Bipolar Head
Reliable and Effective Treatment Option for Hip Fractures
Bipolar Head
Partial hip replacement using Bipolar hip systems are a reliable and effective treatment option for hip fractures and diseased femoral heads and/or necks. The Bipolar shell articulates against the host acetabular articular cartilage, preserving acetabular bone stock for future considerations.
The System
- Highly polished cobalt-chromium outer shell
- Preassembled, monoblock construction
- Self-centering design
- Outer diameter size range from 41-46 mm are compatible with 22.2 mm femoral heads
- Outer diameter size range from 47-60 mm are compatible with 28 mm femoral heads
- Various neck lengths available to properly restore joint biomechanics
The Stability
- Recessed head allows for a self-centering design, optimizing load transfer and reducing wear
- Detachable, inner retaining-ring prevents the prosthesis head from dislocating
The Integrity
- Durable connection between polyethylene insert and metal shell prevents micromotion and polyethylene wear
- Polyethylene thickness of at least 5 mm provides excellent wear performance
The Instrumentation
- One instrument tray facilitates operating room efficiency
- Trial shells allow both sizing and trialing, providing adaptability with preferred surgical technique
