From: Preserving the first ray or first two rays in forefoot amputation for diabetic foot ulcers
The overall stress levels in the 1 ray amputation (RA) and 1-2 RA groups were markedly higher than those in other groups, with this disparity being particularly pronounced during the terminal stance phase.
