clinical indications for bone densitometry
- a patient with a history of a low trauma fracture e.g. spine, hip, distal forearm
- an incidental X-ray finding of osteopenia or vertebral collapse or in the investigation of thoracic kyphosis or loss of height
- if there is maternal history of hip fracture
- if the patient has a low body mass index (BMI < 19 kg/m^2)
- if the patient has received corticosteroid treatment (prednisolone 7.5 mg or more) for greater than three months
- oestrogen deficiency:
- in a patient with premature menopause (< 45 years of age)
- primary hypogonadism
- secondary amenorrhoea (which lasts more than six months) e.g. secondary to GnRH anologues
- where there are conditions that predispose to secondary osteoporosis including:
- malabsorption syndromes e.g. coeliac disease, inflammatory bowel disease
- long-term treatment with anticonvulsants
- organ transplantation
- eating disorders
- chronic renal failure
- primary hyperparathyroidism
- Cushing's syndrome
- male hypogonadism
- prolonged immobilisation
Therefore it is inappropriate to scan premenopausal women without any additional risk factors apart from a family history of osteoporosis or patients with back pain unless there is X-ray evidence of a recent vertebral crush fracture (1).
