Abstract
Materials and methods 78 consecutive patients (63 women 15 men) were included in the study, mean age of 66 years (range 60-77), surgically treated at our Division between 2000 and 2005. In all cases the diagnosis was idiopathic scoliosis, with positive sagittal imbalance. In 29 cases (37.2 %) a previous arthrodesis was performed. All patients were treated with posterior arthrodesis with pedicle instrumentation and a pedicle subtraction osteotomy (PSO) in 17 cases and Smith Petersen osteotomy ( SPO ) at multiple levels in 25 cases. The clinical and radiographic questionnaires (Oswestry, VAS) filled in before and after surgery and at final follow-up were evaluated.
Highlights
The proximal junctional kyphosis (PJK) occurs from 17% to 39% after posterior arthrodesis for spinal deformity
The aim of this study is to verify a possible correlation between PJK

Summary
The aim of this study is to verify a possible correlation between PJK and pelvic incidence (PI) in the treatment of adult scoliosis
