[Decubitus ulcer].

Bedsores are caused by prolonged pressure of soft tissues. Prevention is now better established. Better adapted mattresses should be used systematically. High fever and denutrition should be especially watched. Correct medical treatment has to provide faster cicatrisation if the pressure sore unfortunately occurs. Surgical treatment by muscular flaps has now really good results but costs a lot more in management of occasional or chronic bedridden patients.
