The treatment of three- or 4-part proximal humerus fractures is still a matter of scientific discussion. The following study presents the results of a combined procedure using limited invasive fixation techniques for reconstruction of the humerus head and retrograde intramedullary wiring with elastic nails for the treatment of displaced three- or 4-part(More)
We report on four cases of fetal cervical tumor, comprising three lymphangiomas and one teratoma, evaluated by ultrasound and magnetic resonance imaging (MRI) between 26 and 37 weeks' gestation. The aim was to investigate the use of virtual bronchoscopy to evaluate fetal airway patency in each case. A three-dimensional (3D) model of the airway was created(More)
The term ‘virtual bronchoscopy’ describes the creation and evaluation of representations of the bronchial tree and surrounding structures using spatial information derived from imaging sources other than the bronchoscope itself. Initially, this referred to two-dimensional and later three-dimensional (3D) bronchial tree representations generated from(More)
OBJECTIVE To generate physical fetal models using images obtained by three-dimensional ultrasonography (3DUS), magnetic resonance imaging (MRI) and computed tomography (CT) to guide additive manufacturing technology. METHODS Images from 33 fetuses, including three sets of twins, were used. Fifteen fetuses were normal and evaluated only by 3DUS. Eighteen(More)
