From: Preoperative dual-energy X-ray absorptiometry and FRAX in patients with lumbar spinal stenosis
Percentage of patients classified as having osteoporosis, osteopenia, or normal bone quality in a women with LSS (n = 37), b men with LSS (n = 28), c women with HOA (n = 33), and d men with HOA (n = 20). The T-score was based on DXA measurements in four different/projections: lumbar spine anterior-posterior (AP), lateral spine (lateral), lateral-mid spine (lateral mid), and the femoral neck (FN). Osteoporosis: T-score ≤ − 2.5; osteopenia: − 1 > T-score > − 2.5; and normal: T-score ≥ − 1
