Orthopedic thumb splint and method for stabilizing the trapeziometacarpal joint of a user

1. An orthopedic thumb splint adapted for stabilizing a carpometacarpal joint of a user, said orthopedic thumb splint comprising:

a flexible fabric splint body comprising a wrist portion and a generally funnel-shaped thumb portion, said generally funnel-shaped thumb portion defining a narrowed opening for receiving a thumb of the user;

a detachable and relocatable stay pod adapted for custom placement on said flexible fabric splint body at a base of said generally funnel-shaped thumb portion; and

a thumb-abducting flexible X-strap secured to said flexible fabric splint body adjacent the narrowed opening of said generally funnel-shaped thumb portion, and comprising first and second diverging distal ends having respective inside surfaces, the inside surface of each of said first and second diverging distal ends comprising touch fasteners designed to releasably mate at respective first and second points of releasable attachment with complementary touch fasteners located on an outside surface of said flexible fabric splint body, whereby an adjustable abduction force is capable of being applied to the thumb of the user by pulling said X-strap outwardly from said generally funnel-shaped thumb portion and downwardly towards said wrist portion of said flexible fabric splint body, and then mating the touch fasteners of said first and second diverging distal ends and flexible fabric splint body to releasably attach said first and second diverging distal ends at a base of the thumb, such that said X-strap extends over said stay pod at the base of said generally funnel-shaped thumb portion.

2. The orthopedic thumb splint according to claim 1 , wherein said wrist portion of said flexible fabric splint body comprises first and second cooperating flexible closure straps having respective free ends adapted to releasably wrap around a wrist of the user.

3. The orthopedic thumb splint according to claim 2 , wherein said flexible fabric splint body comprises an inverted T-shaped non-stretch region located between said first and second closure straps, and extending upwardly along said generally funnel-shaped thumb portion towards the narrowed opening.

4. The orthopedic thumb splint according to claim 3 , wherein said flexible fabric splint body is substantially stretchable in adjacent areas outside of said non-stretch region.

5. The orthopedic thumb splint according to claim 4 , wherein said flexible fabric splint body comprises added padding in said non-stretch region.

6. The orthopedic thumb splint according to claim 2 , wherein the free ends of said first and second closure straps comprise respective touch fasteners.

7. The orthopedic thumb splint according to claim 6 , wherein said first closure strap comprises an intermediate inside patch of pre-hold touch fasteners spaced apart from its free end, and adapted to form a preliminary holding point when wrapping said first and second closure straps together around the wrist of the user.

8. The orthopedic thumb splint according to claim 7 , wherein the free end of said first closure strap comprises a hook fastener tab.

9. The orthopedic thumb splint according to claim 1 , wherein said X-strap further comprises a proximal looped end extending around said generally funnel-shaped thumb portion adjacent the narrowed opening.

10. The orthopedic thumb splint according to claim 9 , wherein said X-strap is permanently affixed to said flexible fabric splint body on a web side of said generally funnel-shaped thumb portion.

11. The orthopedic thumb splint according to claim 10 , wherein said X-strap further comprises an intermediate inside touch fastener located between said touch fasteners of said first and second diverging distal ends, and said intermediate inside touch fastener providing a third point of releasable attachment of said X-strap, wherein said first, second and third points of releasable attachment are spaced apart and separated from one another along a portion of said X-strap.

12. The orthopedic thumb splint according to claim 1 , wherein said stay pod comprises a semi-rigid metal stay sandwiched between opposing outside and inside fabric layers.

13. The orthopedic thumb splint according to claim 12 , wherein said stay pod comprises touch fasteners on said inside fabric layer adapted to releasably mate with complementary touch fasteners of said splint body.

14. The orthopedic thumb splint according to claim 1 , wherein said first and second diverging distal ends of said X-strap comprise respective hook fastener tabs.
