All patients underwent posterior one-stage decompression with sacral dome osteotomy, L5 vertebrectomy with L5-S1 discectomy, and partial reduction and instrumented fusion in a single posterior approach. The mean age and follow-up were, respectively, 20 years and 65 months. The mean preoperative %...
Next, the patient was moved to the prone position, and L5/S1 posterior lumbar interbody fusion was performed using a lordotic cage loaded with local bone. The thoracolumbar deformity was corrected using rod-cantilever and/or rod-derotation techniques. The volume of preserved local bone graft was...

Reduction of lumbar spondylolisthesis during spinal fusion surgery is important for improving the fusion rate and restoring the sagittal alignment. Despite the variety of reduction methods, the fundamental mechanics of lumbar spondylolisthesis reduction remain unclear. This study aimed to investigate the biom...
