Background Vertebral arthrodesis for degenerative pathology of the lumbar spine still
remains burdened by clinical problems with significant negative results. The introduction of …

Study Design: This is a retrospective cohort study. Objective: The objective of this study was
to further elucidate the relationship between pelvic incidence-lumbar lordosis (PI-LL) …

OBJECTIVE This study aimed to investigate the impact of pelvic incidence (PI) and lumbar
lordosis (LL) matching on health-related quality of life (HRQOL) outcomes in patients …

Objective The demand for spinal fusion is increasing, with concurrent reports of iatrogenic
adult spinal deformity (flatback deformity) possibly due to inappropriate lordosis distribution …

Purpose Several risk factors and causes of adjacent segment disease have been debated;
however, no quantitative relationship to spino-pelvic parameters has been established so …

ABSTRACT BACKGROUND CONTEXT Interbody fusion, including: transforaminal (TLIF),
posterior (PLIF), anterior (ALIF), and lateral (LLIF); effectively treat lumbar degenerative …

Background Symptomatic adjacent segment disease (ASDis) is a major complication
following spinal fusion. Sagittal spinopelvic imbalance may contribute to the development of …

Not restoring the adequate lumbar lordosis during lumbar fusion surgery may result in
mechanical low back pain, sagittal unbalance and adjacent segment degeneration. The …

The measure of radiographic pelvic and spinal parameters for sagittal balance analysis has
gained importance in reconstructive surgery of the spine and particularly in degenerative …

Background Adjacent segment disease (ASD) is an acknowledged problem of posterior
lumbar interbody fusion (PLIF). Many studies have been reported concerning the role of …
