Abstract
An elastic orthopedic device for protecting, for example, the knee joint, has metallic inserts which are articulated for full forward and rearward motion yet which resist lateral forces applied to the joint and tendencies of the joint to dislocate in a lateral direction.
Claims6
A compact protective orthopedic device for joints of the body, said device comprising:
- tubular elastic support means, said support means being adapted to substantially surround one of said joints, said support means having formed axially and peripherally therein sleeve means;
- and brace means being shaped and dimensioned to be insertingly accommodated by said sleeve means and said brace means being characterized as fully articulated in the normal direction of articulation of said joint, said brace means being further characterized as being rigid in a direction transverse to said normal direction, said bracing means including more than two link members, each said link member being greater longitudinally than laterally and being pivotally articulated to its adjacent partners for flexing in a common plane and each said brace means having more than one pivot for permitting said link members to pivotally articulate with respect to one another and with said joint.
A compact protective orthopedic device for a joint of the body, said device comprising:
- generally tubular elastic support means, said support means having formed axially peripherally therein sleeve means;
- and brace means, said brace means including more than two articulated link members, said link members having axially elongated links and a plurality of pivots therebetween and being adapted to articulate in a single common plane while rigidly resisting forces transverse to said plane, said brace means shaped and dimensioned to be insertingly accommodated by said sleeve means, said brace means being oriented to articulate in the normal direction of articulation of said joint, whereby forces exerted transverse to said normal direction are rigidly resisted by said brace means.
A compact protective orthopedic device for joints of the body, said device comprising:
- a tubular elastic support means, said support means being attached to substantially surround one of said joints having formed axially and peripherally therein sleeve means, brace means being shaped and dimensioned to be insertingly accommodated by said sleeve means and characterized as fully articulated in the normal direction of articulation of the body joint, said brace means being further characterized as being rigid in a direction transverse to said normal direction and including five link members, each said link member being substantially thinner than long and being pivotally articulated to and overlapping its immediate adjacent link member for flexing in a common plane, and said links are proportioned in ratios of 1.5:1.1:1:1.1:1.25.
