Abstract

A unitary flexible body having an anchor portion wrapping about the wrist to secure the body there, the anchor portion freely offset from the thumb, palm and dorsum of the hand, the body having a support extension extending distally from the anchor portion in supporting relation with the Thenar Emminence of the palm, and extending part way about the thumb via the web space between the thumb and forefinger, and having terminal attachment to said anchor portion.

Claims

1. A CMC support, comprising

a) a unitary flexible support body having an anchor portion wrapping about the wrist to secure the body thereto, the anchor portion freely offset from the thumb, palm and dorsum of the hand,

b) the body having a support extension extending distally from the anchor portion in supporting relation with the Thenar Emminence of the palm, and extending part way about the thumb via the web space between the thumb and forefinger, and having terminal attachment to said anchor portion,

c) the support body in extended and flattened condition having flat generally T-shaped flap configuration, the T-shape defining a laterally extending cross-piece and a stem which tapers away from the central region of the cross-piece and a terminal in alignment with the stem, the stem and terminal extending longitudinally away from the cross-piece, the stem having laterally opposite edges which diverge toward the cross-piece and which merge arcuately with diverging edges of the cross-piece.

2. The support of claim 1 wherein said edges of the cross-piece defining define two like concave edge regions at said opposed edges of the support extension.

3. The support of claim 2 wherein said opposed edges of the support extension are defined by seam binding structure.

4. The support of claim 2 wherein a flat, substantially non-stretchable reinforcement liner extends adjacent a flat side of the support extension to engage said web portion of the user'"'"'s hand.

5. The support of claim 1 including hook and loop material on the body to secure said anchor portion, and to secure the extension strap terminal to the anchor portion.

6. The support of claim 1 wherein

i) the body is stretchable

or ii) or the body is non-stretchable.

14. The method which includes

i) providing the CMC support of claim 1, and

ii) attaching said CMC support to the hand to create a pinch effect between the support extension at said web space, and said anchor portion.

7. A CMC support, comprising

a) a brace configured for wrapping application of an anchor portion to the wrist of the user,

b) the brace including a support extension extensible over the web between the user'"'"'s thumb and forefinger and so as to bear against the CMC joint portion of the user'"'"'s hand,

c) the support extension having a distal portion releasably attachable to said anchor portion of the brace, and so as to exert web lifting force to the strap, while leaving the thumb free to flex,

d) the brace in extended and flattened condition having flat generally T-shaped flap configuration, the T-shape defining a laterally extending cross-piece and a stem which tapers away from the central region of the cross-piece and a terminal in alignment with the stem, the stem and terminal extending longitudinally away from the cross-piece, the stem having laterally opposite edges which diverge toward the cross-piece and which merge arcuately with diverging edges of the cross-piece.

8. The support of claim 7 wherein said edges of the cross-piece define two concave edge regions at said opposed edges of the support extension.

9. The support of claim 8 wherein said opposed edges of the support extension are defined by seam binding structure.

10. The support of claim 8 including a flat, substantially non-stretchable reinforcement liner extending adjacent a flat side of the support extension to engage said web portion of the user'"'"'s hand.

11. The support of claim 7 wherein the support extension has connection to said anchor portion to extend adjacent the palm of the hand.

12. The method of providing for hand CMC support, which includes:

a) providing a unitary flexible support body having an anchor portion wrapping about the wrist to secure the body thereto, the anchor portion freely offset from the thumb, palm and dorsum of the hand,

b) the body provided to have a support extension extending distally from the anchor portion in supporting relation with the Thenar Emminence of the palm, and extending part way about the thumb via the web space between the thumb and forefinger, and having terminal attachment to said anchor portion,

c) the support body provided to have in extended and flattened condition a flat generally T-shaped flap configuration, the T-shape defining a laterally extending cross-piece, and a stem which tapers away from the central region of the cross-piece, and a terminal in alignment with the stem, the stem and terminal extending longitudinally away from the cross-piece, the stem having laterally opposite edges which diverge toward the cross-piece and which merge arcuately with diverging edges of the cross-piece.

13. The method of claim 12 including exerting lifting pressure on a hand region of said body that is defined by a web region of said extension.

15. The method which includes

i) providing a flexible brace anchor portion and a support extension from said anchor portion

ii) and attaching said brace anchor portion to the wrist and said support extension over the web region between the thumb and forefinger with tension, thereby to create a pinch effect acting to create brace pressure exertion against the CMC joint region of the hand,

iii) said anchor portion and extension provided to have in extended and flattened condition a flat generally T-shaped flap configuration, the T-shape defining a laterally extending cross-piece and a stem which tapers away from the central region of the cross-piece and a terminal in alignment with the stem, the stem and terminal extending longitudinally away from the cross-piece, the stem having laterally opposite edges which diverge toward the cross-piece and which merge arcuately with diverging edges of the cross-piece.
