pelvic parameter correction?
Schwab Frank; Lafage Virginie; Patel Ashish; Hart Robert ;
• Pedicle subtraction osteotomy– Correction of sagittal spinal
malalignment
• Impact of PSO level ?– Caudal lumbar PSO results in
greater correction of SVA ?
Effect of PSO level on immediate post-operative spino-pelvic alignment?
PurposePurpose
• Evaluate Evaluate radiographic changesradiographic changes of spinal and pelvic parameters of spinal and pelvic parameters induced by induced by PSO surgeryPSO surgery
• Define Define differencesdifferences regarding regarding spinal and pelvic parameters spinal and pelvic parameters related to level and degreerelated to level and degree of of osteotomy performed.osteotomy performed.
