Acetabular component deformation with press-fit fixation.
Acetabular component deformation secondary to forces encountered during insertion is a potential consequence of the press-fit technique. This study characterized the stiffness of Pinnacle 100 cups (DePuy, Warsaw, Ind) via mechanical testing and used this information with intraoperative measurements of cup deformation to calculate the in vivo forces acting on cups inserted during hip arthroplast...

متن کاملA cementless, elastic press-fit socket with and without screws
BACKGROUND The acetabular component has remained the weakest link in hip arthroplasty regarding achievement of long-term survival. Primary fixation is a prerequisite for long-term performance. For this reason, we investigated the stability of a unique cementless titanium-coated elastic monoblock socket and the influence of supplementary screw fixation. PATIENT AND METHODS During 2006-2008, we...
متن کاملThe tapered press fit total hip arthroplasty: a European alternative.
The tapered rectangular press fit femoral component design of Karl Zweymüller remains highly successful since its inception in 1979. The longitudinal taper and rectangular cross-section provide unequaled primary stability, which promotes consistent secondary osseointegration to the grit-blasted titanium surface, even in osteoporotic bone. The "fit without fill" concept provides for bone conserv...
متن کاملStiffness and Eigenfrequencies of Press-Fit Acetabular Shell Designs
INTRODUCTION: Squeaking of hard-on-hard hip joint bearings has recently become a concern in modern total hip arthroplasty due to its high impact on the quality of life of the patient [1]. Many factors such as malpositioning of implant play a role in the arisal of this phenomenon [2]. The probability of the excitation of audible vibrations is also related to prosthesis design [3]. In particular ...
