WebJan 1, 2012 · The mechanical principle of a locked screw plate. (A) The plate sits slightly of the bone. (B) Tightening of the screw locks the screw head within the plate. The plate is not drawn toward the bone and there is no compression b/w the bone and the plate. The flux is bone/ screw/ plate/ screw/ bone. 40. bird cleaning \u0026 hygieneWebBackground: Effective fixation of fracture requires careful selection of a suitable implant to provide stability and durability. Implant with a feature of locking plate (LP) has been used widely for treating distal fractures in femur because of its favourable clinical outcome, but its potential in fixing proximal fractures in the subtrochancteric region has yet to be explored. bird cleaning serviceWebThis study aims to compare the biomechanical stability of 3 different types of scaphoid fracture fixation in a scaphoid nonunion model.
