Abstract

A method of making functional orthotics from a multiplicity of uniquely designed injection molds which have been constructed by studying large numbers of replicas produced from uncorrected replicas that replicate the contour of the feet of a multiplicity of patients. In one form of the method of the invention, following a careful dimensional study of the corrected replicas, they are grouped into families, the members of which exhibit lower surface contours that are substantially identical. An injection mold is then made for each of the identified families, in a manner such that the mold will produce an orthotic having an upper surface that corresponds to the lower surface of the corrected orthotic that makes up the group. Companion data is then developed which correlates the corrected replicas of each identified family with the uncorrected replicas from which they were made. A study of the uncorrected replicas then provides data as to the contour of the patient's feet which they replicate. This data can then be compared with new patient data provided by the prescribing doctor and the mold can be selected which will produce an injection molded orthotic which is appropriate for the particular patient.
