Our objective was to determine the prevalence, the shape of vertebral fractures in a population with primary hyperparathyroidism with slot scanning system. Asecondary goal was to know the reliability of assessment of vertebral fractures in this population and their consequences A tertiary goal was to compare characteristics of patients with and without fracture

All patients were included consecutively and prospectively in our institution. They were suspected of primary hyperparathyroidism. They had Full Spine acquisition (AP and lateral views) with slot scanning system EOS. Two musculoskeletal radiologists (one senior and one resident)assessed location, number, shape and Genant grade of lumbar and dorsal vertebral fractures. They assessed sagittal balance parametersusing "Posture assessment" Workflow in SterEOS Software (Fig 1). We assessed reliability of qualitative and quantitative measurements and we compared clinical and radiological parameters for patients with or without fractures. We...

41patients were included:39 women (95.1%) and2 men (4.9%). Average age was 68 (+/- 9). Average height was 159 cm (+/- 6.6). Average weight was 60.7 kg (+/- 14). Average Body Mass Index was 23.97 kg/m2 (+/- 5.1). Average decrease in size was 4.17 cm (+/- 2.44). Average Bone Mineral Density (BMD) in Lumbar Spine was 0.791 g/cm2 (+/- 0.22) i.e average T-score of -2.34 (+/-1.69). Average femoral neck BMD was 0.633 g/cm2 (+/- 0.10) i.e average T-score of -2.28 (+/- 0.93). 10 patients (24.4%) had...

Slot scanning system EOS ® is a easy tool to depict vertebral fractures for patients with primary hyperparathyroidism, which are often non-painful. It allows, in addition,assessment of sagittal balance parameters.
