A bone plate includes a first three-part combination hole extending through a proximal portion of the plate, a first portion configured to engage a threaded head portion of a bone fixation element, a second portion configured to receive a bone fixation element along an axis substantially perpendicular to a longitudinal axis of the bone and a third portion defining a screw axis extending toward the distal end of the elongated body at a non-perpendicular angle relative to the longitudinal axis in combination with a first two-part combination hole extending through the proximal portion, a first threaded portion configured to engage a threaded head portion of a bone fixation element and a second portion defining an elongated slot extending along a longitudinal axis of the plate for receiving a bone fixation element so that the plate may slide along its longitudinal axis relative to the bone fixation element.
