Closure of L3 pedicle subtraction osteotomy via an open-bottom hinged table in 3D video
Iatrogenic flat back deformity generally can be treated with a pedicle subtraction osteotomy (PSO) (Chan et al., 2018; Lu and Chou, 2007). One of the difficulties with PSO is that a controlled closure can sometimes be problematic in that there may be translation of the spine, manual pushing of the spine, and significant stress on the pedicle screws, which may risk loosening. The authors present a video of their surgical technique for PSO closed by passive closure using an open-bottom hinged table. This allows the osteotomy to be closed without any force on the screws and without significant manual forces on the spinal column. 1Department of Neurosurgery, University of California, San Francisco, California; 2Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei; 3School of Medicine, National Yang-Ming University, Taipei, Taiwan; and 4University of California, San Francisco, California **Intro music: "Daybreak" by Graeme Rosner Chih-Chang Chang, MD,1–3 Praveen V.
