Radial Head System: The Market Leader Now with plating options: introducing the EVOLVE® TRIAD™ Radial Head and Radial Neck Plates. Radial Head Plate Radial Neck Plate EVOLVE® PROLINE Radial Head System • Over 35,000 implanted1 • Independently studied: non-design team JBJS study from Oulu, Finland concludes that smooth stems and cemented bipolar designs should be considered superior to press-fit prosthesis2 • Smooth stem implant designs supported by two long term studies (12-year3 and 8-year4 average follow up) • Prospective data shows proven performance in two-year outcomes5 • Press-fit ingrowth designs have been shown to experience symptomatic loosening6 • Smooth stem design avoids ingrowth, and thereby avoids the need for a tight fit in fractured bone • Smooth stem design allows for dynamic adjustment, a biomechanical design rationale chosen because: EVOLVE® TRIAD™ Fixation System REFERENCES 1.
