ABSTRACT:
The functional forefoot orthotic of this invention comprises a shell plate that is conformed to the sole of the foot replica, a forefoot posting shim is applied to the upper surface of the shell plate. A stabilizing heel platform may also be applied to the bottom of the shell plate. The forefoot posting shim is applied at the level of the first to third metatarsals for a varum prescription. The shape, size and thickness of the posting shim is determined by the prescription. The forefoot posting shim will have a width that will be determined by the degree of deformity in the patient's forefoot. It will be wide enough to support at least the first metatarsal and may be wide enough to support two or all three of the first-to-third metatarsals. The forefoot posting shim will accommodate the patient's varum forefoot deformity so as to provide, in combination with the shell plate replica of the patient's foot, a stable forefoot platform for the patient's foot.
