To describe a modification to the traditional Smith-Petersen Osteotomy, which involves removing the posterior column of bone at a single level, however, instead of gaining approximately 10° of correction, this modification results in 20°-25° of sagittal correction with the use of helper rods. The Super-Smith Petersen Osteotomy is a modification of the Smith-Petersen Osteotomy that is a single-level osteotomy, that with the use of helper rods, one can obtain a larger degree of correction than the traditional Smith Petersen Osteotomy, with less technical demand compared to a pedicle subtraction osteotomy or vertebral column resection.
