The body includes a distal portion, a proximal portion, and a back joining strap. In the unstressed state, the relative position of the distal and proximal portions maintains the wrist in an extended state. The joining strap is deformable such that when pressure is exerted downward on the palm support, the joining strap is deformed to enable the pivotal movement of the distal portion with respect to the proximal portion about a transverse articulation axis parallel to the flexion-extension axis of the wrist. When pressure is released, the body returns to the unstressed state due to resilience. The distal portion is arranged to pivot with respect to the proximal portion about the articulation axis while assisting the extensor muscles of the wrist. ## Claims ### Claim at position 1 1-11. (canceled) ### Claim 12 An orthosis for treating muscle disorders of the elbow, the orthosis including a body comprising: a distal portion arranged to be placed at the level of the hand, and including a substantially transverse palm support for the palm of the hand, and extending in the proximal direction by two substantially longitudinal lateral branches joined at their proximal end by a substantially transverse distal bridge arranged to be placed over the posterior side of the wrist; a proximal portion arranged to be placed at the level of the forearm and including two substantially longitudinal lateral wings arranged to bear on either side of the forearm and which are joined at their distal end by a substantially transverse proximal bridge arranged to be placed over the posterior side of the forearm; a back joining strap extending substantially longitudinally and connecting the distal and proximal bridges; a strap associated with each of the lateral wings of the proximal portion to hold the lateral wings tight against each other, and passing underneath the anterior side of the forearm, the body of the orthosis having a geometry such that the relative position of the distal and proximal portions, in the non-stressed state, corresponds to holding in extension of the wrist when the orthosis is worn; wherein the joining strap is elastically deformable so that when pressure is applied to the palm support opposite the joining strap, the joining strap becomes deformed to allow pivoting of the distal portion relative to the proximal portion about an articulation axis which is substantially transverse and parallel to the flexion-extension axis of the wrist when the orthosis is worn; wherein when said pressure is released, the body returns to the non-stressed state via elasticity by pivoting of the distal portion relative to the proximal portion about said articulation axis; wherein the body is made in a single piece in semi-rigid material. ### Claim 13 (depends on 12) The orthosis according to claim 12, wherein said orthosis is free of any member bearing on the dorsal side of the hand such as a strap or equivalent. ### Claim 14 (depends on 12) The orthosis according to claim 12, wherein the bridge comprises a notch arranged on its distal edge and located in the region of the ulnar styloid when the orthosis is worn. ### Claim 15 (depends on 12) The orthosis according to claim 12, wherein said orthosis further comprises a cushion attached underneath the dorsal or posterior part of the body of the orthosis, underneath at least part of the distal bridge and of the joining strap, the cushion is arranged to be inserted between the user's wrist and the body of the orthosis. ### Claim 16 (depends on 15) The orthosis according to claim 15, wherein the cushion comprises at least one raised portion extending substantially transversely and facing the hand when the orthosis is worn. ### Claim 17 (depends on 12) The orthosis according to claim 12, wherein said orthosis further comprises rigidifying means arranged to prevent deformation of the body of the orthosis when pressure is applied to the palm support opposite the joining strap. ### Claim 18 (depends on 17) The orthosis according to claim 17, wherein the rigidifying means comprises a rigid part fastened onto the joining strap removable to prevent elastic deformation of the joining strap. ### Claim 19 (depends on 18) The orthosis according to claim 18, wherein the rigidifying means comprises at least one rigid member mounted on the proximal portion, respectively on the distal portion of the body of the orthosis, to pivot about a substantially transverse axis between an active position in which the member is fastened onto the distal portion, respectively onto the proximal portion, by retaining means, to prevent deformation of the body of the orthosis, and an inactive position in which the member allows deformation of the body of the orthosis. ### Claim 20 (depends on 19) The orthosis according to claim 19, wherein the member comprises a lateral tab having a first end which is mounted on a lateral wing of the proximal portion, respectively a lateral branch of the distal portion, of the body of the orthosis, and a second end which is provided with removable retaining means on said lateral branch and said lateral wing, in active or inactive position. ### Claim 21 (depends on 12) The orthosis according to claim 12, wherein the body is transparent or translucent. ### Claim 22 (depends on 12) The orthosis according to claim 12, wherein said orthosis further comprises an elbow support in the form of a fabric sleeve, the body of the orthosis being placed over the elbow support when the orthosis is worn.
