Bone plates and methods of using the bone plates for adjoining bone fragments are disclosed herein. A device for adjoining at least two bone fragments includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of at least one filling material and an inner lumen for passage of a light source; a conformable bone plate releasably engaging the distal end of the delivery catheter, wherein the conformable bone plate has a first surface, a second surface, a proximal end, and a distal end and at least one aperture extending from the first surface to the second surface for receiving a fastener; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and a delivery system housing the at least one filling material.

1. An extramedullary flexible expandable polymer pad for adjoining at least two craniomaxillofacial bone fragments comprising: a first bone contacting surface and an opposing second outer surface each having a first area, wherein the first bone contacting surface is textured with one or more ridges,
1. An extramedullary flexible expandable polymer pad for adjoining at least two craniomaxillofacial bone fragments comprising: a first bone contacting surface and an opposing second outer surface each having a first area, wherein the first bone contacting surface is textured with one or more ridges, ribs or bumps to help engage the pad against the at least two bone fragments;a left side surface extending between a left edge of the first bone contacting surface and a left edge of the second outer surface and an opposing right side surface extending between a right edge of the first bone contacting surface and a right edge of the second outer surface, each having a second area, wherein the first area is greater than the second area;a front surface extending between a front edge of the first bone contacting surface and a front edge of the second outer surface and an opposing back surface extending between a back edge of the first bone contacting surface and a back edge of the second outer surface, each having a third area, wherein the first bone contacting surface, the second outer surface, the left side surface, the right side surface, the front surface and the back surface create an inner space within the pad;a major longitudinal axis running from the left side surface to the right side surface;a minor longitudinal axis running from the first bone contacting surface to the second outer surface, the minor longitudinal axis being transverse to the major longitudinal axis;an opening positioned only through the right side surface and extending along the major longitudinal axis, wherein the opening is sufficiently designed to engage a delivery catheter having an outer diameter of about 3 mm;a filling material contained within the inner space of the pad, wherein the filling material has a liquid consistency and viscosity ranging from about 650 cP to about 450 cP so as to be deliverable to the pad through an inner void of the delivery catheter using low pressure delivery, and wherein the filling material is hardenable using visible light emitted from a light source sized to pass through an inner lumen of the delivery catheter and into the inner space of the pad along the major longitudinal axis of the pad;a coating on at least one surface of the pad, wherein the coating is selected from at least one of an antibiotic drug, a bone glue, a protein or a growth factor; andfive through apertures extending from the second outer surface to the first bone contacting surface along the minor longitudinal axis such that the five through apertures are transverse to the opening, wherein a corner through aperture of the five through apertures is positioned at each corner of the pad and a centered through aperture of the five through apertures is positioned in the middle of the pad;wherein the centered through aperture of the five through apertures is centered at the intersection of the major longitudinal axis and the minor longitudinal axis for receiving a fastener,wherein the corner through apertures of the five through apertures are at the periphery of the pad for receiving a fastener, andwherein, when the filling material is delivered to the inner space of the pad, the pad moves from a first compact position to a second expanded position and is contoured to engage against the at least two bone fragments. 2. The pad of claim 1 wherein the adjoining of the at least two bone fragments occurs at an exterior surface of the bone fragments. 3. The pad of claim 1 wherein the at least two bone fragments are bones of the face. 4. The pad of claim 1 wherein the flexible expandable polymer pad is polyethylene terephthalate. 5. The pad of claim 1 wherein at least one of the first bone contacting surface or the second outer surface is textured to conform the pad to a shape of the bone fragments. 6. The pad of claim 1 wherein the filing material alone, without aid of an additional reinforcing element, provides strength required to adjoin the at least two bone fragments. 7. The pad of claim 1 wherein the filling material is a single-component, solvent-free adhesive. 8. The pad of claim 1 wherein the light source includes a light pipe and an optical lens, and wherein the optical lens guides the visible light into the pad.
