THUMB
WRIST + THUMB

Serious thumb support. Precision where it counts.

What is THUMB?

Get a grip on healing.

THUMB™ is a patent-pending, hand-based thumb spica designed to support and immobilize the thumb’s CMC and MCP joints during rehabilitation and recovery from injury or overuse.

It holds the thumb in a therapeutic position to help reduce pain and inflammation while allowing the wrist and fingers to move freely, enabling functional pinch, comfort, and confident daily use throughout recovery.

What is WRIST + THUMB?

Stability that goes the distance.

WRIST + THUMB™ is a patent-pending, forearm-based (long) thumb spica designed to support and immobilize the thumb and wrist during rehabilitation and recovery when added stability is required.

It provides CMC support with wrist control to help reduce pain and strain, while allowing the fingers to move freely for functional use and confident daily activities.

Why it works.

Digitally designed.
3D printed.
Clinician trusted.

Digitally Designed.
Each THUMB and WRIST + THUMB orthosis is engineered in a digital environment using real-world anthropometric data. The result is precise positioning and consistent support without the guesswork of traditional sizing.

Targeted Joint Control
Support is applied precisely where it’s needed. THUMB stabilizes the CMC and MCP joints. WRIST + THUMB adds wrist control when increased stability is clinically indicated.

Functional Freedom
Stability does not have to mean shutdown. Fingers remain free for pinch, grip, and daily activities while the thumb and wrist are correctly supported.

Comfort that Holds
Low-profile geometry, smooth skin-contact surfaces, and breathable lattice structures reduce pressure points, slipping, and irritation during extended wear.

Built for Real-world Performance
3D-printed construction delivers a consistent fit, rapid availability, and clinic-ready reliability, enabling faster care without compromising outcomes.

Why choose THUMB?

Focused support.
No unnecessary lockdown.

THUMB and WRIST + THUMB are digitally designed thumb spicas that deliver targeted stabilization based on anatomy, not assumptions. Hand-based when motion matters. Forearm-based when added control is required. Both provide reliable thumb support while keeping fingers free for functional use and daily life.

Unlike traditional thumb spicas, mign designs eliminate bulk, guesswork, and hygiene issues—improving comfort, stability, and wear compliance throughout recovery.

How mign’s THUMB & WRIST + THUMB braces compare to legacy splinting:

Feature	Traditional Thumb Spicas	THUMB / WRIST + THUMB
Fit	Generic, inconsistent	Digitally designed, anthropometric
Thumb stabilization	Variable, collapses	Targeted CMC & MCP support
Wrist control	Fixed or overbuilt	Added only when indicated
Bulk	Foam-heavy, rigid	Low-profile, lightweight
Stability	Slips, loosens	Predictably stays put
Functional pinch	Often restricted	Preserved
Comfort	Heat, pressure points	Breathable, smooth contact
Hygiene	Absorbs moisture, odor	Waterproof, easy to clean
Compliance	Frequently removed	Easier to wear, worn longer

Clinical Indications

mign’s THUMB & WRIST + THUMB are indicated for conditions requiring thumb stabilization, with optional wrist control when clinically appropriate, including:

CMC joint osteoarthritis and basal thumb arthritis
MCP ligament injuries, including UCL injuries (Skier’s thumb)
De Quervain’s tenosynovitis
Soft-tissue injuries of the thumb
Post-injury or post-operative thumb stabilization

WRIST + THUMB configuration

Basal thumb (CMC) injuries requiring added wrist control
Acute or post-operative conditions where wrist immobilization improves thumb stability

How to fit THUMB and WRIST + THUMB

Select the size
Use the mign UX Sizing Tool to choose the correct fit for the palm width, secure, not constricting. If the injured hand is swollen or the fit is tight, size up.
Slide it on
The splint should seat comfortably without rotation or pressure at the radial prominence.
Secure the strap
Tighten the strap for locked-in precision. The right fit restricts desired motion, but does not disrupt circulation. Size up if needed.

What to expect

THUMB and WRIST + THUMB are lightweight, low-profile, and designed for daily wear. Patients can use their fingers freely while the thumb, and wrist when indicated, stays comfortably supported, without the bulk, pressure points, or movement common with traditional braces.
