De Quervain orthosis for night-time use
The Chrisofix® night-time De Quervain orthosis supports immobilisation of the thumb MCP and CMC joints. This PREMIUM FORTE model includes lining and an adjustable, pre-shaped shell for night-time splinting as part of the treatment plan.
Product overview
Night-time use; right hand REF 64, left hand REF 65; three sizes: S, M and L. Sizing is based on palm width.
Why this design?
Adjustable fit
The pre-shaped shell can be adapted with gentle pressure. Initial fitting and substantial reshaping should be performed by a healthcare professional.
Targeted support
The orthosis supports the thumb MCP and CMC joints. The wearing schedule follows the individual treatment plan.
PREMIUM FORTE with lining
This model combines a malleable shell, lining and fastening straps. Fitting does not require heat or water.
Indications
A treating healthcare professional may select this night-time orthosis as part of care for the following applications:
- Night-time splinting for De Quervain syndrome.
- Immobilisation of the thumb metacarpal or CMC joint after injuries and sprains.
- Rehabilitation after fractures and supplementary immobilisation following surgery for thumb metacarpal fractures, including Bennett, Rolando and Winterstein fractures.
How it works
By supporting the MCP and CMC joints, the orthosis limits movements that are undesirable within the treatment plan. The malleable shell allows fitting adjustments, while the straps hold the orthosis on the hand.
Fitting and use
Fit: adapt the pre-shaped orthosis to the hand with gentle pressure. Substantial reshaping is a healthcare professional’s task.
Fasten: adjust the thumb section and straps to provide support without excessive tightness.
Check: monitor the fit and skin during use. Keep repeated bending of the shell to the necessary minimum.

Frequently asked questions
How long should I wear it?
“Night-time use” describes the intended application, not a fixed wearing schedule for every patient. Follow the schedule determined by your treating healthcare professional.
Can I use the same size for the daytime model?
Not automatically. The two models use different measurements. Check the size chart and fit of each model separately.
Can the orthosis be washed?
Yes, at 30 °C, followed by air drying. It is intended for repeated use by one patient.
What is De Quervain syndrome?
De Quervain syndrome affects tendons on the thumb side of the wrist. Pain may increase when moving the thumb, gripping or lifting. Similar symptoms can have other causes; product selection should follow professional assessment.
