Abstract: An improved mechanical joint construction for pivotally interconnecting two members, particularly members of an orthopedic or orthotic body appliance, to limit the degree of pivotal movement between the members and adjustably control the position of limited pivotal movement of the two members; comprising first securement components for attachment to a first appliance member to be interconnected and presenting a generally flat planar surface with pivot pin extending outwardly from the surface and a protrusion on the surface spaced radially from the pivot pin; second securement components for rigid attachment to a second appliance member to be interconnected and comprising an inner peripherally serrated plate with central opening for receipt of the pivot pin to support the inner plate for rotation thereon, an arcuate slot in the inner plate spaced radially from the opening therein and receiving the protrusion for movement between ends of the slot to limit relative rotational movement of the inner plate on the p

Abstract: A low profile neck ring for attachment to supporting structure of an orthopedic body brace employed to treat curvature of the spine comprising a resiliently deformable unitary collar plate for closely surrounding the lower neck portion of a wearer, the plate having an anterior yoke portion for overlying the sternum of the wearer and unitarily interconnecting a pair of elongate web portions having a lateral width substantially greater than the thickness of the plate, the web portions initially extending upwardly and rearwardly of the yoke portion to overlie the clavicle areas on either side of the neck of the wearer and having further posterior web portions extending downwardly and terminating in abutting relation to overlie the area of the spine adjacent the scapula of the wearer.
