Biomechanical in vitro comparison between anterior column realignment and pedicle subtraction osteotomy for severe sagittal imbalance correction

The Dataset collects the Range of Motion (RoM), the Neutral Zone (NZ) and the maximum principal strains on primary rods measured on the intact specimens and following pedicle subtraction osteotomy stabilized with 2 rods (PSO-2), with 3 rods (PSO-3) and with 4 rods (PSO-4) without any cage and following also adjacent interbody cages insertion (PSO-2+Cages, PSO-3+Cages, PSO-4+Cages, respectively) and following anterior column release (ACR) with a standalone hyperlordotic ACR-Cage and with bilateral instrumentation using 2 rods (ACR-Cage+2) in all loading conditions (flexion/extension, lateral bending, axial torsion).<br>Full paper details: La Barbera L, Wilke HJ, Liebsch C, Villa T, Luca A, Galbusera F, Brayda-Bruno M.

本数据集收录了完整标本的相关数据，以及经双棒（PSO-2）、三棒（PSO-3）、四棒（PSO-4）内固定的椎弓根截骨术（pedicle subtraction osteotomy, PSO）标本（未置入任何椎间融合器）的相关数据；同时收录了分别附加相邻节段椎间融合器植入术后的双棒固定（PSO-2+Cages）、三棒固定（PSO-3+Cages）、四棒固定（PSO-4+Cages）组标本，以及采用单独高前凸ACR融合器的前路松解术（anterior column release, ACR）标本、双侧双棒内固定的前路松解术（ACR-Cage+2）标本的活动范围（Range of Motion, RoM）、中性区（Neutral Zone, NZ）及主固定杆的最大主应变数据，所有数据均采集于屈伸、侧屈、轴向扭转各类加载工况下。
