Composition and characteristics of trabecular bone in osteoporosis and osteoarthritis.

Background: Bone strength depends on multiple factors such as bone density, architecture and composition turnover. However, the role these factors play in osteoporotic fractures is not well understood.

Purpose: The aim of this study was to analyze trabecular bone architecture, and its crystal and organic composition in humans, by comparing samples taken from patients who had a hip fracture (HF) and individuals with hip osteoarthritis (HOA).

Age related changes in the bone microstructure in patients with femoral neck fractures.

Background: The risk of femoral neck fracture progressively increases with age. However, the reasons behind this consistent increase in the fracture risk can't be completely justified by the decrease in the bone mineral density. The objective of this study was to analyze the correlation between various bone structural features and age.

Sleep-Disordered Breathing Is Associated with Reduced Mandibular Cortical Width in Children.

Introduction: Evidence from the adult population suggests that sleep-disordered breathing (SDB) (i.e., obstructive sleep apnea [OSA]) is negatively associated with bone mineral density.

Genotype and malocclusion in patients with osteogenesis imperfecta.

Objects: To investigate the relationship between genotype and severity of malocclusion in osteogenesis imperfecta (OI).

Setting And Sample Population: A total of 49 patients participated in this cross-sectional study (age range: 5-19 years; 28 females; diagnoses: OI type I, N = 7; OI type III, N = 11; OI type IV, N = 27; OI type V, N = 2; OI type VI, N = 2).

Materials And Methods: Sequence analysis of COL1A1/COL1A2 and other OI-related genes was compared to the Peer Assessment Rating (PAR), an index reflecting the severity of malocclusion.
