Novel, safe, and easy spinal osteotomy for regional kyphotic deformities

Objective: This study aimed to assess the efficacy and safety of a newly developed transpedicular, anterior open-wedge osteotomy procedure with lamina preservation to correct sagittal imbalance in regional kyphotic deformities following compression fractures. Methods: All seven patients [four females and three males; mean (range) age, 67 (56-78) years] included in this study underwent surgery between May 2005 and May 2016 for symptomatic, rigid kyphosis secondary to compression fractures. Transpedicular, anterior open-wedge osteotomy with lamina preservation was performed in all patients using an osteotome to create a transverse fracture in the vertebral body through bilateral pedicles and an anterior open-wedge space filled with compacted bone graft to correct kyphosis. Pre- and post-operative kyphotic Cobb angles were evaluated, and the volume of intra-operative blood loss was measured. Results: The pre- and post-operative kyphotic Cobb angle was 35.3° and 17.7°, respectively (p
