1. A drill guide, comprising:
an outer body extending from a proximal end to a distal end and having a slot disposed proximate the proximal end;
an inner body disposed in the outer body;
a lever coupled to the inner body through the slot, wherein rotation of the lever to a first position of the lever translates the inner body towards the distal end of the outer body to lock the outer body to a bone plate, and when the lever is in a second position the outer body may be removed from the bone plate; and
a spring disposed within the outer body and beneath a portion of the inner body, wherein the spring biases the inner body in a direction away from the distal end of the outer body.
