Semi-quantitative grading and extended semi-quantitative grading for osteoporotic vertebral deformity: a radiographic image database for education and calibration.

Ann Transl Med 2020 Mar;8(6):398

Department of Radiology, Hospital of Traumatology, Carretera de Jaen SN, Granada, Spain.

The Genant's semi-quantitative (GSQ) criteria is currently the most used approach in epidemiology studies and clinical trials for osteoporotic vertebral deformity (OVD) evaluation with radiograph. The qualitative diagnosis with radiological knowledge helps to minimize false positive readings. However, unless there is a face-to-face training with experienced readers, it can be difficult to apply GSQ criteria by only reading the text description of Genant (in 1993), even for a musculoskeletal radiologist.

Height of overburden fracture based on key strata theory in longwall face.

PLoS One 2020 24;15(1):e0228264. Epub 2020 Jan 24.

School of Minerals and Energy Resources Engineering, Faculty of Engineering, University of New South Wales, Sydney NSW, Australia.

Among the three overburden zones (the caving zone, the fracture zone, and the continuous deformation zone) in longwall coal mining, the continuous deformation zone is often considered to be continuous without cracks, so continuum mechanics can be used to calculate the subsidence of overburden strata. Longwall coal mining, however, will induce the generation of wide cracks in the surface and thus may cause the continuous deformation zone to fracture. In this paper, whether there are cracks in the continuous deformation zone as well as the height of overburden fracture in longwall face and the subsidence and deformation of strata of different fracture penetration ratios were studied by means of physical simulation, theoretical analysis and numerical simulation.

A high-fidelity 3D S-FEM stress analysis of a highly heterogeneous swine skull.

Med Biol Eng Comput 2020 Mar 14;58(3):625-641. Epub 2020 Jan 14.

School of Mechanical Engineering, Hebei University of Technology, Tianjin, 300401, China.

Fracture healing and growth of the bones are highly related to the stress level. Numerical analysis of stresses is the most effective means to determine the stress level, but it usually requires sufficient resolution to ensure an accurate description of geometry features of bones. In this paper, high-fidelity smoothed finite element method (S-FEM) skull models are created using computed tomography (CT) and micro-computed tomography (μCT) images of a juvenile pig skull.

Histological evaluation of the acetabular labrum after bipolar hip hemiarthroplasty: a case report.

Med Mol Morphol 2020 Jan 13. Epub 2020 Jan 13.

Department of Orthopaedic Surgery, Faculty of Medicine, Oita University, 1-1 Idaigaoka Hazama-machi, Yufu City, Oita, 879-5593, Japan.

We report herein the microstructure of the acetabular labrum obtained from a patient with stem loosening but without bipolar cup migration who had undergone hemiarthroplasty for femoral neck fracture 18 years ago. We used light and scanning electron microscopy to investigate the influence of bipolar cup on acetabular labrum in vivo. Deparaffinized blocks were treated with 2 N NaOH to digest the cell matrix, allowing the collagen fibers, constituting the acetabular labrum, to be observed under scanning electron microscopy.

A Study on the Potential Role of Occlusal Fissure Fractures in the Etiopathogenesis of Equine Cheek Teeth Apical Infections.

J Vet Dent 2019 Sep;36(3):171-178

Department of Clinical Veterinary Studies, Royal (Dick) School of Veterinary Studies and Roslin Institute, The University of Edinburgh, Easter Bush Veterinary Centre, Midlothian, EH25 9RG, Scotland, United Kingdom.

Thirty-nine equine cheek teeth diagnosed as having anachoretic apical infections and also having occlusal fissure fractures, but without occlusal pulpar exposure, that had been orally extracted without causing occlusal damage and 10 control teeth were used in this study. The teeth were individually imaged by computed tomography, occlusally stained with methylene blue and visually reexamined, then sectioned subocclusally at 5 mm intervals until the fissure fractures could no longer be detected. A limited histological study was then performed on 7 apically infected and 5 control teeth. Read More

Neuromuscular Diseases and Bone.

Front Endocrinol (Lausanne) 2019 22;10:794. Epub 2019 Nov 22.

Department of Medical and Surgical Specialties and Dentistry, University of Campania "Luigi Vanvitelli", Naples, Italy.

Neuromuscular diseases (NMDs) are inherited or acquired conditions affecting skeletal muscles, motor nerves, or neuromuscular junctions. Most of them are characterized by a progressive damage of muscle fibers with reduced muscle strength, disability, and poor health-related quality of life of affected patients. In this scenario, skeletal health is usually compromised as a consequence of modified bone-muscle cross-talk including biomechanical and bio-humoral issues, resulting in increased risk of bone fragility and fractures.
