We report a 38-year-old male with a nonunion followed by plate breakage after volar plating of a distal radius osteotomy. Volar locking plates have added a new approach to the treatment of distal radius malunions, due to a lower morbidity of the surgical approach and the strength of the final construction, allowing early mobilization and return to function. Conclusion. Plate breakage is an unco...

OBJECTIVE Reduced bone mineral density (BMD), assessed by Dual Energy X-ray absorptiometry (DXA), is a well-known risk factor for fragility fracture. A large proportion of patients with fracture have only slightly reduced BMD. Assessment of other bone structure features than BMD may improve identification of individuals at increased fracture risk. Digital X-ray radiogrammetry (DXR), which is a ...

BACKGROUND Bone loss increases after menopause. However, bone strength also depends on structural characteristics such as bone size. Whether bone size increases as a result of periosteal apposition and whether a strength index accounting for both bone density and bone size might predict the risk of fracture better than bone density alone are unclear. METHODS Bone mass and the skeletal structu...

As tetrapods increase in size and weight through ontogeny, the limb skeleton must grow to accommodate the increases in body weight and the resulting locomotor forces placed upon the limbs. No study to date, however, has examined how morphological changes in the limb skeleton during growth reflect ontogenetic patterns of limb loading and the resulting stresses and strains produced in the limbs. ...

PURPOSE Low bone mass is a major health concern among young women nowadays due to sedentary lifestyle and lack of calcium rich food intake. Therefore there is an increase in the incidence of LBM among young university women so our main purpose of study was to compare effects of exercise program and calcium supplements on bone mass in young women. METHODS This single blinded, cross sectional s...

Context The maternal heritability of bone microarchitecture according to the sex of the offspring is not known. Objective To explore sex difference and influence of mother's menopausal status on the heritability of bone microarchitecture between mothers and their offspring. Subjects and Methods In 102 mother-daughter and 161 mother-son pairs, volumetric bone mineral density (BMD) and bone m...

The maintenance of bone strength has been an important issue in the debate over cage use for laying hens. Bone strength depends on adequate mechanical load and cages restrict movement. Four laying crosses (Lohmann White, Lohmann Brown, H&N White, and Rhode Island Red × Barred Plymouth Rock cross hens) were housed in conventional cages or in floor pens equipped with perches and nest boxes to mea...

BACKGROUND The relative importance of body composition, lifestyle factors, bone turnover and hormonal factors in determining bone mineral density (BMD) is unknown. We studied younger postmenopausal women to determine whether modifiable or nonmodifiable risk factors for osteoporosis have stronger associations with BMD. METHODS In multivariable linear regression models, we tested associations b...

OBJECTIVE To determine the effect of thiazide diuretic drugs on rates of bone mineral loss. DESIGN Longitudinal, observational study with a mean follow up of five years. SETTING Hawaii Osteoporosis Center, Honolulu. SUBJECTS 1017 Japanese-American men born between 1900 and 1920, of whom 378 were treated for hypertension (study group) and 639 did not have hypertension (control group). IN...

Although single-photon absorptiometry (SPA) has been the predominant tool used to assess bone mineral density (BMD) in the forearm, the development of dual-energy x-ray absorptiometry (DEXA) provides the benefits of greater source stability, reduced scanning time, and improved image resolution compared to SPA. In the present study we used the DEXA bone densitometer (Hologic, Inc., Waltham, MA) ...
