Abstract
An orthosis including a proximal portion consisting of an armband and a strap around the forearm as well as a distal portion consisting of a palm support and a strap around the hand. The support is pivotable relative to the armband about a transverse pivot axis which substantially coincides with the flexion/extension axis of the user's wrist joint when the orthosis is being worn by a user. The orthosis further comprises pivotal locking means for use in a desired angular position.
Claims13
A wrist orthosis, intended to treat carpal tunnel syndrome, comprising:
- a proximal portion designed to grip a forearm;
- a distal portion designed to grip a hand;
- pivot means of the proximal and distal portions in relation to each other, around a transverse pivot axis that, when the wrist orthosis is worn by a user, is essentially combined with the flexion/extension axis of the user's wrist joint;
- a connection for locking the pivot means in a desired angular position (Θ);
- wherein the proximal portion includes an essentially rigid armband designed to extend only against a rear face of the forearm and a flexible strap connected to the armband and designed to pass against a front face of the forearm, such that the forearm is gripped between the armband and the strap;
- and the distal portion includes an essentially rigid support designed to extend only under a palm of the hand and a flexible strap connected to the support and designed to pass against the back of the hand, such that the hand is gripped between the support and the strap.

- pivot means of the proximal and distal portions in relation to each other, around a transverse pivot axis that, when the wrist orthosis is worn by a user, is essentially combined with the flexion/extension axis of the user's wrist joint;
- a nut for adjusting and tightening the proximal portion relative to the distal portion, and lateral walls of the proximal portion having a lug for measuring a desired angular position (Θ);
- wherein the proximal portion includes an essentially rigid armband designed to be placed against a rear face of the forearm and a flexible strap connected to the armband and designed to pass against a front face of the forearm, such that the forearm is gripped between the armband and the strap;
- and the distal portion includes an essentially rigid support designed to be placed under a palm of the hand and a flexible strap connected to the support and designed to pass against the back of the hand, such that the hand is gripped between the support and the strap.

- wherein the armband includes a main portion in cradle form, which, when the orthosis is worn by a user, covers the forearm, said main portion comprising a central portion placed against the rear face of the forearm and two lateral portions arranged on either side of the forearm, two distal lateral portions extending essentially longitudinally in the distal direction, each from a lateral portion of the main portion, on either side of the forearm, the pivot axis being situated essentially at the distal end portion of distal lateral pads.
