Preoperative dual-energy X-ray absorptiometry and FRAX in patients with lumbar spinal stenosis

Table 6 FRAX assessment in LSS patients

Evaluation of the risk of having an osteoporotic fracture within 10 years, using FRAX alone or FRAX with FN BMD and subdivided according to FN T-score. The patients (n = 65) were divided into two different groups: T-score in the lateral projection ≤ − 2.5 and T-score in the lateral projection > − 2.5, measured in at least one vertebra. Moderate to high risk (> 10% risk) and low risk (≤ 10% risk) of having an osteoporotic fracture within 10 years
