What is the Thermoplastic Thumb Spica used for?
It is designed to provide rigid thumb and CMC joint immobilisation where movement needs to be restricted following injury, tendon irritation, ligament damage or surgery.

Can it be used for De Quervain’s tenosynovitis?
It may be used where thumb and wrist immobilisation has been recommended as part of managing De Quervain’s tenosynovitis. Persistent or worsening symptoms should be professionally assessed.

Can the brace be heat moulded?
Yes. The thermoplastic shell can be heat moulded to modify its shape and fit. Significant moulding is best carried out by a trained clinician or orthotic professional.

How should the brace fit?
It should hold the thumb securely without causing excessive pressure, numbness, tingling or skin irritation. The straps should feel firm but not overly tight.

Do I choose Left or Right?
Yes. Select the orientation corresponding to the hand requiring support.

Can I wear it for long periods?
Wear time depends on the reason for immobilisation and any clinical guidance provided. Check the skin regularly and remove the brace if persistent redness, pressure, numbness or irritation develops.

Can I still move my fingers?
The brace is designed primarily to restrict thumb and CMC movement while leaving the remaining fingers available for functional use, although exact movement will depend on fit and individual anatomy.

Is this suitable following thumb surgery?
It may be used post-operatively where rigid thumb immobilisation has been recommended. Follow the fitting and wear schedule provided by the surgical or rehabilitation team.

Does it contain latex?
No. The current product information states that the Thermoplastic Thumb Spica is latex free
