Abstract

A hinge for an orthopedic device includes a first part having a first end with a gear component, and a second part hingedly attached to the first part. The second part defines a cavity at a first end, and a worm is located within the cavity and engages the gear component. An adjustment element is adapted to regulate the worm relative to the gear component for articulating the first part relative to the second part.

First claim

1 . A hinge for an orthopedic device, comprising:
a first part having a first end with a gear component; a second part hingedly attached to the first part, the second part defining a cavity at a first end; a worm located within the cavity and engaging the gear component; an adjustment element adapted to regulate the worm relative to the gear component for articulating the first part relative to the second part.

2 . The hinge of claim 1 , further comprising a cylinder extending transversely through the first part and the second part at the first ends thereof.

3 . The hinge of claim 1 , wherein the second part defines first and second arms enclosing sides of the first end of the first part.

4 . The hinge of claim 3 , wherein the first part defines first and second notches for accommodating the first and second arms of the second part.

5 . The hinge of claim 1 , wherein the worm is secured to the adjustment element such that rotation of the adjustment element causes the worm to rotate within the cavity.

6 . The hinge of claim 5 , wherein the worm and the adjustment element are coaxially arranged.

7 . The hinge of claim 5 , wherein the adjustment element has a head with a traction feature for enabling rotation of the adjustment element.

8 . The hinge of claim 1 , wherein the first part includes indicia indicating the degree of adduction or abduction the first part is arranged relative to the second part.

9 . The hinge of claim 1 , wherein the gear component extends only partially about the first end of the first part.

10 . The hinge of claim 1 , wherein the first and second parts define first and second flanges, respectively, for securing to first and second sections of an orthopedic device.

11 . An orthopedic device, comprising:
a first strut; a second strut; a hinge having first and second parts securing to the first and second struts, respectively, the hinge including: the first part having a first end with a gear component; the second part hingedly attached to the first part, the second part defining a cavity at a first end; a worm located within the cavity and engaging the gear component; an adjustment element adapted to regulate the worm relative to the gear component for articulating the first part relative to the second part.

12 . The orthopedic device of claim 11 , wherein the first and second parts define first and second flanges, respectively, for securing to first and second struts.

13 . The orthopedic device of claim 11 , wherein the worm is secured to the adjustment element such that rotation of the adjustment element causes the worm to rotate within the cavity.

14 . The hinge of claim 11 , wherein the worm and the adjustment element are coaxially arranged.

15 . The hinge of claim 11 , wherein the first part includes indicia indicating the degree of adduction or abduction the first part is arranged relative to the second part.

16 . The hinge of claim 11 , wherein the gear component extends only partially about the first end of the first part.

17 . The hinge of claim 11 , wherein the first and second parts are arranged for adjusting the first and second struts in adduction and abduction.

18 . A method for adjusting a hinge in an orthopedic device having first and second struts connected by the hinge having first and second parts hingedly connected to one another and engaging one another by a gear component carried by the first part and a worm carried by the second part, the method comprising;
adjusting an angle of the first part relative to the second part by turning the worm gear such that the first part articulates relative to the second part.

19 . The method of claim 18 , further comprising the step of providing indicia on the hinge and checking the indicia to determine an adduction or abduction angle of the first part relative to the second part.

20 . The method of claim 18 , further comprising the step of turning an adjustment element connected to the worm for rotating the worm and causing the first part to articulate relative to the second part.
