  • Patent number: 5782783
    Abstract: An orthosis for the upper body is provided for controlling the shoulder and the arm. The orthosis employs a connection between the waist band and the upper part of the orthosis, specifically a lateral upright, which has two linked joints. Preferably, the lower joint is attached centrally to the waist band and is a spherical zone joint which accommodates bending at the waist and variation in the shape of the torso. The second joint is a pivot joint which accommodates rotation about an axis parallel to the long axis of the lateral upright upon the lower end of which, preferably, it is mounted.

  • Patent number: 5038765
    Abstract: A true bipivotal hinge for orthopaedic use having a hinge body and a pair of hinge arms with adjacent end portions pivotally connected to the side walls of the body for independent pivotal movement of each arm. A T-shaped insert element is removably secured within the hinge body and has a pair of stop portions with abutment surfaces engagable with the end portions of the arms for limiting the degree of extension of such arms. In a system for accommodating such a hinge to a patient's needs, a plurality of insert elements are provided, each being of substantially the same size and shape but having distinctive angularity of their abutment surfaces so that by interchanging one insert element for another, the hinge may be adjusted to provide the required degree of maximum arm extension.

  • Patent number: 5039247
    Abstract: An orthopedic and orthotic hinge having a hinge body that includes two spaced, parallel plates with two hinge arm carriers having end portions pivotally mounted between the plates for movement in directions of flexion and extension. The end portions of the hinge arm carriers have peripheral teeth that respectively engage two toothed slide members. Such members are slidably disposed between the plates, preferably carried in grooves formed therein, and are independently movable with respect to each other when the hinge arm carriers are pivoted. First and second variable stops are provided by the hinge for limiting the extent of sliding movement in opposite directions of the two slide members, thereby restricting extension and flexion of the hinge arm carriers while at the same time permitting true bi-pivotal operation of the hinge. In one embodiment, the variable stops are offset from the midplane of the hinge body and the toothed slide members have extensions engageable with such stops.

  • Patent number: 5000170
    Abstract: An orthopedic and orthotic bipivotal hinge assembly having a hinge body and a pair of coplanar and independently-pivotal hinge arms. The proximal end portions of the hinge arms are disposed within the hinge body and have at least one set of interdigitating end plates defining an arrangement of abutment surfaces that are coplanar with each other, face generally in the same direction, and are disposed in side-by-side relation, when the arms are in first positions of adjustment (e.g., extension). In one embodiment, a single set of interdigitating plates with one such arrangement of abutment surfaces is provided; in a second embodiment two sets of interdigitating plates with two arrangements of abutment surfaces for controlling both extension and flexion are provided. Continuously variable extension and/or flexion control is achieved by an adjusting screw, or a pair of adjusting screws, carried by the hinge body.
