Webbscrew rotation pushes the material upstream), the flow conditions are very similar to those in the metering zone of a single-screw extruder [3]. In this case, the average shear rate. g is usually expressed as [4–8]:. g = 2pN R 60h (1) where N is the rotation speed (expressed in rpm), R is the screw radius, and h is the channel depth. WebbLag screw principles for the radial head. In two-part partial articular fractures of the radial head, fixation can be achieved by lag screws. The thread pulls the opposite bone fragment towards the head of the screw placing the fracture ends under compression. The portion of the thread in the gliding hole does not purchase in the surrounding bone.
