Amputation of the greater toe causes loss in biomechanical function of foot during the gait, such as propulsion and balance. They use various combinations of medial and lateral struts with either anterior or posterior shells. The surgeon attempts to fully retain the metatarsal bone in any case.

This would dorsiflex the residual foot to some degree, restoring anatomical position and providing a lift to rebalance the malleoli.
