Biomechanical Advantages of Novel Duet Screws Plus Bilateral Satellite Rods Fixation in the Correction Surgery for Adult Spinal Deformity

ABSTRACT Purpose Adult spinal deformity (ASD) patients undergoing pedicle subtraction osteotomy (PSO) with long fusion to the pelvis have a high risk of rod failure at the PSO level or adjacent areas. This study aimed to investigate the biomechanical advantages of novel duet screws (multiaxial screw...
