Abstract
A device for tensioning a surgical appliance is disclosed. The device comprises two elongate lever elements, anchor means articulated to a first end portion of one of the lever elements and adapted to be attached by a cortical screw to a bone fragment on one side of a fracture, and a hook element provided on a first end portion of the respective other lever element and adapted to be engaged with a plate member attached to a bone fragment on the respective other side of the fracture. The other end portions of the two lever elements are articulatedly intercoupled by means to exert a force between the two lever elements and to indicate the magnitude of that force. A threaded member is rotatably retained in each of two guide elements to interconnect intermediate portions of the two lever elements. The guide elements are pivotably supported on respective ones of the two lever elements and the threaded member is rotatably adjustable to enable a surgeon to vary the spacing between the respective first end portions of the two lever elements. Preferably, the hook element is pivotable between two alternative positions, in a first of which it is supported to exert traction on the plate member…
