2D measurements of cup orientation are less reliable than 3D measurements (Acta Orthop 2015; 86 (4): 485–90.)

BACKGROUND AND PURPOSE 2D analysis of metal-on-metal (MoM) hip arthroplasty (HA) has been conducted in several large series on conventional radiographs with the use of Ein Bild Roentegen Analyse (EBRA) software, but there have been no comparisons with 3D analysis in the literature. The main aim of this study was to quantify the agreement in measurements of cup version of large-diameter MoM hips...

Noncoherent 2d and 3d Sar Reconstruction from Wide-angle Measurements

This paper considers processing and visualization of radar scattering measurements from one or more wide-angle synthetic apertures. We consider both two-dimensional imaging and three-dimensional interferometric reconstructions. A point-scattering assumption is poorly suited to wideangle scattering; scattering objects within a target typically have narrow beam patterns, resulting in limited angl...

Correction of radiographic measurements of acetabular cup wear for variations in pelvis orientation

Radiographic measurement of two-dimensional acetabular cup wear is usually carried out on a series of follow-up radiographs of the patient's pelvis. Since the orientation of the pelvis might not be consistent at every X-ray examination, the resulting change in view of the wear plane introduces error into the linear wear measurement. This effect is amplified on some designs of cup in which the c...

Is the transverse acetabular ligament a reliable cup orientation guide?

BACKGROUND AND PURPOSE It is controversial whether the transverse acetabular ligament (TAL) is a reliable guide for determining the cup orientation during total hip arthroplasty (THA). We investigated the variations in TAL anatomy and the TAL-guided cup orientation. METHODS 80 hips with osteoarthritis secondary to hip dysplasia (OA) and 80 hips with osteonecrosis of the femoral head (ON) were...

Point:Counterpoint: Lung impedance measurements are/are not more useful than simpler measurements of lung function in animal models of pulmonary disease POINT: LUNG IMPEDANCE MEASUREMENTS ARE MORE USEFUL THAN SIMPLER MEASUREMENTS OF LUNG FUNCTION IN ANIMAL MODELS OF PULMONARY DISEASE

Research on pulmonary disease relies increasingly on the use of animal models, commensurate with the progression of our ability to manipulate the genome and recreate noxious environmental conditions in the laboratory. Accordingly, any self-respecting biomedical research institution these days will have set up some kind of advanced animal facility. This costs a huge amount of money and involves ...
