BiPolar
Hip System
Understanding the Bipolar Head
The bipolar head is an advanced component of a total hip replacement, replacing the natural femoral head and working in conjunction with a femoral head implant and hip stem.
Key Components
Highly Polished CoCr Outer Shell: This durable shell articulates with the patient’s preserved acetabulum (hip socket). Polyethylene Insert: Located within the outer shell, this insert articulates with a modular femoral head. Modular Femoral Head (22mm or 28mm diameter): This component is secured within the bipolar head by a pre-assembled retaining ring.
How it Works
The bipolar head features a dual articulation system:
- Outer Articulation: The CoCr outer shell moves against the patient’s natural acetabulum.
- Inner Articulation: The polyethylene insert moves against the modular femoral head.
This design provides enhanced stability and a smoother range of motion.
