Radial Head Replacement System
The Radial Head Replacement System allows for direct and radiographic visualization of the radiocapitellar, proximal radio-ulnar, and ulno-humeral joints during trialing.Clear visualization with Radiolucent Trials ensures that the chosen implant allows for a degree of play within the radial neck, helping the implant remain centered during elbow motion. In addition, single-use instrumentation allows for efficiency and cost savings.1, 2, 3, 4
Features & Benefits
Radiolucent Color-Coded Plastic Trials
- Designed for better visualization of proximal ulna and joint1
- Allow for in-situ height determination without repeated removal of trial stems1
- Facilitate increased visibility1
Sterile Single-Use Instrument Kits
- Aim to improve efficiency, reduce costs, and minimize delays3, 5-8
- May translate to less time spent pre-operatively searching for equipment7
Smooth Stem Design
- May enhance the implant’s ability to self-align and “dial in” when the elbow goes through a range of motion and may articulate with the capitellum throughout the entire arc of motion9,10
- Associated with less removal due to implant loosening than press-fit implants11-18
