Several algorithms are currently in use for evaluating vertebral deformities from plain lateral radiographs of the lumbar and thoracic spine. However, the effects of measurement imprecision as well as uncertainties over image magnification on the cor

Fatigue-induced microdamage in bone contributes to stress and fragility fractures and acts as a stimulus for bone remodelling. Detecting such microdamage is difficult as pre-existing microdamage sustained in vivo must be differentiated from artefactu

Purpose: To evaluate age- and gender-related mechanical properties and bone mineral density (BMD) of the proximal humerus at different levels and regions. Materials and Methods: Mechanical indentation testing, DXA, QCT, pQCT and the radiogrammetry (C

Incident vertebral deformities are commonly defined by observed changes in height between measurements on two consecutive radiographs. However, conventional radiographs are subject to magnification, and this magnification may differ between films, le

Die Osteoporose wird im wesentlichen durch die Knochendichtemessung diagnostiziert. Dabei bilden die Zwei-Spektren Untersuchungen heute die Grundlage fur eine gut reproduzierbare und richtige Messung. Zur Einschatzung eines materialbezogenen Frakturr

The problem of quantifying the structure of cancellous bone has been addressed in the past by histomorphometry and more recently by imaging techniques using X-ray attenuation. The current approaches compute and describe parts of the construction of t

□Background: The prevalence of radiographically defined vertebral deformities, as a marker of vertebral osteoporosis, was calculated in a population based cross-sectional survey in Germany. □Method: Lateral spine X-rays were taken according to a

Purpose The accuracy and reproducibility of morphometric measurements (Morphometric X-ray Absorptiometry = MXA) of vertebrae were determined. The significant difference of the change in height of vertebral bodies in follow-up studies was computed for
