1. A surgical kit for performing osteotomy, comprising:
at least two lateral plates that include
a first lateral plate adapted to have a top surface configured to face away from a bone when implanted, a bottom surface configured to be in contact with the bone when implanted, a first proximal end and a first distal end aligned along a longitudinal axis of the bone, wherein the first lateral plate has one or more through-holes on its surface configured to fix to the bone,
a second lateral plate fixed over the bone adjacent to the first lateral plate having a top surface configured to face away from the bone when implanted, a bottom surface configured to be in contact with the bone when implanted, a second proximal end and a second distal end aligned along a longitudinal axis of the bone, wherein the second lateral plate has one or more through-holes on its surface configured to fix to the bone;
a central plate slidably placed over the first lateral plate and the second lateral plate, wherein the central plate has a top surface configured to face away from the at least two lateral plates when implanted, a bottom surface configured to be in contact with the at least two lateral plates when implanted, a first end and a second end aligned along a longitudinal axis of the bone, and wherein the central plate further comprises at least two compression holes at its center and one or more locking holes proximal to the compression holes,
wherein the two lateral plates are configured to be fixed on a bone in anatomical alignment by the central plate, and the central plate is placed on the two lateral plates, thereby allowing the fixed lateral plates to preserve the anatomical alignment and measure the exact distance between two lateral plates, the distance between the two lateral plates is adapted to the amount of shortening osteotomy,
wherein the central plate has one or more through-holes on its surface configured to securely fix the at least two lateral plates to the bone at an exact distance equal to the amount of bone shortening osteotomy via one or more fasteners, thereby allowing an accurate amount of bone shortening and anatomical reduction and fixation of osteotomy site.
