A hinge-brace for a fracture cast is described. The hinge-brace comprises a hinge portion having secured to at least one end thereof a head-plate for incorporation in a fracture cast. The head has a thickened central region and the hinge brace has upper and lower surfaces which are intended to lie within the cast and are substantially planar, whereby, when the head-plate is embedded in casting material, the formation of dead spaces in the region where the hinge portion joins the head-plate is substantially eliminated. The hinge portion may be a monocentric or polycentric hinge portion and may be of metal or plastics, and the head-plates may be roughened or formed with teeth, splines or prongs to enhance and promote mechanical capture of the casting material.
