The Impact of Upper Instrumented Vertebra Orientation on Proximal Junctional Kyphosis-A Novel and Fixed Parameter, Fused Spinopelvic Angle.

ABSTRACT:

Study design

A retrospective study.

Objectives

To evaluate the impact of upper instrumented vertebra (UIV) orientation including the fused spinopelvic angle (FSPA) on proximal junctional kyphosis (PJK).

Summary of background data

PJK is a challenging complication after adult spinal deformity (ASD) surgery. Some study proposed UIV orientation act as a risk factor of PJK, but there remain debates because UIV orientation is changed by position. Therefore, we investigated the relationship between the FSPA, a novel parameter for the relationship between UIV and pelvis which did not changed by position, and PJK.

Methods

ASD patients underwent long-segment fusion to pelvis and followed-up for more than 2 years were included. Comparative analysis was performed on spino
