[Clinical experience of an offloading orthosis to prevent and heal diabetic foot ulcers of the digits].

Rev Med Suisse 2021 Feb;17(725):315-319

Institut de santé globale, Faculté de médecine, Université de Genève, 9 chemin des Mines, 1202 Genève.

Globally, every 30 seconds a lower limb amputation is carried out due to diabetes, in 85 % of cases preceded by a foot ulcer. One of the main causes of foot ulcer formation is abnormal mechanical pressure and shear, the alleviation of which is therefore a key element in the management of diabetic foot ulcers. The toes, often neglected in routine clinical examinations, are particularly vulnerable because of the thin soft tissue between the bones and the skin and because of trauma due to ill-fitting shoes.
