This has a metal barscrewed to its under surface, with a ring for attachment of theextension cord {Fig. 25). This metal bar stands out for one inchon each side and rests upon the side-bars of the splint, runningupon these with very little friction, but serving to prevent thefoot from rotating inwards or Fig. 25.—Authors wire cradle Leg splint. It is made of r« .steel wire, bent at 110 at the knee. The thigh part is 12 and 10 in. wide, the leg piece is 26 in. long, and the lowerend is 5 in. from the supporting board.
