A bone plating system includes a plate member and a first bone screw. The plate member defines a longitudinal axis and has a top surface and a bottom surface. The plate member further defines an elongated hole extending between the top surface and the bottom surface with a width in a direction generally perpendicular to the elongated axis and a length with a greater dimension in a direction generally parallel to the elongated axis. The elongated hole is defined by a sidewall having a spherical cross section in the direction generally perpendicular to the elongated axis. The sidewall has a threading. The first bone screw has a threaded and spherical head for threadably engaging the elongated hole. The threading extends completely around the sidewall of the elongated hole such that the first bone screw may threadably engage the elongated hole anywhere along the length.
