EXOS Radial Gutter Fracture Brace with BOA — Cast Splint for 2nd & 3rd Metacarpal Fractures
A reformable, water-resistant fracture brace (cast splint alternative) designed to stabilize the 2nd and/or 3rd metacarpal (MC) bones and the respective metacarpophalangeal (MCP) joints of the hand. Ideal for metacarpal fractures when immobilization is prescribed.
Why clinicians choose EXOS for radial gutter immobilization
- Thermoformable / remoldable for a custom fit during swelling changes
- BOA Fit System for micro-adjustable compression and quick on/off
- Radial gutter design supports 2nd/3rd digits and helps position MCP joints for stability
- Water-resistant & easy to clean (hand wash / dry; hair dryer is commonly used for drying)
- Radiolucent material (often allows imaging without removal, per clinical protocol)
- Not made with natural rubber latex
Indications
- Fractures of the 2nd and/or 3rd metacarpal (MC) bones
- Injuries to the respective metacarpophalangeal (MCP) joints
- Injuries requiring radial gutter immobilization per provider direction
