Abstract

A thumb orthosis, particular for correcting malpositions of the thumb in the carpometacarpal joint, includes a) a substantially dimensionally stable molded body bent in a U-shape, which is fitted on the hand between the thumb and index finger in the applied state and supports the thumb and fixes it at a distance from the index finger, wherein the molded body bent in a U-shape has a first end portion and a second end portion, and b) a strap which is fastened by one strap end to the first end portion of the molded body, wherein the second end portion of the molded body has a guiding element for guiding the strap, for example has a turning element for turning the strap back.

First claim

The invention claimed is:

1 . A thumb orthosis comprising:
a) a substantially dimensionally stable molded body bent in a U-shape, which in the applied state is fitable on a hand between a thumb of the hand and an index finger of the hand and supports the thumb and is operative to fix the thumb at a distance from the index finger, wherein the molded body bent in a U-shape has a first end portion and a second end portion; and b) a strap fastened by one strap end to the first end portion of the molded body, the second end portion of the molded body comprising a guiding element for guiding the strap, the strap, as viewed from the first end portion in the applied state, guidable once around the wrist such that it overlaps itself at an overlap point, wherein two mutually overlapping strap portions are not rigidly connected to one another at the overlap point, and the strap is guided on the guiding element of the second end portion, and the end of the strap is reversibly fastenable to the strap.

2 . The thumb orthosis according to claim 1 , wherein the second end portion of the molded body has a turning element as the guiding element for turning the strap, wherein, as viewed from the first end portion, in the applied state, the strap is guided once around the wrist such that it intersects with itself at an intersection point as an overlap point defining two intersecting strap portions, wherein the two intersecting strap portions are not rigidly connected to one another at the intersection point, and the strap is turned at the turning element of the second end portion.

3 . The thumb orthosis (according to claim 2 , wherein the turning element on the second end portion of the molded body is formed as a notch in the second end portion.

4 . The thumb orthosis according to claim 1 , wherein the guiding element is formed as a loop for pulling the strap through.

5 . The thumb orthosis according to claim 1 , wherein the guiding element is reversibly fastenable to the strap via a pin closure, via a hook and loop fastener, or via a hook/eye closure.

6 . The thumb orthosis according to claim 1 , wherein the guiding element comprises a perforated strap and fixing element.

7 . The thumb orthosis according to claim 2 , wherein the overlap point is located in a defined overlap region.

8 . The thumb orthosis according to claim 7 , wherein the defined overlap region is formed as a loop on or in the strap, through which the strap is pulled, wherein the loop is arranged in the region of the strap which follows the first end portion of the molded body.

9 . The thumb orthosis according to claim 8 , wherein the loop forms a slot that is wider than the width of the strap.

10 . The thumb orthosis according to claim 7 , wherein the defined overlap region is designed as a hook-and-loop fastener.

11 . The thumb orthosis according to claim 1 , wherein the end of the strap is reversibly fastened to the strap via a pin closure, via a hook-and-loop fastener, or via a hook/eye closure.

12 . The thumb orthosis according to claim 1 , wherein the molded body and the strap are integrally formed.

13 . The thumb orthosis according to claim 1 , wherein the molded body is saddle-shaped and has air holes, and wherein the molded body consists of a shapeable material.

14 . The thumb orthosis according to claim 1 , wherein the thumb orthosis is operable to pull the thumb into a plane of a palm of the hand when worn on the hand.

15 . A thumb orthosis comprising:
a substantially dimensionally stable moulded body bent in a U-shape, which in the applied state is fitable on a hand between a thumb of the hand and an index finger of the hand and supports the thumb and is operative to fix the thumb at a distance from an index finger; wherein the moulded body bent in a U-shape has a first end portion and a second end portion, and a strap fastened by one strap end to the first end portion of the moulded body; the second end portion of the moulded body comprising a guiding element for guiding the strap; the strap, as viewed from the first end portion in the applied state, being guideable once around the wrist such that it intersects with itself at an intersection point to form two non-parallel portions of the strap; and wherein the strap is guided on the guiding element of the second end portion, and the end of the strap is reversibly fastenable to the strap, and wherein the guiding element is formed as a perforated strap and fixing element.
