Using machine learning on new feature sets extracted from 3D models of broken animal bones to classify fragments according to break agent [PDF]
arXiv, 2022 Distinguishing agents of bone modification at paleoanthropological sites is at the root of much of the research directed at understanding early hominin exploitation of large animal resources and the effects those subsistence behaviors had on early hominin evolution.

Determination of Canine Long Bone Ultimate Tensile Strain by Digital Image Correlation [PDF]
, 2022 Creating finite element models for simulation of bone behaviour, fracture occurrence and propagation requires feeding the system with adequate mechanical data. To date, little is known about the mechanical behaviour of long canine bones, and in cases of modelling a bone-breakage scenario the ultimate strain at failure still needs to be determined ...

FRACTURES OF THE NASAL BONES. [PDF]
JAMA: The Journal of the American Medical Association, 1898 Neither in the works on surgery, nor in the special works on the nose and throat is there much information about this subject, and yet any injury deflecting the nasal bones causes a deformity very apparent and disagreeable throughout life, besides often obstructing one of the nostrils.

Alzheimer’s disease and its associated risk of bone fractures: a narrative review
Frontiers in Endocrinology, 2023 BackgroundAlzheimer’s disease (AD) is a neurodegenerative disorder that is the major cause of dementia in the aged population. Recent researches indicate that patients with AD have a significantly increased fracture risk, but the pathological mechanisms ...

Numerical investigation into fracture resistance of bone following adaptation [PDF]
arXiv, 2020 Bone adapts in response to its mechanical environment. This evolution of bone density is one of the most important mechanisms for developing fracture resistance. A finite element framework for simulating bone adaptation, commonly called bone remodelling, is presented.

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Does Superior Bone Health Promote a Longer Lifespan?
Geriatric Orthopaedic Surgery & Rehabilitation, 2021 Introduction Public health achievements throughout the last century have resulted in a steady increase in life expectancy. An emergent subset has distinguished themselves, living well beyond the ninth decade by avoiding or delaying the onset of most age ...

Arthritis Care &Research, EarlyView.Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.
