Quick-connect drill guide

A drill guide assembly, comprising:

• a. a drill guide including:
• a body having a proximal end and a distal end, the distal end having a bone plate engaging portion;
• at least one lobe projecting radially outward from an outer surface of the bone plate-engaging portion, such that the distal end of the body has a first distal end diameter, measured at a first portion of the distal end of the body including the at least one lobe, that is greater than a second distal end diameter, measured at a second portion of the distal end of the body which does not include the at least one lobe;
• an internal guide passage extending through the body between the proximal and distal ends of the body;
• a flange extending outward from the body configured to engage the top surface of the bone plate, the flange including at least one radial end extending away from the body in a direction of the at least one lobe;
• and
• at least one pin extending from the flange axially alongside the distal end of the body;
• and
• b. a bone plate having a bone-engaging side, an top surface opposite to the bone-engaging surface, a bone screw hole extending through the top and bone-engaging surfaces of the bone plate adapted to receive a bone screw, and at least one aperture formed in the bone plate at a lateral side of the bone screw hole, the bone screw hole including:
• a threaded portion;
• and
• a drill guide-engaging portion, the drill guide-engaging portion disposed between the threaded portion and the bone-engaging side of the bone plate, the drill guide-engaging portion having at least one cut-out formed in a sidewall of the bone screw hole that is sized and shaped to correspond to the at least one lobe;
• wherein the plate-engaging portion of the drill guide is configured to be slidably received in the bone screw hole of the bone plate such that the at least one lobe is received in the at least one cut-out, and the at least one pin is received in the at least one aperture to removably couple the drill guide to the bone plate to allow drilling a hole in a bone through the internal guide passage in alignment with the bone screw hole.

• a. a bone plate having a bone-engaging surface, an top surface opposite to the bone-engaging surface, a bone screw hole extending through the top and bone-engaging surfaces of the bone plate adapted to receive a bone screw, and first and second apertures formed in the bone plate about opposed lateral sides of the bone screw hole, the bone screw hole including:
• a bone screw-engaging threaded portion;
• and
• a drill guide-engaging portion, the drill guide-engaging portion disposed between the bone screw-engaging threaded portion and the bone-engaging surface of the bone plate, the drill guide-engaging portion including at least one cut-out formed in a sidewall of the bone screw hole;

• an internal guide passage extending through the body between the proximal and distal ends of the body;
• a flange extending radially outward from the body configured to engage the top surface of the bone plate, the flange including a first end spaced apart from a first side of the body in a direction of the at least one lobe and a second end spaced apart from a second opposite side of the body;
• and
• first and second pins extending from the respective first and second ends of the flange axially alongside the distal end of the body;
• wherein the plate-engaging portion of the drill guide is configured to be slidably received in the bone screw hole of the bone plate such that the at least one lobe is received in the at least one cut-out, and the first and second pins are received in the first and second apertures to removably couple the drill guide to the bone plate to allow drilling a hole in a bone through the internal guide passage in alignment with the bone screw hole.
