DXA evaluation of bone fragility 2 years after bariatric surgery in patients with obesity.

Purpose: The primary objective was to evaluate bone fragility on dual X-ray absorptiometry (DXA) in patients with obesity before and 2 years after bariatric surgery. The secondary objective was to identify risk factors for the development of a bone mineral density ≤ -2 SD at 2 years.

Methods: This descriptive study included patients with obesity who underwent DXA before and 2 years (±6 months) after bariatric surgery.

CT evaluation of bone fragility 2 years after bariatric surgery: an observational study.

Introduction: The objectives were to evaluate bone fragility on computed tomography (CT) in patients with obesity before and 2 years after bariatric surgery and to identify risk factors for a decrease in the scanographic bone attenuation coefficient of the first lumbar vertebra (SBAC-L1).

Materials And Methods: Patients with obesity who underwent bariatric surgery and CT before and 2 years (± 6 months) after bariatric surgery were included. SBAC-L1 was measured on CT with a fracture threshold at 145 HU.

Prevalence of Osteoporosis Assessed by DXA and/or CT in Severe Obese Patients.

The primary objective was to evaluate bone fragility prevalence on dual X-ray absorptiometry (DXA) and computed tomography (CT) in patients with severe obesity. The secondary objective was to evaluate the risk factors for bone fragility. This monocentric study was conducted in patients with grade 2 and 3 obesity.

Relationship between ectopic calcifications and bone fragility depicted on computed tomography scan in 70 patients with systemic sclerosis.

Background: A higher risk of osteoporotic fracture was described in systemic sclerosis patients than in healthy patients.

Objective: To evaluate the relation between osteoporotic fracture risk measured by the scanographic bone attenuation coefficient of the first lumbar vertebra (SBAC-L1) on computed tomography (CT) scan and the presence of ectopic calcifications: vascular, valvular and spinal.

Methods: This monocentric retrospective study was performed on patients followed between 2000 and 2014 at Nancy University Hospital.

Relationship between spinal structural damage on radiography and bone fragility on CT in ankylosing spondylitis patients.

To evaluate whether the risk of bone fragility on computed tomography (CT) (scanographic bone attenuation coefficient of the first lumbar vertebra (SBAC-L1)) is associated with the severity of spine structural involvement (mSASSS) in patients with ankylosing spondylitis (AS). This retrospective study included AS patients, followed from 2009 to 2017, who fulfilled the New York criteria and who underwent thoraco-abdomino-pelvic CT and radiography (spine, pelvis). The structural involvement was retained for mSASSS ≥ 2.
