Abstract
An ankle pivot cap for the capture of a dorsiflexion detent pin and a plantar flexion detent pin is disclosed. Each respective pin is captured at its head with the flat pin head exposed to a resilient washer and the pin shank protruding from a restrictive track. Each path has shank capturing turns arrayed in a continuous 'W' shaped path. Each of the shank capturing turns corresponds to a dorsiflexion limiting aperture or a plantar flexion limiting aperture. This correspondence allows shank protrusion with the respective dorsiflexion detent pin and plantar flexion detent pin held in spaced relation to the ankle pivot cap in precise relationship for insertion to corresponding dorsiflexion limiting apertures or plantar flexion limiting apertures on the orthotic. Consequently, adjustment of the orthotic is limited to cap removal, pin setting by movement to a pin capturing turn, followed by reinsertion of the cap to the ankle pivot. An adjustment protocol results allowing either patient or provider to rapidly set and easily adjust the disclosed range of motion appliance.
