The sagittal shape of the spine, particularly its sagittal balance, currently is being extensively investigated. The major purpose of this study is to examine the measurement repeatability of SpineView software, which calculates 13 independent variables, to shorten and facilitate the measurement of lateral spinal radiographs; another purpose is to collect(More)
STUDY DESIGN A 3-dimensional (3-D) analysis of asymptomatic spinal and pelvic alignment. OBJECTIVE To obtain 3-D reference values of spinal and pelvic parameters, vertebral and intervertebral orientations. SUMMARY OF BACKGROUND DATA Referential values of spine and pelvis alignment are essential for the assessment of posture and balance. However, only(More)
OBJECTIVE To describe and evaluate a fast accurate stereoradiographic 3D-reconstruction method of the spine. BACKGROUND Stereoradiographic methods based on anatomical landmarks identification are the only ones providing information on 3D-deformities of the spine in a standing position, but require 2-4 h for the whole spine, making the method inadequate(More)
Analyzing standing posture requires a precise measure of the orientation of the various body segments with respect to the gravitational vector. We studied the posture variability of 34 healthy upright standing subjects. Using a force platform combined with a powerful stereoradiographic technique, we acquired the spine and pelvis three-dimensional (3D)(More)
Three-dimensional mechanical modelling of muscles is essential for various biomechanical applications and clinical evaluation, but it requires a tedious manual processing of numerous images. A muscle reconstruction method is presented based on a reduced set of images to generate an approximate parametric object from basic dimensions of muscle contours. A(More)
BACKGROUND Although some clinical reports suggest patient-specific instrumentation in TKA may improve alignment, reduce surgical time, and lower hospital costs, it is unknown whether it improves pain- and function-related outcomes and gait. QUESTIONS/PURPOSES We hypothesized that TKA performed with patient-specific instrumentation would improve(More)
Many believe that the fetus spine had only one curvature from cranial to caudal which is a global kyphosis and that the lumbosacral lordosis appears with the erect posture. They agree that the sacrum of Homo sapiens is not positioned posteriorly at birth and that it is during the first few years that the sacrum, in humans, moves dorsally in relation with(More)
Lower limb rotational profile in children may cause great concern to parents and relatives. In order to give parents clear information, there is a need for referential studies giving normative data of lower limb rotational profile and its normal changes expected over growth. Our aim was to collect a large clinical series of healthy children, out of a(More)
We studied and conceptually analyzed a retrospective case series of patients with airway compression due to an anterior vertebral body protrusion. The goal was to describe the pathology, methods of management, and a new concept for quantifying deformity. Case reports have been published on this pathology, but there has been no case series to date. In this(More)
The joint coordinates systems (JCS) of the hip, knee, and ankle have been extensively described [1, 2, 3]. The principle is to embed a flexion-extension (FE) axis in the proximal segment and an internalexternal rotation (IER) (or adduction-abduction (AA)) axis in the distal segment, following anatomical or functional directions. For the joint displacements,(More)
