A case report of an unrecognized osteoid osteoma of the proximal femur
Radiology Case Reports, 2020 We present the case of a 59-year-old male patient with unrecognized osteoid osteoma in radiography as well as in magnetic resonance imaging. Computed tomography revealed osteoid osteoma that was successfully treated with percutaneous computed tomography ...

The British Journal of Radiology, 1989 Abstract Although the typical features of osteoid osteomas are well known, those arising in phalanges are frequently misdiagnosed. This is partly because of their rarity (9% of osteoid osteomas in the Bristol Bone Tumour Registry occur in phalanges), and also because of atypical radiological features.

Advanced Science, EarlyView.This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Osteocytes as a record of bone formation dynamics: A mathematical model of osteocyte generation in bone matrix [PDF]
, 2014 The formation of new bone involves both the deposition of bone matrix, and the formation of a network of cells embedded within the bone matrix, called osteocytes.

Animal Models and Experimental Medicine, EarlyView.This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Acta orthopaedica Belgica, 2006 Osteoid osteoma is a relatively frequent benign bone tumour, consisting of osteoid and woven bone, and surrounded by a halo of reactive sclerotic bone, with an average size of the nidus less than 1.5 cm. It is a condition of late childhood, adolescence and young adult age.
