Περίληψη:
We evaluated the effect of the inclination angle, position, and containment of 53 cementless cups inserted in patients with congenital hip disease (CHD), after a minimum of 10 years of follow-up. The polyethylene wear rate was significantly greater when the cup was placed in more than 45° inclination (P = .045) or if the cup was placed lateral to the teardrop position by more than 25 mm (P = .001). Aseptic loosening of the femoral component was significantly greater when the cup was placed more than 25 mm superiorly to the teardrop (P = .049). Cup placement of more than 25 mm lateral to the teardrop affected significantly periacetabular osteolysis (P = .032). In CHD cases, it is preferable to avoid excessive vertical inclination, lateral, and superior placement of cementless cups in an attempt to obtain better containment. © 2010 Elsevier Inc.
