Abstract Introduction Spine and hip bone mineral density (BMD) have previously been shown to predict the risk of sustaining future fractures. Although these have been shown in population studies, there is a paucity of trials looking at the relationship between BMD and 10 year probability of major osteoporotic fractures (Using FRAX UK without BMD) in patients with previous fragility fractures. Aims To evaluate the correlation between spinal T-score and an absolute 10 year probability of sustaining a major osteoporotic fracture (using FRAX without BMD) in patients with prior fragility fractures. Methods A retrospective cross-sectional analysis of 202 patients (29 males and 173 females) with prior fragility fractures attending a fracture prevention clinic between January and August 2019 was performed. Patients with pathological and high impact traumatic fractures were excluded. The BMD at the spine was determined using the lowest T-score of the vertebrae from L1 to L4. Using the FRAX (UK) without BMD, the absolute 10 year probability of sustaining a major osteoporotic fracture was calculated for each patient. Statistical analysis was performed using SPSS 26 software. Results The mean T-score at the spine was −1.15 (SD +/− 1.90) for all patients, −0.68 (SD +/− 0.45) for males and − 1.23 (SD +/− 0.14) for females. The mean FRAX score without BMD for major osteoporotic fracture was 18.5% (SD +/− 8.84) for all patients, 11.41% (SD +/−0.62) and 19.7% (SD +/−0.68) for males and females respectively. Pearson correlation coefficient showed a statistically significant, slightly negative correlation between spinal T- score and the FRAX (UK) without BMD (r = −0.157; p < 0.05). Correlation was not statistically significant when males (r = 0.109; p = 0.59) and females (r = 0.148; p = 0.053) were considered independently. Conclusion In patients with prior fragility fracture spinal BMD has a statistically significant negative correlation with an absolute 10 year probability of sustaining a major osteoporotic fracture.

<span>Osteoporosis is a systemic skeletal disease. Parameter from any bone site in the body has possibility to be developed as a predictor of osteoporosis. The alteration in the mandible trabecular bone is visible in periapical radiographs. The aim of this study was to correlate the area parameter and the integrated density of periapical radiograph with bone mineral density. Image analysis of periapical radiograph i.e. measurement of area parameter and integrated density was done on Region of Interest (ROI) by using canny edge detection method. Result of this study showed that the area parameter has asignificant (α&lt;0.05) negative correlation with the bone mass density (BMD) of the lumbar spine (r = -0.371) and T-score of the lumbar spine (r = -0.383). The linear regression test showed that the area parameter only can be used to predict T-score of the lumbar spine (F=5.822, α&lt;0.05). The integrated density showed a significant (α &lt; 0.05) negative correlation with T-score of hip (r = -0.332) and T-score of lumbar spine (r = -0.377). It can be concluded that the area parameter can be used as one of input parameters for computer-aided system of osteoporosis early detection by using periapical radiograph.</span>

Introduction. Osteoporosis is a metabolic skeletal disease characterized by bone mineral density reduction, which may lead to an increased risk of bone fractures. Obesity is a condition of excessive body fat that causes or aggravates many public health problems. As it is easy to be measured, body mass index is widely used as an index of the degree of obesity. Material and Methods. The study included 1.372 female orthopedic patients between the ages of 30 to 79 years who visited the Clinical Centre of Vojvodina in Novi Sad to have a dual-energy x-ray absorptiometry (DEXA) examination in the period from March, 2010 to June, 2013. The following anthropometric data were collected: body mass index, body weight, height, dual-energy x-ray absorptiometry T-score and bone mineral density (BMD), as well as some other data. Results. The mean age was 62.08 years, the mean weight was 73.59 kg and the mean height was 1.6 m. There were 392 participants in the group of normal body mass index, 14 participants were underweight, and 966 were overweight and obese. In the overweight and obese group, 25.25% participants had osteoporosis, 35.4% had osteopenia and 39.33% had the normal T-score. In the normal body mass index group, 42.34% of the participants had osteoporosis, 29.3% had osteopenia and 28.31 had the normal T-score. In the underweight group, 57.14% of the participants had osteoporosis, 21.42% had osteopenia and 21.42% had the normal T-score. Conclusion. No strong correlation between body mass index and bone mineral density was found in our study, but it is obvious that there was a stronger correlation between body mass index and bone mineral density of the total hip than between body mass index and bone mineral density of the lumbar spine.

Abstract Abstract 4989 Background: Bone disease is present at diagnosis in almost all patients with multiple myeloma (MM) and can impact substantially on patient morbidity and quality of life. Decreased bone mineral density is also observed not only in MM but also in patients with monoclonal gammopathy of undetermined significance (MGUS). The pathogenesis of bone disease in MM is complex. The activity of proteasome inhibitor bortezomib has been linked to increased bone formation and osteoblastic activation. Evidence from the available clinical data indicates that bortezomib has a positive impact on bone health in MM and demonstrates a bone anabolic effect. Methods: We analyzed retrospectively 53 patients with MM and 16 with MGUS who have completed bone density at least at diagnosis. 21 patients have completed two bone density (3 MGUS and 18 MM). The bone density was obtained in all patients at baseline and in 16 patients repeated after bortezomib treatement with a median time of bortezomib exposure of 6 months. We analyzed T-score values at lumbar spine and at femoral neck. Results: With a median age of 66 years, 41 male and 28 female were analyzed. At baseline the mean lumbar spine T-score of all subjects and of 16 MM treated with bortezomib was -0.50 and -0.76 respectively. At baseline the mean femoral neck T-score for all subjects and for 16 MM treated with Bortezomib was -1.56 and -1.31 respectively. The baseline mean lumbar spine T-score for MGUS and MM was -0.71 and -0.43 respectively. The baseline mean femoral neck T-score of MGUS and MM was -1.61 and -1.54 respectively. In the group of 16 patients treated with Bortezomib we observed from baseline a change in lumbar bone mineral density T-score of 0.36 and at femoral neck bone density T-score of 0.25. Conclusion: These data show that patients treated with proteasome inhibitor showed moderate increment in bone mineral density at lumbar spine and at femoral neck.
