For patients with significant spinal deformity, the pedicle subtraction osteotomy provides a powerful means for correction, albeit with high morbidity. With the trend toward minimally invasive spine surgery, multiple less invasive techniques have been devised; however, there seems to be an upper limit to the degree of correction possible. The mini–open pedicle subtraction osteotomy addresses these limitations by minimizing the extent of soft tissue destruction needed to perform the osteotomy and by using the rod-cantilever technique to achieve maximum lordosis. Preliminary data are promising, with significant improvements in patient-reported clinical outcome measures as well as coronal and sagittal alignment.
