Definition of osteomalacia in English:



  • Softening of the bones, typically through a deficiency of vitamin D or calcium.

    • ‘If blood levels of calcium fall then calcium is withdrawn from bone, resulting in osteomalacia and osteoporosis.’
    • ‘The diagnosis of osteomalacia, made in the past by bone biopsy and more recently by measurements of bone mineral density, may be overlooked in some patients.’
    • ‘Vitamin D deficiency can lead to bone disease: osteomalacia in adults, rickets in infants and children.’
    • ‘Osteoarthritis, osteomalacia, rheumatoid arthritis, gout, and other arthritic conditions may increase the risk of problems originating from surgical positioning.’
    • ‘Calcium and vitamin D malabsorption dramatically increases the risk of osteoporosis and osteomalacia in patients with gluten-sensitive enteropathy.’


Early 19th century: modern Latin, from osteo- bone + Greek malakos soft.
