US Patent 10206692 Osteotomy guide and method of using the same

Osteotomy tools and procedures are provided that include a sets of guides in which pins are placed through conduits in the guides with a close tolerance and into the bone at predetermined angles. One pin is placed at a correction angle subtending from one of a pair of parallel pins placed across an osteotomy site. After the osteotomy is completed, a bone correction is achieved by rotating the pin at the correction angle to be parallel to the one of the parallel pins located across the osteotomy site. A parallel pin guide is placed over these two pins to maintain the bone correction and stabilize the osteotomy, allowing fixation of the corrected bone segments.
