Which Exos Thumb Spica Do I Need?

You may have noticed on our site that there are TWO Exos Thumb Spica braces. If you have a prescription/diagnosis, match what your provider recommended.

Exos Long Thumb Spica II™ (BOA®)

Helpful for thumb base (CMC) pain when wrist movement aggravates symptoms.
Good when your provider wants strong immobilization + extra wrist control.

Exos Thumb Spica™ Fracture Brace

Best for: fracture-style support, especially with swelling/dressings.

Primary differences/uses:

Designed for fracture-style immobilization of wrist + thumb.
More accommodating for swelling and bulky dressings early on.

📐 Sizing Guide — How to Measure

How to measure: Wrap the tape loosely around the widest part of your hand at the knuckles (exclude the thumb), then match your measurement below. Upsizing is recommended if you measure between sizes or prefer a roomier fit.

Common return reason: ordered too small. If you're borderline, it's usually safer to go up (it can be molded to fit).

Heating & Application (Important)

Your new EXOS brace may arrive flat — this is normal.

EXOS is not a conventional pre-shaped ready-to-wear brace. The thermoformable shell is designed to be heated first and then molded around your anatomy. Do not judge the fit before heating.

⚠️ Before heating: confirm the correct model, side, and size.

Once an EXOS brace has been heated, molded, worn, or altered, it is no longer eligible for return. If you are unsure about what you received, contact us before heating.

Important: This brace must be heated to properly mold for best fit. Watch the videos below before fitting.

Requirement	Manufacturer Specification
Ideal Temperature	200°F (93°C)
Maximum Safe Temperature	212°F (100°C)
Heating Time	Approximately 3–5 minutes
Working Time	3–8 minutes before it hardens
Heating Method	Convection oven or hair dryer (for small adjustments)
⚠️ Warning	Never use a microwave or high-heat industrial heat guns.

Important: EXOS braces are intended to be fitted and remolded by trained medical professionals. Heating/molding performed outside medical guidance may affect fit, safety, and warranty coverage. Many have successfully heated these items on their own using a home oven and wrapping the brace in a damp towel, but we cannot cover this under warranty if it is not done by a trained medical professional.

Alternative Home Heating Method — Controlled Water Bath

For users who do not have access to an EXOS oven, OrthoTape has developed a controlled hot-water bath alternative. This is not an Enovis-published protocol and is performed at the user’s own risk. Suggested water temperature: 160°F–170°F (71°C–77°C); do not exceed 180°F (82°C).

Frequently Asked Questions

What is the EXOS Long Thumb Spica II with BOA used for?

It is commonly prescribed for thumb stabilization (adduction) involving the 1st MCP and 1st CMC joints, suspected or confirmed scaphoid (navicular) fractures, thumb and wrist arthritis, pre-op, post-op, post-traumatic, and rehab use. It may also be used for Carpal Tunnel Syndrome in select protocols. Always follow your provider’s prescription.

What is the difference between the EXOS Long Thumb Spica II and the EXOS Thumb Spica Fracture Brace?

The Long Thumb Spica II has more forearm length, providing stronger wrist and forearm immobilization — often chosen for scaphoid fracture concern or when wrist stability is critical. The Thumb Spica Fracture Brace is designed more for fracture-style immobilization and is more accommodating for swelling and bulky dressings in acute injury situations. If you have a prescription, match what your provider specified.

How do I choose the right size?

Measure the circumference around your knuckles (excluding the thumb) with a soft tape. Match to the size chart: XXS (6.5″–7.25″), XS (7.25″–8″), S (8″–9″), M (9″–10″), L (10″–11″), XL (11″+). If between sizes, sizing up is recommended — the most common return reason is ordering too small.

Does it matter if I order left or right?

Yes. This brace is side-specific. Select LEFT or RIGHT to match the injured hand/wrist.

Does the EXOS brace need to be heated?

Yes. EXOS braces are thermoformable and must be heated to mold properly for best fit and safety. The ideal temperature is 200°F (93°C) for approximately 3–5 minutes. Never use a microwave or high-heat industrial heat guns. Heating and molding should be performed by a trained medical professional.

Can I heat the EXOS brace at home without an EXOS oven?

Yes. OrthoTape has developed a controlled hot-water bath alternative for users who do not have access to an EXOS dry-heat oven. The suggested water temperature range is 160°F–170°F (71°C–77°C) — do not exceed 180°F (82°C). This is not an Enovis-published or Enovis-validated water-bath protocol and is performed at the user’s own risk. For full step-by-step instructions, equipment list, safety warnings, and photos, see the EXOS Brace Fitting & Heating Guide.

Does insurance cover this? Can I save vs. my doctor’s office?

This product is HSA/FSA eligible, so you can use pre-tax dollars to purchase it directly. If you have a high DME deductible (common with many insurance plans), you may actually pay less buying here than at your doctor’s office — where the same brace can cost $300–$500 or more. Many clinics also allow you to choose where you purchase your DME items. We recommend checking your plan’s DME deductible before purchasing through your provider.

Perfect brace

After many attempts with poor prostheses, finally found the perfect orthosis. Pain reduction of CRPS from 7-8 to 2-3.
Unfortunately there were problems with the delivery. UPS must do better here.

Cast seams came undone first day I had it on

Cast seams came undone first day I had it on, rather unfortunate because I have used the cast before. It’s an amazing product, I sized it a little big; 6’1” 180lbs, athletic, needed the medium.

Hello. These items have a warranty. We can certainly get you a replacement right way. Very sorry for the issue.

I was pleasantly surprised. It is strong and you can adjust how tight you want to use it. Very good product.
