Embodiment Construction

[0031] Figure 1A , 1B and 1C show the carpus metacarpal joints of the thumb and index finger. The carpus metacarpal joint MSA of the thumb includes the joint between the metacarpal MP and the trapezium TZ and the joint between the navicular SC and the trapezium TZ and trapezium TD. The carpus metacarpal joint of the index finger includes the joint between the metacarpal MI of the index finger and the trapezium TD, and the joint between the trapezium TD and the navicular SC. Orthotics can affect one and / or the other joint MSA, in Figure 1A and 1B identified by shading. The thumb can also be affected by subluxation of the metacarpal MP relative to the trapezoid TZ, as in Figure 1C shown.

[0032] Figure 2-4 and 6 show a thumb orthosis according to one embodiment, the purpose of which is to bring relief to persons suffering from carpometacarpal arthrosis or thumb metacarpal subluxation. figure 2 and 6 The orthotic is shown placed on the hand. image 3 and 4 A portio...

Abstract

The invention concerns a hand orthosis for supporting the thumb, the orthosis comprising a main part (1) comprising: a first portion (2) in the form of a sleeve fitted to a portion of the thumb extending to the fold area between the thumb and the palm of the hand, a second portion (4) assembled by a seam line in the form of a sleeve fitted to the wrist, a third portion (3) linking the first and second portions, shaped so as to envelop an area of the hand extending along the thumb metacarpal between the back of the hand and the palm, and comprising an opening to allow the palm of the hand to pass therethrough, the main part being shaped so as not to cover the fold area between the thumb and the palm of the hand and being made from an elastic material having a Young's modulus of between 0.5Mpa and 1Mpa in a direction corresponding to a longitudinal axis of the first portion.

Description

technical field [0001] The present invention relates to a thumb orthosis (orthosis). The aim of the present invention is in particular to provide relief to persons suffering from arthrosis of the wrist. Background technique [0002] Many people experience wrist arthrosis as they age, especially at the joint between the thumb and wrist. The condition, known as "wrist arthrosis," disproportionately affects women and manifests itself as sudden, severe pain. At night, random movements of the thumb can cause pain to the point of preventing sleep. The disorder may involve the joint between the metacarpal and trapezium of the thumb and / or the scaphoid and the joint between the trapezium and trapezium. The disease can also cause instability or subluxation of the joint between the metacarpal and trapezium of the thumb. [0003] Wrist arthrosis is generally treated with medication and / or orthotic accessories. Some of these attachments take the form of rigid orthotics to completel...
