Total Hip Arthroplasty in an old man with Acetabular Protrusion due to Active Tuberculosis Infection: A Case Report

After tuberculosis of the spine, hip tuberculosis is the most common site that can be infected with extrapulmonary TB. In the early stages, patients are referred with complaints of pain around the hip, and after a while, they might experience deformities, shortening, and limited movements. Because hip tuberculosis mimics the symptoms of other hip diseases like rheumatoid arthritis, and osteoarthritis, diagnosis is difficult. Based on the clinical features of hip tuberculosis, four stages are known for this condition: synovitis, early arthritis, advanced arthritis, and advanced arthritis with subluxation/dislocation. Here, we aimed to report a rare case of hip tuberculosis secondary to pulmonary tuberculosis and the result of the total hip arthroplasty. Our patient was in advanced arthritis with a subluxation/dislocation stage and an acetabular protrusion that caused restriction of movements.
