ABSTRACT:
An arrangement for adjusting the heel height of a prosthetic foot includes a cavity at the rear aspect of the prosthetic foot adapted to receive a separate locking block therein. Both the locking block and the cavity, as seen inside elevational view, are arcuate in configuration. Secured to the lower aspect of the block are a pair of arcuate rails spaced transversely from each other. Secured to the upper surface of the cavity and in complementary relation to the arcuate rails are a pair of transversely spaced grooves or tracks to receive the respective rails. The locking block may be moved longitudinally and arcuately of the prosthetic foot to thereby adjust the heel height of the foot when it is secured to a prosthetic device. A locking bolt is used to accomplish the attachment of the foot to the device and hold the block in fixed position to maintain the desired heel height.
