Résumé
One hundred twenty two hidroxyapatite-coated acetabular implants, 45 threaded and 77 fixed with screws, were reviewed. The average follow-up period was 3.8 years. The results have been very encouraging, obtaining 93% of excellent and good results with threaded cups and 83 % when fixed with screws. Threaded cups had better scores for avascular necrosis (p<0.01) and primary osteoarthrosis (p<0.05). The worse results were achieved for patients with revisions and inflamatory diseases. No evidence of loosening was found. The placement of threaded cups was more horizontal. Male sex was associated with developing of heterotopic ossification. There were 7% of dislocations associated with a longes distance from the teardrop and as shorter length of the calcar from the lesser trochanter.
