Abstract: Apparatus and techniques for arresting or correcting lower leg, ankle and foot deformities which readily adapt themselves to progressive application of corrective forces to the deformed body portion. A brace is composed of a plurality of articulated portions with fasteners joining the articulated portions. Certain fasteners are periodically released, brace portions relatively moved to new locations and the fasteners relocked to apply renewed corrective bending moments or torques to portions of the anatomy.

Abstract: An orthopedic brace for spinal applications is formed from a plurality of relatively rigid hollowed-out parallelepiped portions adjacent pairs of which are joined along a relatively thin web of flexible material common to the two portions to provide pivotal motion between the two adjacent portions. Relative pivotal movement between the two adjacent 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 nut engages a resilient washer to provide a limited yielding between the portions. The number of such portions joined together is arbitrary.

Abstract: 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.
