An orthopedic brace is formed from at least two relatively rigid hollowed-out parallelepiped portions joined along a relatively thin web of flexible material common to the two portions to provide pivotal motion between the two portions. Relative pivotal movement between the two portions is selectively restricted by an elongated threaded rod which is pivotably affixed at one end to one of the parallelepiped portions and extends through a portion of the other parallelepiped portion with a nut threadedly engaging the rod for adjustment therealong to selectively pull the other parallelepiped portion angularly toward the one parallelepiped portion. The number of such portions joined together is somewhat arbitrary. In the preferred knee brace form, there are four parallelepiped portions each joined to another to form a pair by a relatively thin web and each pair having a threaded rod and nut for selectively restricting pivotal movement between the portions of the pair. The pairs are similarly joined to a hinge arrangement allowing normal knee motion. The normal knee motion may be restricted if desired.
