Bone mineral density (BMD) measured with dual-energy X-ray absorptiometry (DXA) is widely used in clinical practice to assess fracture risk and guide management. DXA can also assess hip geometry, including femoral neck width (FNW) and hip axis length (HAL), which have both been associated with increased risk for hip fracture independently from BMD. Our objective was to assess if FNW predicts hip fracture independently from other factors including HAL.

Immune checkpoint inhibitors (ICI) are widely used in cancer treatment, yet their impact on bone health remains unclear. This study aimed to perform a retrospective cohort study utilizing routine computed tomography (CT) scans from patients with melanoma to perform opportunistic quantitative CT (QCT) analysis to investigate the effects of ICI treatment on skeletal health, including volumetric bone mineral density (vBMD) measurements and osteoarthritis (OA) parameters. A previously established machine-learning assisted opportunistic QCT pipeline was used to estimate lumbar spine vBMD from baseline and 12-month follow-up CT scans in patients with melanoma treated with ICI therapy and those not treated with ICI therapy.

Context: There are limited real-world data evidence assessing the clinical characteristics of hospitalized osteoporotic fractures in China.

Objective: To investigate the clinical characteristics of hospitalized major osteoporotic fractures in Northeast China.

Methods: We identified hospitalized fracture patients aged 50 and over from the First Affiliated Hospital of Jinzhou Medical University between January 1, 2018, and December 31, 2022.

Radiologists and other diagnostic imaging specialists play a pivotal role in the management of osteoporosis, a highly prevalent condition of reduced bone strength and increased fracture risk. Bone mineral density (BMD) measurement with dual-energy X-ray absorptiometry (DXA) is a critical component of identifying individuals at high risk for fracture. Strategies to prevent fractures are consolidated in the Osteoporosis Canada clinical practice guideline which was updated in 2023.

Vertebral fracture assessment (VFA) images from bone density machines enable the automated machine learning assessment of abdominal aortic calcification (ML-AAC), a marker of cardiovascular disease (CVD) risk. The objective of this study was to describe the risk of a major adverse cardiovascular event (MACE, from linked health records) in patients attending routine bone mineral density (BMD) testing and meeting specific criteria based on age, BMD, height loss, or glucocorticoid use have a VFA in the Manitoba Bone Mineral Density Registry. The cohort included 10 250 individuals (mean 75.
