Tuberculosis of the hip.

Tuberculosis of the hip constitutes approximately 15% of all cases of osteoarticular tuberculosis. The common age of presentation is in the second and third decades. In Stages II and III of the disease, the radiologic features are very obvious and diagnostic, and almost always predict the final clinical outcome. A progressive pattern of destruction of the hip occurs in patients who are not treated. Treatment must be instituted early with an aim of salvaging the hip. Treatment comprised of drug therapy, traction, and supervised mobilization produces good results in patients with early stages of the disease. Patients who do not have a favorable clinical response to conservative treatment should have surgery before the hip is destroyed. In the eastern hemisphere, patients prefer a painless but mobile joint, for satisfying the customary needs of squatting, sitting cross-legged, and kneeling. Therefore, excision arthroplasty produces satisfactory results as compared with hip arthrodesis. Total hip arthroplasty should be considered only after a safe period of absolute disease quiescence.
