Fig. 1

Dynamic compression principle. Since the screw is inserted into an inclined and transverse cylindrical holes in DCP, the horizontal movement of the screw head can occur along the screw hole. This movement results in movement of the bone fragment relative to the plate and leads to compression of the fracture site. DCP: Dynamic compression plate.

(E, F) Distal femur fracture was fixed with locking compression plate (LCP), using bridging plating technique and bone union was achieved one year after surgery.

(G, H) Patella was fixed with vertical and cerclage wiring. Intraarticular proximal tibia fracture was fixed with LCP and a lag screw using a compression plating technique. Bony union was uneventfully achieved.
