Axial compression of fracture using dynamic compression nail. (a) The compression screw is placed eccentrically away from the fracture site through the oval hole of the nail (b) Nail is attempted to be pulled out to ensure eccentric placement of the screw, proximal locking is completed, (c) tightening of the compression screw forces the spherical screw head to glide down the sloping edge of the oval hole resulting into the axial compression and stable fixation.
