Abstract: A weight-bearing stance corrected foot orthotic (12) is adapted to be used on the foot (2) of a anaesthetised patient in the supine or prone position, the weight bearing stance corrected foot orthotic (12) adapted to dorsiflex the toes of the forefoot of the patient an angle of between 30° to 50° to the plane of the foot (2). A surgical foot orthotic (12) is formed by the steps of disposing a patient's foot (2) or both feet in a weight bearing neutral position and dorsiflexing the forefoot or forefeet of the patient such that patient's foot (2) or feet are in or towards the Windlass configuration. A first orthotic (5) correcting the stance of the patient in the weight bearing position with dorsiflexed forefoot is formed and this is scanned to form an electronic image of the corrective load bearing surface.
