title: Hydroxyapatite-coated total hip replacement in Paget's disease: 20 patients followed for 4-8 years.
abstract: 20 patients, who had had total hip replacements for symptomatic osteoarthrosis secondary to Paget's disease, were followed for a mean of 6 (4-8) years. Proximal hydroxyapatite-coated stems were implanted in all patients. 12 patients received hydroxyapatite-coated, 2 cemented (Muller type) and 6 cementless cups (Morsher type). The mean Harris hip score was 31 (7-40) points preoperatively and 88 (74-100) postoperatively. The radiographic evaluation revealed good stability and fixation using Engh's criteria. One stem subsided early more than 5 mm and then seemed to stabilize. Our findings support the use of hydroxyapatite total hip implants for patients with this disease and osteoarthrosis.
