Purpose The goal of this study was to characterize the spino-pelvic realignment and the
maintenance of that realignment by the upper-most instrumented vertebra (UIV) for adult …

Object Lumbopelvic fixation provides biomechanical support to the base of the long
constructs used for adult spinal deformity. However, the failure rate of the lumbopelvic …

Abstract Background Context Proximal junctional kyphosis (PJK) and proximal junctional
failure (PJF) are common problems after long-segment (> 5 levels) thoracolumbar …

Background Opposed to proximal junctional kyphosis and proximal junctional failure, their
distal equivalents, distal junctional kyphosis and failure (DJK/DJF) have received less …

Abstract Study Design Retrospective case series of surgically treated adult patients with
fixed sagittal imbalance. Objective To assess clinical and radiographic changes after pedicle …

Study Type Retrospective review. Introduction Sagittal imbalance has been associated with
lower health-related quality of life outcomes, and restoration of imbalance is associated with …

Purpose To examine the risk factors of proximal junctional kyphosis (PJK) after surgery for
adult spinal deformity (ASD) focusing on rod contour. Methods Sixty-three patients with ASD …

Study Design. A retrospective cohort study. Objectives. The aim of this study was to evaluate
radiographic and patient-reported outcomes at minimum 2 years after revision surgery for …

Study Design: This was a retrospective multicentric study. Objective: The objective of this
study was to determine the different risk factors for development of proximal junctional …

Objective Proximal junctional kyphosis (PJK) is radiologic finding, and is defined as
kyphosis of> 10 at the proximal end of a construct. The aim of this study is to identify factors …
