Thumb Spica Splint

Thumb Spica Splints & Braces

A thumb spica splint immobilizes the thumb and wrist while leaving the fingers free — making it the standard treatment for thumb and wrist injuries ranging from CMC joint arthritis and DeQuervain's tenosynovitis to scaphoid fractures, gamekeeper's thumb (UCL injuries), and post-surgical stabilization.

OrthoTape carries thumb spica splints and braces from the most trusted orthopedic brands — Ossur, Exos (DJO Global), and eLife — ranging from soft, everyday-wear braces to rigid thermoformable fracture splints and complete fiberglass splint kits.

Which Thumb Spica Splint Is Right for You?

Frequently Asked Questions

What conditions require a thumb spica splint?
Thumb spica splints are used for CMC joint arthritis (basal joint arthritis), DeQuervain’s tenosynovitis, scaphoid fractures, gamekeeper’s thumb (UCL tear), skier’s thumb, thumb metacarpal fractures (Bennett’s and Rolando fractures), and post-surgical thumb or wrist immobilization.

What is the difference between a thumb spica splint and a wrist brace?
A standard wrist brace immobilizes the wrist only. A thumb spica splint extends up to include the thumb, immobilizing the first carpometacarpal (CMC) joint and the metacarpophalangeal (MCP) joint of the thumb — which is essential for scaphoid fractures and thumb ligament injuries where wrist-only support is insufficient.

How long should I wear a thumb spica splint?
Wear duration depends on the condition. Scaphoid fractures typically require 8–12 weeks of immobilization. DeQuervain’s and CMC arthritis may require 4–6 weeks of consistent wear. Always follow your physician’s or physical therapist’s guidance on wear schedule.

Can I wear a thumb spica splint while working or doing housework?
Yes — soft thumb spica braces like the Ossur FormFit are specifically designed for activity-based wear during housework, gardening, and light daily tasks. Rigid fracture braces should be worn as directed by your clinician.

Is the Exos thumb spica splint waterproof?
Yes. Exos thermoformable braces are fully waterproof and can be worn in the shower. They are also radiolucent, meaning X-rays can be taken without removing the brace.
