ABSTRACT:
A positive casting for a human foot for use in making a foot orthosis is disclosed. The positive casting includes a main section, a rear section, and a front section. The rear section is movable with respect to the main section for correcting deformities in the rearfoot. The front section is movable with respect to the main section for correcting deformities in the forefoot. A mechanism is also provided for fixing together and adjustably positioning the three sections thus formed with respect to one another. The casting can include a first ray section cut from the front section and movable with respect to the front section for correcting deformities in the forefoot and first ray. A method is also disclosed for forming a foot orthosis which includes the improvement of sectioning a positive casting made of a foot into a main section, a front section, and a rear section. The main section, front section, and rear section are adjusted with respect to each other to correct for deformities in the foot. The relative positions of the main section, front section, and rear section are then fixed with respect to one another. An orthosis is then made by pressing or forming a formable material such as thermoplastic over the adjusted positive casting.
