The influence of bone surface availability in bone remodelling - A mathematical model including coupled geometrical and biomechanical regulations of bone cells [PDF]
Eng Struct (2013) 47:134-147, 2012 Bone is a biomaterial undergoing continuous renewal. The renewal process is known as bone remodelling and is operated by bone-resorbing cells (osteoclasts) and bone-forming cells (osteoblasts). Both biochemical and biomechanical regulatory mechanisms have been identified in the interaction between osteoclasts and osteoblasts.

Intra-articular osteoid osteoma of tempromandibular joint: A rare entity
Journal of Dr. NTR University of Health Sciences, 2021 Osteoid osteomas are benign neoplasms of bone that generally manifests in the long bones. Intra-articular osteoid stoma of tempromandibular joint is a rare manifestation. We report a rare case of osteoid osteoma of the mandibular condyle encompassing the

Foot Bone in Vivo: Its Center of Mass and Centroid of Shape [PDF]
PLoS ONE. 2011, 6(12): e28868, 2010 This paper studies foot bone geometrical shape and its mass distribution and establishes an assessment method of bone strength. Using spiral CT scanning, with an accuracy of sub-millimeter, we analyze the data of 384 pieces of foot bones in vivo and investigate the relationship between the bone's external shape and internal structure.

Concurrent consideration of cortical and cancellous bone within continuum bone remodelling [PDF]
, 2020 Continuum bone remodelling is an important tool for predicting the effects of mechanical stimuli on bone density evolution. While the modelling of only cancellous bone is considered in many studies based on continuum bone remodelling, this work presents an approach of modelling also cortical bone and the interaction of both bone types.
