as the 36mm variant, are specifically designed to enhance joint stability and significantly reduce the risk of post-operative dislocation. Each head is meticulously machined to ensure a perfect taper fit with femoral stems, providing a secure, vibration-free connection that minimizes the risk of fretting or corrosion.

Key Features & Benefits

• Versatile Diameter Options: Available in 28mm, 32mm, and 36mm to accommodate varied patient anatomies and surgical requirements for both primary and revision procedures.

• Superior Articulation Geometry: Precision-machined to sub-micron tolerances, ensuring an ultra-smooth surface that reduces frictional torque and minimizes polyethylene wear.

• Advanced Material Science: Manufactured from orthopedic-grade materials—including high-strength Stainless Steel, Titanium alloy, or Cobalt-Chrome—to provide maximum hardness and long-term biocompatibility.

• Stable Modular Engagement: Designed for a secure locking interface with femoral tapers and bipolar shells, ensuring a stable construct under high physiological loads.

• Enhanced Joint Stability: The availability of larger head sizes (32mm/36mm) provides an increased “jump distance,” helping to prevent impingement and dislocation during extreme ranges of motion.

Primary Clinical Applications

• Total Hip Arthroplasty (THA): Functions as the femoral articulating component when paired with a compatible acetabular liner.

• Bipolar Hemiarthroplasty: Serves as the internal articulating head within a bipolar shell for the treatment of femoral neck fractures in elderly or low-demand patients.

• Modular Hip Revision: Allows for the adjustment of neck length and head size without the need for full stem removal, facilitating intraoperative flexibility.
