Ideal length of accessory rod for the prevention of rod fracture after pedicle subtraction osteotomy in adult spinal deformity: short or long?

CONCLUSIONS: In this study the authors found that the D-shaped configuration of the AR and lower end of the AR below S1-2 (i.e., long AR) could be preventive methods for reducing RF after deformity correction performed using PSO and the AR technique for ASD. Here, the authors have provided the first comprehensive outline for the AR technique. These findings could establish effective guidelines for spine surgeons.PMID:38306637 | DOI:10.3171/2023.12.SPINE23937
