WebWhen using anything less stable than a reconstruction plate, two points of fixation should be applied. This can be: Two lag screws. Two plates. 3D plate (such as a ladder, box, or strut plate) A single stronger plate in combination with an arch bar. The illustration shows Champy's ideal lines of osteosynthesis for symphysis fractures. WebBackground: 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. phonograph record crossword
