摘要

In total hip arthroplasty, a straight stem seems to provide better results than an anatomic one. A new generation of anatomic stems is under evaluation, so the follow-up is still short and cannot compare with studies of straight stems. The clinical and radiographic results of 176 patients who underwent 189 primary total hip arthroplasties using an anatomic, collared, proximally hydroxyapatite (HA)-coated femoral component were prospectively determined from 1 to 6 years follow-up. The stem is ribbed in the metaphyseal region, allowing to decrease the elasticity modulus, to augment the surface for bone ingrowth and to preserve the space needed for the circulation of the inner half side of the corticalis. The average postoperative Harris hip score was 96.7 points. All femoral components had radiographic evidence of bone ingrowth fixation at the final follow-up. There were no cases of loosening for any reason. The strength of the study is limited by the short follow-up, but our preliminary excellent clinical results with stable bone ingrowth fixation allow us to continue to use this stem following patients over time.
