Objectives: Multiple studies have documented the presence of systemic osteopenia in adolescent idiopathic scoliosis and in simulated animal models. Osteopenia was also found to be associated with severe curves and as one of the prognostic factor in predicting curve progression in AIS. The objective of this study was to compare the bone quality and its association with osteopenia between AIS and normal controls.Methods: AIS (n=234) and non-AIS gi...

Objectives: AIS is associated with both low bone mass and elevated serum bone alkaline phosphatase. The greater the latitude of the geographical region, the higher is the prevalence of AIS. These specific features were compatible with the presence of either Vit-D insufficiency or abnormal physiology with Vit-D. It is important to evaluate these potentially treatable conditions regarding their roles in the etiopathogenesis of AIS. The objectives of this case-control study were ...

Introduction: Adolescent idiopathic scoliosis (AIS) is associated with osteopenia, which was found to be a significant prognostic factor for curve progression. However, in-depth quantitative assessment of bone quality was previously hampered by invasive nature of the investigations. The recently available high-resolution pQCT (HR-pQCT) allows a three-dimensional assessment of the bone quality in-vivo. This study aimed to evaluate and compare the bone quality in AIS gi...

Objectives: Vitamin D is essential for bone modeling/remodeling but the relationship between vitamin D status, bone mineral density (BMD) and bone quality parameters remains controversial especially in adolescent population. The aims of this study wase to evaluate the vitamin D status and its correlation with BMD and bone quality parameters among adolescent girls in Hong Kong where information is lacking.Methods: 156 adolescent girls (11–15 years ol...
