Total Hip Replacement for the Ankylosed Hip

Ankylosis of the hip restricts patient's activities of daily life and causes pain in the contralateral hip, lower back and knees. We performed 4 total hip replacements in 3 patients who received malpositioned arthrodeses for osteoarthritis (27-year-old and 56-year-old women) and tuberculosis (54-year-old man), and in a patient of malpositioned spontaneous ankylosis for tuberculosis (64-year-old man). At an average follow-up period of 5.7 years, all of them showed improved activities of daily life and relief of their preoperative pain in the associated joints with good muscle power about the hips.
