Movable core guide wire: evaluation of improved model.

Six commercially available movable core guide wires were compared with each other and with a new design in glass models simulating tortuous vessels. The results demonstrate a wide variability in performance of the commercially available wires and the superiority of the new design.

[Tuberculous infection of total hip prosthesis: report on two cases (author's transl)].

M. tuberculosis infection of a total hip prosthesis was observed in two patients. Clinical and bacteriological diagnostic features are described, as well as the two possible physiopathological mechanisms involved: activation of a chronic local lesion or blood dissemination.

[Study of factors favoring infection in total hip prosthesis. Twenty-five observations].

The authors report 25 cases of infection following total hip replacement and individual factors are analysed. The role of immunological abnormalities is discussed. They distinguish early infection due to the operative conditions from late infection where individual factors are the most important.
