[Tuberculous osteoarthritis of the foot and ankle joint]

The authors have reviewed 26 cases of tuberculosis of the foot and 32 of the ankle, which they have treated personally. All the patients were adults and most presented with advanced destruction of bone and joints. Bacterial and histological confirmation of the diagnosis was obtained in 56 patients. All were treated by chemotherapy; the drugs and regime varied over the years. All responded well to this treatment, but one relapsed after 24 months. Orthopaedic problems were usually managed by immobilisation in plaster casts, but 6 patients required arthrodesis, 5 of the ankle and one triple fusion. The functional results of the standard treatment were generally good. Arthrodesis is seldom needed and should be performed only for permanent pain or crippling deformity.
