A multicentric study permitted us to report 94 cases of non-tuberculous infections of the hip joint in the adult (13.4% of the cases of septic arthritis observed over the same period). A local predisposing factor (37.2%) and/or general predisposing factors (22.6%) were frequently noted. The routine search for bacteria permits identification of the latter in 71.3% of cases; the germ was usually a staphylococcus, arthritis due to Gram negative bacilli were found in 12% of the cases. The authors emphasize the interest of daily joint aspiration and traction on the lower limb associated with bactericidal antibiotic therapy which are the only means able, in their view, to improve the poor functional prognosis in these cases of hip joint infections.
