TOTAL HIP ARTHROPLASTY AND PAGET’S BONE DISEASE

Purpose: Hip joint involvement is a frequent complication of Paget’s disease. We conducted a multicentric retrospective study to analyse perioperative problems and outcome after total hip arthroplasty in patients with Paget’s disease.Material and methods: Thirty-nine total hip arthroplasties were implanted between 1979 and 1998 in 35 patients with Paget’s disease of the hip (four bilateral cases). The series included 20 men and 15 women, mean age 74 years (55–86). The pre and postoperative status was evaluated with the Harris score and radiographically. We recorded operative time, blood loss, and events noted in the operative report. Among the 35 patients, 24 were retained for analysis (three deaths, eight lost to follow-up) at mean 62 months.Results: The mean preoperative Harris score was 46/100 (18–67). Eighteen patients had leg length discrepancy. Nine had permanent hip flexion associated with external rotation and seven had coxa vara. Twenty-nine patients were given anti-osteoclastic treatment preoper...
