Purpose

compare the radiological results in sagittal balance correction obtained with pedicle subtraction osteotomy (PSO) versus anterior-posterior osteotomy (APO) by double approach in adults.

Material and Methods

between January of 2001 and July of 2009, fifty-eight vertebral osteotomies were carried out in fifty-six patients: 9 Smith-Petersen osteotomy (SPO), one vertebral resection osteotomy (VRO), 30 anterior-posterior osteotomies (APO) and 18 pedicle subtraction osteotomies (PSO), being the lasts two groups the sample studied (48 osteotomies). The mean age of the patients was 56.3 years (17–72). Initial diagnose was: 28 posttraumathic kyphosis, 7 postsurgical kyphosis, 7 adult degenerative disease, 4 ankylosing spondylitis and 2 congenital kyphoscoliosis. We evaluated the preoperative standing radiographs, the postoperative and at final follow-up by digital measurements with iPACS system viewer (© Real Time Image, USA, 2001). The mean follow-up was 54 months (6–98), and complications were analized.
