[Radiological assessment of the hip after Mittelmeier and Parhofer- Mönch stem implantation].
Radiological assessment and results after cementless stems implantation at Mittelmeier (Autophor 900 and 900S) and Parhofer-Mönch total hip replacement are presented. Engh criteria were used to assess implantation of the stem on a-p radiograph. Vertical migration, presence of ossifications around the tip of the stem within medullar cavity and radiolucency in 7 Gruen zones were evaluated. The investigation revealed that vertical migration, presence of ossifications around the tip of the stem within medullar cavity and radiolucency around the stem were more frequent after implantation of stems with no microporous surface and Autophor 900 type stems. Radiolucency appeared mainly within IV and VII Gruen zone.
