1. A wrist support, comprising: (a) a first section configured to receive a forearm, (b) a second section configured to receiver a hand, and (c) a bridging section extending between and connecting together said first section and said second section, (d) wherein said bridging section is integrally formed in a molding step with at least a portion of one of said first section and said second section, and (e) wherein said bridging section permits flexing of said second section relative to said first section in a radial-ulnar plane.
2. The wrist support of claim 1, wherein said bridging section includes an intermediate portion having a height in the volar-dorsal plane that is greater than its width in the radial-ulnar plane.
3. The wrist support of claim 1, wherein said bridging section and at least a portion of said second section are integrally formed in a molding step, and wherein said first section is formed in a different molding step.
4. The wrist support of claim 1, wherein said bridging section and at least a portion of said second section are integrally formed in a molding step from a first elastomeric material, and wherein said first section is formed in a different molding step from a different material.
5. The wrist support of claim 1, wherein said bridging section further includes at least one strap attachment opening for receipt there through of a strap.
6. The wrist support of claim 1, wherein said first section and said second section each includes at least one strap attachment opening for receipt there through of a strap.
7. The wrist support of claim 1, further comprising a tensioning line that extends between said first section and said second section for applying tension between said first section and said second section.
8. The wrist support of claim 7, wherein said first section further includes a rotary device for shortening of a portion of said tensioning line extending between said first section and said second section for increasing the tension therebetween.
9. The wrist support of claim 7, wherein said tensioning line extends along an extent of said bridging section for spanning a wrist.
10. The wrist support of claim 9, further comprising a guide channel defined by the bridging section for receiving and guiding said tensioning line between said first section and said second section.
11. The wrist support of claim 9, further comprising a tension line guide disposed on said bridging section for guidance of said tensioning line between said first section and said second section.
12. The wrist support of claim 11, wherein said tension line guide comprises at least one grommet through which said tensioning line passes in extending between said first section and said second section.
13. The wrist support of claim 11, wherein said tension line guide comprises a hub and multiple arms depending from said hub.
14. The wrist support of claim 7, wherein said first section defines a first axis for receiving a forearm along said first axis, wherein said second section defines a second axis for receiving a hand along said second axis, whereby an angle is defined between the first axis and the second axis, and wherein tension applied by the tensioning line maintains said angle.
15. The wrist support of claim 14, further comprising a rotary device from which extends the tensioning line, said rotary device operable to adjust the length of the tensioning line thereby adjusting said angle.
16. The wrist support of claim 15, wherein the rotary device includes a control knob, and wherein rotation of the control knob in a first rotational direction shortens the tensioning line for adjusting said angle.
17. A wrist support, comprising: (a) a first section for receiving a forearm along a first axis defined by said first section; (b) a second section for receiving a hand along a second axis defined by said second section; (c) a bridging section extending between and connecting together said first section and said second section; and (d) an adjustment system including a device and a line depending from said device, said line extending between said first section and said second section and extending along said bridging section, said device operable to adjust the length of said line thereby adjusting said second section and second axis thereof relative to said first section and said first axis thereof.
18. The wrist support of claim 17, wherein said bridging section is integrally formed in a molding step with at least a portion of one of said first section and said section, said bridging section permitting flexing of said second section relative to said first section in a radial-ulnar plane.
19. The wrist support of claim 17, wherein said device includes a rotatable control knob, and wherein rotation of said control knob in a first rotational direction causes drawing of a portion of said line into said device.
20. A wrist support, comprising: (a) a forearm component for receiving a forearm; (b) a hand component for receiving a hand; (c) a hinge extending between and connecting together said forearm component and said hand component, said hinge including an intermediate elastomeric portion having a height in a volar-dorsal plane that is greater than its width in a radial-ulnar plane; (d) a tensioning line further connecting said forearm component and said hand component; and (e) a tensioning line adjustment mechanism for selectively controlling the length and the tension of the tensioning line; (f) wherein shortening said tensioning line by said tensioning line adjustment mechanism draws said hand component in a dorsal direction relative to said forearm component.
