[Use of an isolator (so-called "bubble") in orthopaedic surgery (author's transl)].

The results of 2 series of casualties presenting with femoral neck fractures and operated with Moore prostheses are compared. The first was operated between September 18, 1972 and July 17, 1975 in a conventional way; the other between July 18, 1975 and January 10, 1977 under an Isolator. The rate of infection was much reduced in the latter. It seems to indicate the important function of this apparatus in the prevention of postoperative infection.
