Description
EXOS Short Thumb Spica II with BOA - Hand-Based, Heat-Moldable Thumb Brace
The Short Thumb Spica II (STS II) from EXOS by Enovis/DJO is a low-profile, thermoformable thumb support designed to stabilize the thumb's first metacarpophalangeal (MCP) joint. Its hand-based construction supports the thumb without extending up the forearm like a long thumb spica brace.
Features a BOA dial adjustment, adjustable thumb strap, and openings near the thumb base and palmar crease. Available in black, sizes XXS-XL, for left or right hand. A trained healthcare professional should heat-mold and fit the brace.
Common Uses (as Prescribed)
- Stabilization of the thumb's first MCP joint
- Support during preoperative or postoperative care
- Support following selected thumb injuries or trauma
- Support for certain degenerative thumb-joint conditions, as directed by a clinician
Important: Select a brace based on your diagnosis and the exact type prescribed. This short, hand-based model is not interchangeable with an EXOS wrist-and-thumb fracture brace.
Features & Benefits
- Heat-moldable construction: thermoforms around the hand when fitted by a qualified professional.
- BOA® Fit System: permits micro-adjustments to circumferential compression.
- Adjustable thumb strap: customizable fit across the thumb's web space.
- Hand-based design: stabilizes the thumb MCP joint while leaving more of the wrist uncovered.
- Open thumb base and palmar crease: designed to accommodate functional movement where clinically appropriate.
- Material: not made with natural rubber latex, according to Enovis.

Heating & Application - Professional Fitting Required
This brace is not ready to wear as a molded orthosis straight from the package. A qualified healthcare professional should heat and mold it to the patient's hand and thumb. Do not judge final fit before molding.
| Requirement | Enovis Instruction |
|---|---|
| Specified heating temperature | 200°F (93°C) |
| EXOS oven heating time | Approximately 3 minutes, or until pliable |
| Maximum temperature | Never exceed 212°F (100°C) |
| Safety | Never heat while worn; confirm it is not too hot before application. Follow the manufacturer's instructions. |
Before heating: check the received model, size, side, condition and manufacturer's instructions.
Read EXOS Short Thumb Spica II official Instructions for Use (PDF). Also see our EXOS Brace Fitting & Heating Guide; it discusses a separate OrthoTape water-bath method that is not an Enovis-validated heating procedure.
EXOS Return Restriction: Once an EXOS brace has been heated, molded, worn, or altered, it is not eligible for return. Please inspect the model, size and side before fitting. Unused-product eligibility is governed by OrthoTape's return policy.

These are different supports. Select the model recommended by your clinician; a short thumb brace is not a substitute for a fracture brace when wrist immobilization is required.
