Assessment of mandibular growth potential is an essential component of proper diagnosis and treatment planning in orthodontics. The aim of this study was to evaluate the possibility of utilizing the cervical vertebral bone age method to predict the mandibular growth potential in a group of growing Saudi individuals. The sample consisted of the lateral cephalometric radiographs of untreated 84 S...

In view of the interactions of vitamin D and the estrogen endocrine system, we studied the combined influence of polymorphisms in the estrogen receptor (ER) alpha gene and the vitamin D receptor (VDR) gene on the susceptibility to osteoporotic vertebral fractures in 634 women aged 55 yr and older. Three VDR haplotypes (1, 2, and 3) of the BsmI, ApaI, and TaqI restriction fragment length polymor...

A finite element model of the T12-L1 motion segment was subjected to dynamic vertical impact to investigate vertebral burst fracture mechanism at the thoracolumbar junction. A rigid ball was directed vertically towards a rigid plate fixed on top of the T12 vertebral body to simulate the axial impact. The results show that upon impact, the T12 vertebra exhibited a vibratory motion. At its maximu...

BACKGROUND Severely disabled children with cerebral palsy (CP) are prone to low trauma fractures, which are associated with reduced bone mineral density. AIMS To determine whether participation in 50% longer periods of standing (in either upright or semi-prone standing frames) would lead to an increase in the vertebral and proximal tibial volumetric trabecular bone mineral density (vTBMD) of ...

Microarchitecture of trabecular bone is a very important component of bone quality in osteoporosis and a determinant of vertebral fracture in men with low bone mineral density (BMD). In contrast to women, male osteoporosis is, in most cases, secondary. The relationships between microarchitecture and different risk factors have never been evaluated in men. About 152 men with low BMD at the lumba...

A 27-year-old male presented with a very rare metastasis to the vertebral body from a cardiac pheochromocytoma manifesting as a pathological fracture of the C-4 vertebral body that occurred while playing golf. The patient was initially treated with hard collar fixation. Gallium scintigraphy demonstrated multiple hot spots in the mediastinum, the frontal bone, the vertebral column, and the rib. ...

BACKGROUND Stereotactic body radiation therapy (SBRT) is a radiation technique used in patients with oligometastatic lung disease. Lung and chest wall toxicities have been described in the patients but pathological vertebral fracture is an adverse effect no reported in patients treated with SBRT for lung metastases. CASE PRESENTATION A 68-year-old woman with the diagnosis of a recurrence of a...

Osteoporosis is a characterized by low bone mass and microarchitectural deterioration, with a consequent increase in bone fragility [1]. Bone strength impairment leads to an increased risk of fracture, as strenght reflects the integration of bone quantity (bone mineral density, BMD) and bone quality [2]. Common sites of osteoporotic fractures are spine, hip, distal forearm and proximal homerus....

BACKGROUND Bone is a frequent site of metastases in advanced cancer and is associated with significant skeletal morbidity. Current treatment options are aimed at preserving and improving functional independence and quality of life. MATERIALS AND METHODS A review of current literature focusing on diagnostic tools and treatment approaches of bone metastasis in advanced cancer was performed and ...

BACKGROUND Vascular calcifications and the bone fractures caused by abnormal bone fragility, also called osteoporotic fractures, are frequent complications associated with chronic kidney diseases (CKD). The aim of this study was to investigate the association between vascular calcifications, osteoporotic bone fractures and survival in haemodialysis (HD) patients. METHODS A total of 193 HD pat...
