Claim 0:
1. An augmented spanning fixation bone plate assembly comprising:
a) a spanning fixation bone plate comprising:
a first end having an aperture therethrough;
a second end having an aperture therethrough;
a body portion configured between said first end and said second end and comprising:
a top surface;
side surfaces;
a bone contacting surface;

wherein the spanning fixation bone plate extends a length along a length axis from said first end to said second end;
wherein a first fastener extends through the aperture in the first end to permit attachment of the first end to a first bone and wherein a second fastener extends through the aperture in the second end to permit attachment of the second end to a second bone; and

b) an augmentation fixation bone plate detachably attached to the spanning fixation bone plate and comprising:
i) a length from a first end to a second end;
ii) an attachment portion having a retention aperture forming an interface surface that retains the augmentation fixation bone plate on the spanning fixation bone plate,
wherein the retention aperture is a through aperture forming a closed opening in the attachment portion;

iii) a first wing extending from the attachment portion to said first end of said augmentation fixation bone plate and having a bone contacting surface and a fastener aperture;
wherein the first wing extends laterally from the length axis of the spanning fixation bone plate to the first end of the augmentation fixation bone plate and wherein the bone contacting surface of the first wing is in planar alignment with the bone contacting surface of the spanning fixation bone plate;
iv) a second wing extending from the attachment portion to said second end of said augmentation fixation bone plate and having a bone contacting surface and a fastener aperture;

wherein the second wing extends laterally from the length axis of the spanning fixation bone plate to the second end of the augmentation fixation bone plate and wherein the bone contacting surface of the second wing is in planar alignment with the bone contacting surface of the spanning fixation bone plate;
wherein the retention aperture extends around the spanning fixation bone plate;
wherein the augmentation fixation bone plate is configured to slidably engage with the body portion of the spanning fixation bone plate;

wherein a fastener extends through the fastener aperture of the first wing to permit attachment of the first wing to a third bone that is a different bone from the first or second bone; and
wherein a fastener extends through the fastener aperture of the second wing to permit attachment of the second wing to said third or a fourth bone that is a different bone from the first or second bone.
