RESUMO
Osteoarticular tuberculosis is a rare complication of the disseminated disease and appears, in different series, between 10% to 20%, trough hematogenous spread. Tuberculosis hip involvement is less than 10% of all the cases of osteoarticular tuberculosis. The diagnosis is confirmed by the detection of Mycobacterium tuberculosis in samples obtained from joint fluid or synovial membrane biopsy by direct examination and culture, in order to perform antimicrobial susceptibility testing. Here, we present a patient infected with the human immunodeficiency virus (HIV) who developed a disseminated tuberculosis with affection of the hip in the context of the immunodeficiency related with the retrovirus.
La tuberculosis osteo-articular es una localización infrecuente de las formas diseminadas de la enfermedad tuberculosa. Su incidencia, según las distintas series, oscila entre 10% y el 20%. Su patogenia es la diseminación por vía hematógena. La coxitis o afección tuberculosa de la cadera representa menos de 10% de las TB osteo-articulares. El diagnóstico se confirma con la detección de Mycobacterium tuberculosis en las muestras obtenidas del líquido articular o la biopsia de la membrana sinovial a través del examen directo y el cultivo. Presentamos un paciente con infección por el virus de la inmunodeficiencia humana (VIH) que desarrolló una TB diseminada con compromiso de la cadera en el contexto de su inmunodeficiencia.

RESUMO
PURPOSE: To confirm the effect of the frog leg lateral radiographs for determining the clinical indication of total hip arthroplasty for high riding dislocation and to discuss its theoretical background. MATERIALS AND METHODS: A consequent series of reconstructive THA were studied in 28 recent tuberculous hips. Twenty-three hips (17patients) with developmental dysplastic hip were compared. Preoperatively, frog-leg lateral radiographs were performed in all the patients, which were enhanced using a 2-dimensional computer model to predict the reattachment of the greater trochanter. RESULTS: The modified scores of Merle d'aubigne and Postel improved from a mean of 2.6 points preoperatively to a mean of 5.1 points. Sciatic nerve palsies occurred in three cases. In two cases, they fully recovered, but in one case, it did not. We confirmed that old high dislocation of the hip could be adopted in type 1 and 2 categories of frog leg lateral position. The reconstruction of hip was relatively simple in type 3, however, further study is necessary in type 5 due to unsuitable abduction contracture. CONCLUSION: We confirm that frog leg lateral radiography is effective for determining the operative indication of high riding dislocation. However irreducible frog leg lateral position is absolutely contraindirated for total hip arthroplasty.
