Integrated Study of the Distal Femur Biphasic Plate: Exploring In Vivo, In Vitro, and In Silico Methodologies

Annchristin Andres, Kerstin Wickert, Michael Roland, Marcel Orth et autres

PURPOSE: An emerging concept for plate fixation of fractured bones in humans changed from absolute stability through relative stability to a new concept of a predefined range of elastic movement with mechanical amplitude limitation ("Biphasic Plate," 41 medical, Bettlach, Switzerland). As this …

Predicting the effect of individual weight-bearing on tibial load and fracture healing after tibial plateau fractures–introduction of a biomechanical simulation model

Annchristin Andres, Michael Roland, Kerstin Wickert, Stefan Diebels et autres

Purpose: The prescribed amount of weight-bearing after tibial plateau fractures is controversial because it affects osteosynthetic construct stability and fracture healing. We aim to introduce a simulation model that adequately predicts the effects of different weight-bearing amounts on stability and healing, based …

Concepts and clinical aspects of active implants for the treatment of bone fractures

Bergita Ganse, Marcel Orth, Michael Roland, Stefan Diebels et autres

Nonunion is a complication of long bone fractures that leads to disability, morbidity and high costs. Early detection is difficult and treatment through external stimulation and revision surgery is often a lengthy process. Therefore, alternative diagnostic and therapeutic options are currently being …
