Hip dislocation revealing hip tuberculosis. A case report.

Hip dislocation is an uncommon presentation of hip tuberculosis. We report a case in an 18-year-old woman with active hip tuberculosis. An attempt to reduce the dislocation 7 weeks into antituberculous therapy was followed by necrosis of the femoral head. Although severe forms of hip tuberculosis are common in endemic areas, dislocation is exceedingly rare. Capsule laxity and/or synovial hypertrophy probably contribute more to the occurrence of dislocation than does the accumulation of pus.
