Recommended
biochemical tests for patients being assessed for osteoporosis as per
the 2010 OC Guidelines: serum calcium corrected for albumin or ionized
calcium, complete blood count (CBC), creatinine or eGFR, alkaline
phosphatase, thyroid stimulating hormone (TSH). For patients with
vertebral fractures, a serum protein electrophoresis is also
recommended. Vitamin D (25-hydroxy vitamin D) should be measured after
3-4 months of adequate supplementation and should not be repeated if
optimal level ≥ 75 nmol/L is achieved.
The
IOF Best Practice Framework indicates that patients with any fragility
fracture should be assessed for the presence of spine fractures. This
requires a lateral view of the thoracic and lumbar spine, typically by
conventional x-rays or, where available, by Vertebral Fracture
Assessment (VFA) by DXA. If the initial presenting fracture is a
vertebral fracture, it is important to ensure that the entire spine is
imaged (e.g. if a T10 fracture is identified on a lateral chest x-ray,
then a lateral view of the lumbar spine is also indicated).
Adequate
vitamin D supplementation
is important, not only for bone health, but also because it has been
proven to reduce the risk of falls and fractures. Osteoporosis Canada
recommends vitamin D supplementation
of 800-2000 IU/day for adults
≥ 50 years of age.
