Several studies describe sagittal realignment for flat back and related kyphotic decompensation. Official guidelines for sagittal and the frontal realignment have not been developed. In this retrospective study, the authors examined 10 patients with flat back syndrome and treated a related kyphotic decompensation syndrome by posterior wedge osteotomy. ⋯ One-level lumbar osteotomy is a safe procedure to correct sagittal unbalance. Peroperative lordosis correction allows reliable correction planning. The remaining problem is planning for frontal balance correction.
