“…PSO in posttraumatic kyphotic correction showed no neurologic complication in many series. 9,11,12,26 The construct used in our study with 4 screws above and below the osteotomy level led to stability of the instrumented vertebrae, and adding the cross links to the construct added no benefits, as all cases showed good fusion with no pseudoarthrosis.…”

“…However, the PVCR technique can result in a high rate of complications, including neural injury during the perioperative period and fixation failure caused by nonunion or pseudo articulation formation 3,16,18–23 . PSO can achieve 30°–40° correction in a single segment 5,24,25 . The advantages of PSO are a shorter operation time, reduced surgical trauma, and lower complication rates than PVCR.…”

“…However, the osteotomy itself is inherently destabilizing to the spinal column, and requires rigid fixation posteriorly to minimize catastrophic neurologic failure [2,3]. While not exceptionally common, there is a subset of spinal deformity patients with fixed sagittal imbalance that require such posterior osteotomies to optimize the surgical correction of their deformities [4][5][6][7][8][9]. Transverse connectors may play a pivotal role in patients requiring a PSO for the management of a fixed sagittal deformity.…”

“…Transverse connectors may play a pivotal role in patients requiring a PSO for the management of a fixed sagittal deformity. While PSO is a technique more commonly performed in the lumbar spine, recent literature has shown thoracic PSO can be performed safely with good improvements in regional thoracic sagittal alignment, while avoiding the potential morbidity of an anterior exposure [2,3,[5][6][7][8]10]. The thoracic PSO is unique, as the correction occurs through all three columns of the spine and includes resection of the costovertebral joints at the surrounding vertebral segments, and may therefore predispose it to a degree of instability not often encountered in other clinical scenarios [2].…”
