title: Quadrilateral shaped brims made from high-density polyethylene for long leg calipers.
abstract: Quadrilateral shaped brims made of high-density polyethylene have been used with satisfactory results on more than 120 patients who needed ischial-bearing long leg calipers. At first the fitting technique was the same as that used for thigh amputees. Subsequently it has been possible to fit most patients from a range of pre-formed brims. The properties of high-density polyethylene allow the caliper side irons to be riveted directly to the brim which, with the use of ready-made brims, allows a patient to be fitted rapidly with a comfortable and effective caliper.
