Description

EXOS Thumb Spica Fracture Brace with BOA® (Thermoformable Cast Splint)

A reformable, water-resistant thumb spica fracture brace that delivers cast-like stabilization with the convenience of adjustability. Designed to stabilize the thumb (adduction), 1st MCP & 1st CMC joints, while also supporting the wrist joint complex.

Why clinicians and patients choose EXOS
  • Thermoformable (reformable) for a custom fit and better immobilization
  • BOA® micro-adjustable dial helps accommodate swelling/atrophy and fine-tunes compression
  • Water-resistant materials for day-to-day life (dry after wet exposure)
  • Lightweight & adjustable—one brace throughout treatment (reduces waste)
  • Latex-free

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®)

Best for: thumb injury plus needing more wrist/forearm control.

Exos Long Thumb Spica II with BOA — thermoformable wrist and thumb cast splint for scaphoid fractures and CMC arthritis
Primary differences/uses:
  • More forearm length = helps limit wrist motion more.
  • Often chosen for scaphoid (navicular) concern or when wrist stability matters.
  • 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.

Exos brace Available in black only
Primary differences/uses:
  • Designed for fracture-style immobilization of wrist + thumb.
  • More accommodating for swelling and bulky dressings early on.
  • Commonly used when there's a distal radius/ulna wrist-area injury.
  • Often selected for acute injury and some post-op situations.

Size Chart & Fit Tips (Most Returns Are From Sizing)

How to measure: Wrap a soft tape loosely around your hand at the measurement point shown in the diagram. If you measure between sizes or prefer a roomier fit (or expect swelling), size up. This brace can be molded for a better fit.

Fit note: A "perfect shoe-like fit" is not the goal—this is a medical brace designed to accommodate swelling and be molded. If you're on the low end of the range, you may have extra room until molded; if you're on the high end, it should feel more "true to size."

Heating & Application (Important)

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.
