Abstract:
Objective To design and manufacture an external fixator for close reduction of fibu la and tibial fractures.Methods The all-ring reduction and fixation system made of duroplasts comprises three main parts:two reduction rings with gears and worms,two modulation frames to correct lateral or anteroposterior re-placement,and four connecting rods.By cranking the handle,the gears wi ll be driven,which may in turn shift t he modulation frame,then the needle co nnecting the bone with the frame can s hift the fracture ends in three dimen sions and six freedom degrees.After reduction,the fracture is fixed by the cro ssed needles linked to several groups of half-ring fixation arms,which can b e shifted and locked onto the linking rod properly.Results The apparatus was used in 32patients.All cases got anatomic reduction,and the curativ e ratio was 100%.Conclusion The external fixator for close reductio n of tibial and fibula fractures has g ood reduction and fixation effect,a nd the design provides a very good clinical therap eutic method for close reduction of t ibial and fibula fractures.[
