Dysplastic spondylolisthesis is a severe pathological condition, based on dysplastic changes in the lumbosacral part of spine, that causes asymmetry junction. The appropriate therapeutic algorithm remains controversial. As gold standard, surgical reposition slipped vertebra and 360° fusion affected spinal segment preferred. Thirty-two patients were operated between years 2005 2018. Different te...

dult spinal deformity is a complex pathologic procA ess with many etiologies and several mechanisms of compensation. A complete understanding of patient-specific spinopelvic alignment is required to differentiate the origin of the deformity from postural compensatory mechanisms and, ultimately, to optimize surgical correction. Specific spinopelvic parameters have been shown to be invaluable in ...

Study Design Retrospective analysis of adolescent idiopathic scoliosis. Purpose This study aimed to investigate the influence of distinct distal fusion levels on spinopelvic parameters in patients with adolescent idiopathic scoliosis (AIS) who underwent posterior instrumentation and fusion surgery. Overview of Literature The distal fusion level selection in treatment of AIS is the one of mi...

ABSTRACT Introduction: Spinopelvic parameters related to sagittal balance have become increasinglyimportantamong spine surgeons due their correlation with patient satisfaction rates. Objective: The goal of this study was evaluate changes in spinal after lumbar surgery using PLIF, the posterior interbody fusion technique. Methods: sample consisted adult patients degenerative disease submitted ar...

BACKGROUND Sagittal spinopelvic alignment changes associated with degenerative facet joint arthritis have been assessed in a few studies. It has been documented that patients with facet joint degeneration have higher pelvic incidence, but the relationship between facet joint degeneration and other sagittal spinopelvic alignment parameters is still disputed. Our purpose was to evaluate the corre...

OBJECTIVE The purpose of this study was to evaluate the differences in sagittal spinopelvic alignment between lumbar degenerative spondylolisthesis (DSPL) and degenerative spinal stenosis (DSS). METHODS Seventy patients with DSPL and 72 patients with DSS who were treated with lumbar interbody fusion surgery were included in this study. The following spinopelvic parameters were measured on who...

Objective Recent studies have demonstrated sagittal spinal balance was more important than coronal balance in terms of clinical result of surgery for adult spinal deformity. Notably, Schwab reported one of the target spinopelvic parameters for corrective surgery was that lumbar lordosis (LL) should be within +/10 degrees of pelvic incidence (PI). The present study was aimed to investigate wheth...
