TBS improves the detection of subjects at risk of fracture irrespectively to the BMD status: a Spanish population-based study

Gregorio Silvana Di , Winzenrieth Renaud , Rio Luis Del

Iisn’t uncommon to encounter patients with both a fragility fracture and only a slightly low BMD value or even normal one. Currently the DXA technology can assess information on trabecular microstructural texture supplementing the standard BMD measurement, using a new method: the trabecular bone score (TBS). In order to check TBS, BMD and their combination to discriminate patients with vertebral fracture, we scanned 946 subjects. The cohort was stratified using the WHO di...

Bone mass, bone microarchitecture and anthropometric measurements during childhood growth in Spanish girls

Rio Luis Del , Winzenrieth Renaud , Cormier Catherine , DiGregorio Silvana

The aim of the present study was to evaluate bone mass and bone microarchitectural texture as assessed by trabecular bone score (TBS) modification at spine during childhood growth in girls.The study group was composed of 415 healthy girls aged between 2 and 17 years old. Height, weight and BMI Z-scores were evaluated and compared to The WHO Child Growth Standards. Pubertal stage was evaluated using Tanner score. The areal BMD (aBMD) was assessed...

Influence of age and gender on spine bone density and TBS microarchitectural texture parameters in infants

Winzenrieth Renaud , Cormier Catherine , DiGregorio Silvana , Rio Luis Del

Children bone knowledge is relatively sparse. This is especially true for infant and for bone microarchitecture data. We have investigated, in this study, the age-related modifications of spine microarchitectural texture, as assessed by TBS, on male and female infants during their two first years of life.The study group was composed of 143 and 109 healthy female and male infants aged between 0 and 2 years. Height and weight Z-scores were signifi...

Combination of spine TBS and clinical risk factors (CRF) can be used to detect women with osteoporotic fracture: a US study

Leib Edward , Lamy Olivier , Winzenrieth Renaud , Hans Didier

BMD alone is not sufficient to predict the fracture risk for an individual. Others parameters, such as microarchitecture play a key role in bone fragility. Several cross-sectional studies have shown the ability of TBS to discriminate fractured from healthy subjects in European populations. The aim of our study is to assess the ability of TBS, evaluated at the lumbar spine, to discriminate subjects with and without fracture in a large white US population....

Bone quality and quantity in Duchenne Muscular Dystrophy patients

Del Rio Luis , Winzenrieth Renaud , Di Gregorio Silvana

The aim of the study is to evaluate bone quantity (aBMD) and bone quality as assessed by TBS in DMD subjects.43 boys and girls suffering from DMD with a mean age 10.5±3.7 years and height and weight z-score (Zc) medians of −0.67 and 0.25 S.D. were included in the study. Spine DXA scans were obtained using a GE Lunar iDXA with software v13.31. Lumbar spine trabecular bone texture (TBS) was determined using Med-Imaps cust...

Evolution of bone quality and quantity in patients suffering from Duchenne Muscular Dystrophy

Del Rio Luis , Di Gregorio Silvana , Winzenrieth Renaud

The aim of the study is to evaluate, across time, if a bone microarchitectural texture modification exists or not and to evaluate its associations with other bone and body composition parameters.16 Spanish children suffering from DMD with a mean age 9.7±3.0 years and height and weight z-score of −0.76 and 0.16 SD were included in the study. Spine DXA scans and body composition scans were obtained using a GE Lunar Prodigy at baseline, ...

The role of bone age in the evaluation of trabecular bone score (TBS) of children and adolescents 5--19 years old

Guagnelli Miguel Angel , Ambrosi Regina , Lopez-Gonzalez Desiree , Winzenrieth Renaud , Del Rio Luis , Clark Patricia

Rationale: Trabecular Bone Score (TBS) is a texture-based tool analyzing DXA images in order to assess bone microarchitecture in the lumbar region. In pediatric population, definition of normative values has remained elusive due to the disparities of results in normal population, probably link to uncontrolled factors which impact bone microarchitecture and the nonlinear behavior of bone growth. Our objective was to evaluate TBS in healthy Mexican children and adolescents using...
