Description
EXOS Hand-Based Ulnar Gutter Brace - Heat-Moldable Splint for 4th and 5th Metacarpals
The EXOS Hand-Based Ulnar Gutter Brace (Enovis / DJO, 125 series) is a custom-fit, thermoformable splint designed to stabilize injuries involving the fourth and fifth metacarpals, their MCP joints, and the ring and little fingers, as prescribed by a healthcare professional. Its compact hand-based shape allows free movement at the wrist, subject to clinical instructions.
Black only. Select the affected left or right hand and sizes XS through XL. Adjustable hook-and-loop straps secure the brace; this 125-series model does not use a BOA dial.
Common Uses (as Prescribed)
- Support for selected 4th and 5th metacarpal fractures (ring- and little-finger side of the hand)
- Stabilization of the corresponding 4th/5th MCP joints and phalanges
- Preoperative, postoperative, and post-traumatic stabilization when a clinician determines this hand-based design is appropriate
- Cases where finger and metacarpal support is needed while preserving wrist range of motion, as directed
A hand-based brace is not interchangeable with a wrist-spanning fracture brace. Match the exact model to the treatment plan prescribed by your medical provider.
Key Features and Benefits
- Thermoformable and reformable: heat-molded to the patient's hand by a qualified healthcare professional
- Ulnar gutter support: shaped for the ring- and little-finger side of the hand; facilitates greater than 70° flexion positioning at the 4th and 5th MCP joints during fitting
- Hand-based profile: maintains free wrist movement where permitted by the treatment plan
- Adjustable hook-and-loop straps: detachable strapping helps adjust the fit to the hand and fingers
- Trimmable by a clinician: as directed by the physician for required range of motion
- Washable material: waterproof brace design; clean and thoroughly dry both skin and brace after exposure to water
- Latex information: not made with natural rubber latex, according to Enovis

The chart reflects Enovis's published U.S. measurements. The XL size begins at 11 inches. For measurements near a size boundary, have your treating healthcare professional verify the correct fit before heating.
Heating, Fitting and Application - Important
Professional heat molding is required for proper application. This is not a conventional ready-to-wear cloth splint. Enovis instructs that the brace be fitted by a qualified healthcare professional.
| Manufacturer Fitting Detail | EXOS Hand-Based Ulnar Gutter Brace |
|---|---|
| Correct heating temperature | 200°F (93°C) in an EXOS oven |
| Heating time | Approximately 5 minutes or until pliable; do not apply while too hot |
| Maximum permitted heat | Do not exceed 212°F (100°C) |
| Application | Never heat on the body. Fit to dry skin, align to the palm, secure hook-and-loop straps and mold as instructed. |
Before heating: Verify the exact brace model, size, side and overall condition. Do not overtighten the straps; excess pressure can injure fragile or compromised skin.
Read the official Enovis Hand-Based Ulnar Gutter Brace Instructions for Use (PDF). You can also review our EXOS Brace Fitting and Heating Guide; any alternate water-bath method described there is not an Enovis-validated heating protocol.
EXOS return restriction: Once an EXOS brace has been heated, molded, worn, or altered, it is not eligible for return. Check the item before fitting. Review OrthoTape's return policy for unused-item eligibility.
