Is this brace right for me?
The DonJoy Performance Bionic™ Elbow Brace II delivers maximum support for athletes managing ligament instability, hyperextension risk, or recovering from injury from contact and repetitive-motion sports. This brace combines rigid polycentric hinges, adjustable extension-control straps, and compression neoprene into a stabilizing support system. Dual bilateral polycentric hinges resist the side-to-side forces that strain the UCL and RCL with every throw, tackle, or swing. Adjustable non-stretch X-straps layer over the hinge system to set a precise mechanical extension limit, stopping the joint before it reaches painful lock-out angles. Breathable perforated neoprene delivers consistent, even compression across the elbow to help reduce swelling while managing heat buildup. Internal hex silicone banding prevents the brace from shifting during heavy use. An ergonomic elbow-crease cutout eliminates fabric bunching at the bend so movement stays clean, comfortable and unrestricted. The result is a low-profile, athlete-grade brace that fits under equipment while delivering the structural support of a clinical-grade hinged device.
Ideal for:
- Contact sports like football, rugby, and wrestling
- Overhead throwing like baseball and softball
- Returning to training after UCL, RCL, or hyperextension injuries
- Managing chronic elbow instability
- Athletes wearing equipment requireing a low-profile brace
