Background The T1-S1 distance to evaluate spinal length is traditionally measured as a
straight line on an anteroposterior radiograph. However, this method may not reflect the true …

Background and objective The aim of this study was to validate a new program which aims
at measuring the three-dimensional length of the spine's midline based on two calibrated …

Purpose Knowledge about spinal length and subsequently growth of each individual patient
with adolescent idiopathic scoliosis (AIS) helps with accurate timing of both conservative …

Abstract Study Design The accuracy and repeatability of a novel sagittal spine length (SSL)
radiographic measurement was examined using photographic and radiographic imaging …

Background: Current assessment of spine growth for patients undergoing growth friendly
surgical treatment for early-onset scoliosis (EOS) is the use of serial, 1-dimensional standard …

Purpose Large registries are increasingly at the forefront of modern pediatric spine research,
with manual, centralized, trained radiographic measurement serving as the gold standard for …

The aim of this study was to evaluate the precision of three-dimensional geometry compared
with computed tomography (CT) images. This retrospective study included patients who had …

Abstract Background Context One of the characteristics of reported observations in
adolescent idiopathic scoliosis (AIS) is that the thoracic spine is longer anteriorly than …

The paper proposes a method for using the relative values of linear dimensions for spine
structures, which are necessary to compare the results obtained from digital and …

Purpose Although adolescent idiopathic scoliosis (AIS) is known to impact the 3D orientation
of the spine and pelvis, the impact of the vertebral position relative to the X-ray scanner on …
