Journal ArticleDOI
Hip contact forces and gait patterns from routine activities.
Georg Bergmann,Georg Deuretzbacher,Markus O. Heller,Friedmar Graichen,Antonius Rohlmann,J Strauss,Georg N. Duda +6 more
TL;DR: The paper focuses on the loading of the femoral implant component but complete data are additionally stored on an associated compact disc that contains complete gait and hip contact force data as well as calculated muscle activities during walking and stair climbing and the frequencies of daily activities observed in hip patients.
Journal ArticleDOI
Hip joint loading during walking and running, measured in two patients
TL;DR: In one hip in the first patient and in the second patient the direction of large forces approximated the average anteversion of the natural femur, so the joint loading was observed over the first 30 and 18 months, respectively, following implantation.
Journal ArticleDOI
Loading of the knee joint during activities of daily living measured in vivo in five subjects.
Ines Kutzner,B. Heinlein,B. Heinlein,Friedmar Graichen,Alwina Bender,Antonius Rohlmann,Andreas M. Halder,Alexander Beier,Georg Bergmann +8 more
TL;DR: In general, resultant contact forces during dynamic activities were lower than the ones predicted by many mathematical models, but lay in a similar range as measured in vivo by others.
Journal ArticleDOI
Musculo-skeletal loading conditions at the hip during walking and stair climbing.
Markus O. Heller,Georg Bergmann,G. Deuretzbacher,Lutz Dürselen,M. Pohl,Lutz Claes,Norbert Haas,Georg N. Duda +7 more
TL;DR: The presented approach is considered as a useful means to determine valid conditions for the analysis of prosthesis loading, bone modeling or remodeling processes around implants and fracture stability following internal fixation.
Journal ArticleDOI
Standardized Loads Acting in Hip Implants
TL;DR: Proposals for the most demanding activities, the time courses of the contact forces and the required cycle numbers for testing are given here and it was shown that friction only very slightly influences the stresses in the implant neck and shaft.
