Osteomalacia (C0029442)

Definition (MSH) Disorder caused by an interruption of the mineralization of organic bone matrix leading to bone softening, bone pain, and weakness. It is the adult form of rickets resulting from disruption of VITAMIN D; PHOSPHORUS; or CALCIUM homeostasis.
Definition (NCI_NCI-GLOSS) A condition in adults in which bones become soft and deformed because they don't have enough calcium and phosphorus. It is usually caused by not having enough vitamin D in the diet, not getting enough sunlight, or a problem with the way the body uses vitamin D. Symptoms include bone pain and muscle weakness. When the condition occurs in children, it is called rickets.
Definition (NCI) A metabolic bone disease that results from either a deficiency in vitamin D, or an abnormality in the metabolism of vitamin D, or a deficiency of calcium in the diet. The most common symptoms are bone pain and muscle weakness. When it occurs in children it is commonly referred to as rickets. (Diagnostic Surgical Pathology, 3rd ed.) --2003
Definition (CSP) inadequate or delayed mineralization of osteoid in mature cortical and spongy bone.
