Endocortical bone loss in osteoporosis: The role of bone surface availability [PDF]

open access: yesInt J Numer Meth Biomed Engng (2013) 29:1307-1322, 2012
Age-related bone loss and postmenopausal osteoporosis are disorders of bone remodelling, in which less bone is reformed than resorbed. Yet, this dysregulation of bone remodelling does not occur equally in all bone regions. Loss of bone is more pronounced near and at the endocortex, leading to cortical wall thinning and medullary cavity expansion, a ...

Biomechanics and mechanobiology of trabecular bone: a review.

open access: yesJournal of Biomechanical Engineering, 2015
Trabecular bone is a highly porous, heterogeneous, and anisotropic material which can be found at the epiphyses of long bones and in the vertebral bodies.

THE CLINICAL SIGNIFICANCE OF THE ULNAR NUTRIENT FORAMEN: A MORPHOLOGICAL ANALYSIS.

open access: yesStudent's Journal of Health Research Africa, 2023
Background: The arteries that provide nutrients to the bone enter the bone of the ulna through the nutrient foramina. During bone grafting, it is necessary to understand the position and number of nutrient foramina to ensure that the bone grafts have a ...

Modelling the anabolic response of bone using a cell population model [PDF]

open access: yesJ Theor Biol 307 (2012) 42-52, 2011
To maintain bone mass during bone remodelling, coupling is required between bone resorption and bone formation. This coordination is achieved by a network of autocrine and paracrine signalling molecules between cells of the osteoclast lineage and cells of the osteoblastic lineage.

Osseointegrated titanium implants. Requirements for ensuring a long-lasting, direct bone-to-implant anchorage in man.

open access: yesActa Orthopaedica Scandinavica, 1981
A total of 2895 threaded, cylindrical titanium implants have been inserted into the mandible or the maxilla and 124 similar implants have been installed in the tibial, temporal or iliac bones in man for various bone restorative procedures.

Breast Cancer Induced Bone Osteolysis Prediction Using Temporal Variational Auto-Encoders [PDF]

open access: yesarXiv, 2022
Objective and Impact Statement. We adopt a deep learning model for bone osteolysis prediction on computed tomography (CT) images of murine breast cancer bone metastases. Given the bone CT scans at previous time steps, the model incorporates the bone-cancer interactions learned from the sequential images and generates future CT images.

Bone phenotypes in rheumatology – there is more to bone than just bone [PDF]

open access: yesBMC Musculoskeletal Disorders, 2020
AbstractOsteoarthritis, rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, all have one clear common denominator; an altered turnover of bone. However, this may be more complex than a simple change in bone matrix and mineral turnover.

Observation of Mammalian Similarity Through Allometric Scaling Laws [PDF]

open access: yes, 2002
We discuss the problem of observation of natural similarity in skeletal evolution of terrestrial mammals. Analysis is given by means of testing of the power scaling laws established in long bone allometry, which describe development of bones (of length ...

Ionizing radiation effects on osseointegration: a pre-clinical study [PDF]

open access: yesBrazilian Oral Research
The purpose of this study was to evaluate the effect of a single dose of ionizing radiation (30 Gy) on the osseointegration of implants in the rabbit tibia. Twenty rabbits received two dental Morse-tapered junction implants and one implant in each tibia.
