Background Castellvi type III and IV lumbosacral transitional vertebrae (LSTVs) are fused to
the sacrum. In these cases, the pelvic incidence (PI) and pelvic tilt (PT) may vary according …

Functional spinopelvic parameters are crucial for describing spinal alignment (SA), but this
is susceptible to variation. Anatomically fixed pelvic shape is defined by the parameters …

Study Design. Prospectively collected survey study Objective. The aim of this study was to
determine the consistency with which spinopelvic parameters (SPP) are determined in …

Functional spinopelvic parameters are crucial for describing spinal alignment (SA), but this

Purpose Transitional lumbosacral vertebrae (TLSV) are a congenital anomaly of the
lumbosacral region that is characterized by the presence of a vertebra with morphological …

Purpose Optimization of spinopelvic sagittal parameters in spinal deformity surgery have
been shown to correlate with surgical outcomes. Commonly used parameters include pelvic …

Abstract Study Design Retrospective radiographic review. Objectives To understand the
effect of variability in sacral endplate selection in transitional lumbosacral vertebrae (TLSV) …

OBJECTIVE The aim of this study was to determine if spinal deformity patients with L5
sacralization should have pelvic incidence (PI) and other spinopelvic parameters measured …

Background Transitional lumbosacral vertebra presents in 2 forms based on its origin:
sacralization and lumbarization. These patients have 2 options for sacral endplates (upper …

Purpose To test the vertical posterior vertebral angles (VPVA) of the most caudal lumbar
segments measured on EOS to identify and classify the lumbosacral transitional vertebra …
