Abstract

A spiral brace has an inner surface that corresponds to a digital representation of an injured limb. The spiral brace can wrap around a length of the limb in a helical manner. The body of the spiral brace may be a single piece structure that is fenestrated to provide air circulation to the injured limb.

Claims (27)

1. A custom brace designed to be virtually fitted on a limb of a patient to be braced prior to fabrication for supporting the limb of the patient comprising:

a brace body having a spiral shape that is adapted to wrap more than one full turn around the limb of the patient, wherein a proximal portion of the brace body is adapted to fit around a forearm portion of the limb, a distal portion of the brace body is adapted to fit around a hand portion of the limb and a thumb section on the distal portion, the thumb section having a thumb hole, the thumb section adapted to surround a thumb of the patient; and

an inner surface of the brace body that corresponds to a digital representation of the limb of the patient to be braced;

wherein the brace body has a length axis, the brace body is fabricated in the spiral shape and the brace body in the spiral shape has a plurality of fused planar layers that are parallel to the length axis.

2. The custom brace of claim 1 wherein the distal portion of the brace body has a palmar section that is adapted to support a palm of the hand portion and a dorsal section that is adapted to fit over a dorsum of the hand portion.

3. The custom brace of claim 2 wherein the inner surface of the brace body at the palmar section of the distal portion includes a convex surface.

4. The custom brace of claim 1 wherein each of the fused planar layers of the brace body is made of a homogeneous plastic material that is the same for each of the fused planar layers.

5. The custom brace of claim 1 wherein the distal portion of the brace body is adapted to surround a thumb portion of the limb.

6. The custom brace of claim 1 wherein a width of the brace body at the proximal portion is greater than 0.5 inch and less than 2 inches.

7. The custom brace of claim 1 wherein a thickness of the spiral shape of the brace body is greater than 0.05 inch and less than 0.50 inch.

8. The custom brace of claim 1 wherein a pitch of the spiral shape is greater than 2 inches and less than 6 inches.

9. The custom brace of claim 1 wherein the spiral shape of the brace body defines a center axis and the plurality of fused planar layers are approximately parallel to the center axis.

10. The custom brace of claim 1 wherein the brace body has a single piece spiral configuration.

11. A custom brace designed to be virtually fitted on a limb of a patient to be braced prior to fabrication for supporting an arm of a patient, the arm having fingers, a thumb, a hand, a wrist and a forearm, the custom brace comprising:

a brace body having a spiral configuration that is adapted to wrap more than one full turn around the arm of the patient to at least partially immobilize the arm of the patient, wherein a proximal portion of the brace body is adapted to fit around the forearm of the arm, a distal portion of the brace body is adapted to fit around the hand of the arm and a thumb section on the distal portion, the thumb section having a thumb hole, the thumb section adapted to surround the thumb of the arm; and

an inner surface of the brace body that corresponds to a digital representation of the arm of the patient to be braced;

wherein the brace body has a length axis and the brace body in the spiral configuration has a plurality of fused planar layers that are parallel to the length axis.

12. The custom brace of claim 11 further comprising:

a distal limb support at a distal end of the brace, the distal limb support is adapted to at least partially surround the hand and not restrict movement of fingers.

13. The custom brace of claim 12 wherein an edge of the distal limb support is adapted to be positioned adjacent to a palmar digital crease of the hand.

14. The custom brace of claim 12 wherein an edge of the distal limb support is adapted to not extend over proximal phalanx segments of the fingers.

15. The custom brace of claim 12 wherein an edge of the distal limb support is adapted to not extend over a thenar portion of the hand allowing a thumb of the hand to move freely.

16. The custom brace of claim 12 wherein the inner surface of the brace body at the distal limb support has a convex surface that is adapted to be adjacent to a palmar surface of the hand.

17. The custom brace of claim 12 wherein the custom brace is adapted to prevent palmar flexion movement of the hand.

18. The custom brace of claim 12 wherein the custom brace is adapted to allow rotational movement of the hand about a center axis of the custom brace relative to the forearm.

19. The custom brace of claim 11 wherein the brace body includes a distal limb support that is adapted to be adjacent to a palmar surface of the hand, a middle section that is adapted to be adjacent to a posterior surface of the wrist and a proximal limb support at a proximal end of the custom brace, the proximal limb support that is adapted to be adjacent to an anterior surface of the forearm.

20. The custom brace of claim 11 wherein the brace body has a single piece spiral configuration.
