Orthopedic hinge assembly for a leg brace
First Claim
1. An orthopedic hinge assembly for interconnecting an upper and a lower portion of a brace, comprising:
- a housing member;
means on the housing member for enabling attachment to a brace portion;
an abductor member movably mounted on the housing member;
means on the abductor member for enabling attachment to another brace portion;
a first adjuster member movably mounted to the housing member;
a second adjuster member movably mounted to the housing member, wherein the abductor member, first adjuster member, and second adjuster member are pivotally mounted about a common pivot point;
a stop member extending through the respective first and second adjuster members; and
means for removably fastening the first and second adjuster members together to define a fixed relative movement of the abductor member including a fastener member journalled in the housing member for radial movement relative to the common pivot point, whereby an operator can move the first and second adjuster members relative to each other to a desired position to define the limits of movement of the abductor member and then fasten the first and second adjuster members together so that the adjuster members are fixedly attached together.

Abstract
An orthopedic hinge assembly for connecting an upper and lower portion of a brace, such as a knee brace, includes a hinge housing member with an abductor member movably mounted on the housing member. A pair of adjuster members are also mounted to the housing member and a stop member attached to the abductor member extends through arcuate apertures on the adjuster members. The adjuster members can have outer indentations and manually operable fastener assembly can fix or release the respective adjuster members so that they can be set to a desired position to define the limits of movement of the abductor member and thereby control flexion and extension of the patient'"'"'s leg.

20. An orthopedic hinge assembly for interconnecting an upper and a lower portion of a brace, comprising;
-
a housing member formed of a pair of thin metal plates; means on the housing member for enabling attachment to a brace portion; a flat plate abductor member movably mounted on the housing member; means on the abductor member for enabling attachment to another brace portion; a first flat metal plate adjuster member movably mounted to the housing member for rotation about an axis of rotation, the first plate adjuster member having a first aperture radially offset from the axis of rotation; a second metal flat plate adjuster member movably mounted to the housing member for rotation about the axis of rotation, the second plate adjuster member having a second aperture radially offset from the axis of rotation and at least partially overlapping the first aperture; a stop member extending through the respective first and second plate adjuster members; and means for removably fastening the first and second plate adjuster members together to define a fixed relative movement of the abductor member whereby an operator can move the first and second adjuster members relative to each other to a desired position to define the limits of movement of the abductor member by adjusting the amount of overlap of the respective first and second apertures to limit the movement of the stop member, and then fasten the first and second plate adjuster members together so that the adjuster members are fixedly attached together. - View Dependent Claims (21, 22)
