1. A brace for supporting an anatomical joint about which a first anatomical member rotates relative to a second anatomical member, the anatomical joint having an outwardly projecting bone on the lateral or medial side of the joint, the brace comprising:

  • a first support member for orthopedically supporting the first anatomical member adjacent the anatomical joint;

    a second support member for orthopedically supporting the second anatomical member on an opposite side of the anatomical joint;

    the first and second support members having confronting faces overlying one another adjacent the joint;

    a large substantially circular first opening in the confronting face of the first member; and

    circular hinge means having a tubular extension affixed to the confronting face of the second support member and extending laterally through the first opening in the first support member, the tubular extension having a large second opening through it aligned with the first opening, the tubular extension having an annular outer lip overlapping an outer face of the first support member around said first opening for rotatably interconnecting the confronting faces of the first and second support members for causing free relative rotation of the support members about a transverse axis through the first and second openings while joining the support members in a side-by-side relation substantially limiting relative lateral motion and relative longitudinal motion of the support members;

    the first and second openings being sufficiently large to allow the bone projecting from the side of the anatomical joint to project into said openings to avoid pressure contact between the projecting portion of the bone and the orthopedically supportive interconnected faces of the first and second support members when the brace is worn so that said support members provide orthopedic support for the anatomical joint.
