Abstract

A brace for a carpometacarpal joint of a thumb includes a body made of an elastomeric material. The body includes a wrist strap configured to surround a wrist, a dorsal projection extending from the wrist strap, a first palmar strap extending between a proximal end connected to the wrist strap and a distal end configured to removably attach to the dorsal projection, and a second palmar strap extending between a proximal end connected to the wrist strap and a distal end configured to removably attach to the dorsal projection. The brace also includes a heat-moldable insert positioned within the body. The heat-moldable insert is configured so as to be positioned over a CMC joint of the thumb.

First claim

What is claimed is:

1. A brace for a carpometacarpal joint of a thumb, comprising:
a body made of an elastomeric material, the body including
a wrist strap configured to surround a wrist,
a dorsal projection extending from the wrist strap, the dorsal projection configured to extend across a portion of a dorsum of a hand,
a first palmar strap extending between a proximal end connected to the wrist strap and a distal end, the first palmar strap configured to extend across a portion of a palm of the hand and over a purlicue of the hand, the distal end configured to removably attach to the dorsal projection, and
a second palmar strap extending between a proximal end connected to the wrist strap and a distal end, the second palmar strap configured to extend across a portion of the palm of the hand and over the purlicue of the hand, the distal end configured to removably attach to the dorsal projection; and

an insert positioned within the body, the insert comprising a heat-moldable material that is pliable above a temperature and substantially stiff below the temperature, the insert positioned within the body so as to be positioned over a carpometacarpal joint of a thumb.

2. The brace of claim 1 , wherein the elastomeric material comprises silicone.

3. The brace of claim 1 , wherein the elastomeric material comprises a thermoplastic elastomer.

4. The brace of claim 1 , wherein the temperature is between approximately 130° F. and approximately 250° F.

5. The brace of claim 1 , wherein the second palmar strap is connected to the wrist strap between a connection of the first palmar strap to the wrist strap and the dorsal projection.

6. The brace of claim 5 , wherein the first palmar strap and the second palmar strap extend from the wrist strap to a length that is longer that a length that the dorsal projection extends from the wrist strap.

7. The brace of claim 6 , wherein a distal end of the first palmar strap extends from the wrist strap farther than a distal end of the second palmer palmar strap extends from the wrist strap.

8. The brace of claim 5 , wherein the first palmar strap is separated from the second palmar strap by a gap that is smaller than a gap separating the second palmar strap and the dorsal projection.

9. A brace for a carpometacarpal joint of a thumb of a hand, comprising:
a body including
a wrist strap;
a dorsal projection extending from the wrist strap;
a first palmar strap extending between a proximal end connected to the wrist strap and a distal end, the first palmar strap configured to extend across a portion of a palm of the hand and over a purlicue of the hand, the distal end configured to removably attach to the dorsal projection, and
a second palmar strap extending between a proximal end connected to the wrist strap and a distal end, the second palmar strap configured to extend across a portion of the palm of the hand and over the purlicue of the hand, the distal end configured to removably attach to the dorsal projection.

10. The brace of claim 9 , wherein the body comprises an elastomeric material.

11. The brace of claim 10 , wherein the elastomeric material comprises silicone.

12. The brace of claim 10 , wherein the elastomeric material comprises a thermoplastic elastomer.

13. The brace of claim 9 , further comprising an insert embedded within the body so as to be positioned over a CMC joint of the thumb when the brace is worn.

14. The brace of claim 13 , wherein the insert comprises a stiff material.

15. The brace of claim 13 , wherein the insert comprises a heat-moldable material that is pliable above a temperature and stiff below the temperature.

16. The brace of claim 15 , wherein the temperature is between approximately 130° F. and approximately 250° F.

17. The brace of any of claim 9 , wherein the wrist strap is configured in size and shape to encircle a patient's wrist when the brace is worn.

18. The brace of any of claim 9 , wherein the first and second palmar straps are each configured in size and shape to extend across a portion of the palm of the hand and over the purlicue of the hand.

19. The brace of any of claim 9 , wherein the dorsal projection is configured in size and shape to extend across a portion of a dorsum of the hand.

20. A brace for a carpometacarpal joint of a thumb, comprising:
a body including
a wrist strap configured to encircle a patient's wrist when the brace is worn, and
a first palmar strap connected on a first end to a first location of the wrist strap and connected on a second end to a second location of the wrist strap, the strap configured in size and shape to extend across a portion of the patient's palm, over a purlicue, and across a portion of a dorsum of the patient's hand, and
a second palmar strap connected on a first end to a first location of the wrist strap and connected on a second end to a second location of the wrist strap, the strap configured in size and shape to extend across a portion of the patient's palm, over the purlicue, and across a portion of the dorsum of the patient's hand; and

an insert embedded within the body, the insert comprising a heat-moldable material that is pliable above a temperature and stiff below the temperature.
