Title:
FRACTURE FIXATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2005069752
Kind Code:
A3
Abstract:
A fracture fixation system in which a plate is secured to stable bone and posts are inserted at varying angles into an unstable bone fragment by engaging in rotatable bearings which are fixedly secured in the plate when the posts are fully engaged in the bone fragment. The bearings are formed as truncated spherical members having a number of longitudinal slots extending partway along the length of the bearing to form petals which are expanded outwardly when the posts are advanced in the bearing to produce non-uniform distribution of forces between the bearing and the plate which generate force couples to resist angulation of the posts and loss of fracture fixation. Various other ways of producing non-uniform force distribution are described.
