CausesAppropriate Tests

Clinical assessment, including age, gender, presence of systemic disease.

See also Bone fracture - pathological.

Generalised

Investigation may be appropriate to demonstrate increased bone loss prior to the development of clinical disease in high risk patients; to establish the diagnosis of osteoporosis; to monitor efficacy of treatment.

Investigation may include bone density measurement and diagnostic imaging; calcium, phosphate, albumin, vitamin D, ALP; urine - calcium, creatinine, collagen crosslink fragments or hydroxyproline with hydroxyproline/creatinine ratio.

Collagen crosslink fragments are more specific for bone resorption than hydroxyproline.

Bone loss commences prior to the menopause.
