The authors present a case of Charcot joint of the hip joint treated with cementless bipolar hip prosthesis. A 52-year-old man presented with a painless limp. Examination revealed a positive Romberg sign, positive Argyll Robertson pupil, and depression of pallesthesia in his left lower limb. Serum treponema pallidum hemagglutination was positive. Radiograph showed fracture of the femoral neck and typical Charcot joint on his left hip joint. Femoral head prosthetic replacement was carried out without bone cement. During the one-year follow-up, the case did not develop dislocation or loosening of the prosthesis.
