DEXA/ BMD
Case 1
Indication: History of fracture
?Osteoporosis
60yr old female presents with left neck of femur fracture after simple fall from standing height,treated with hip replacement. There is no history of other previous fractures or risk factors for Osteoporosis.
BMD shows Osteopenia (i.e. T score -1.0 to -2.5) at the right neck of femur & lumbar spine (L1-L4). She can be diagnosed with established Osteoporosis with minimal trauma fracture (despite BMD not in the Osteoporotic range). She has a high risk of further fractures and qualifies for Osteoporosis medication. Repeat BMD measurement in 2yrs recommended.
Case 2
Indication: Screening age > 70
?Osteoporosis
72 yrold male with no history of fracture, has risk factors for Osteoporosis (excess alcohol, smoking, VitaminD deficiency and family h/o Osteoporosis), referred for BMD to screen for Osteoporosis.
BMD shows Osteoporosis (T score < -2.5) at the left neck of femur & lumbar spine (L1-L4). With the low bone density, this patient has a high risk of fracture and qualifies for Osteoporosis medication (such as biphosphonates) to reduce the risk of fracture. Repeat BMD measurement in 1yr to monitor change in therapy recommended.
