[Bacillary trochanteritis. Apropos of 30 cases].

Tuberculous trochanteritis is rare. The authors report 30 cases, 2/3 of which were seen in sanatoria. They occurred in four cases out of five in patients with long standing tuberculosis but were sometimes the presenting feature. Development of an abscess of the trochanteric serous bursa is a virtually constant complication. Their minimal functional consequences and slow progression endow them with an apparently benign nature which masks the risk of secondary complications (4 cases of coxalgia). Radiological appearances, minimal in early forms, are currently becoming more abundant by virtue of new medical imaging techniques. Specific antibiotic therapy is adequate in two cases out of three, completed in advanced and aggressive forms by local procedures dominated by surgical excision (13 cases).
