Rickets is a softening of bones in children potentially leading to fractures and deformity. Rickets is among the most frequent childhood diseases in many developing countries. The predominant cause is a vitamin D deficiency, but lack of adequate calcium in the diet may also lead to rickets (cases of severe diarrhea and vomiting may be the cause of the deficiency). Although it can occur in adults, the majority of cases occur in children suffering from severe malnutrition, usually resulting from famine or starvation during the early stages of childhood. Osteomalacia is the term used to describe a similar condition occurring in adults, generally due to a deficiency of vitamin D.[1] The origin of the word “rickets” is probably from the Old English dialect word ‘wrickken’, to twist. The Greek derived word “rachitis” (meaning “inflammation of the spine”) was later adopted as the scientific term for rickets, due chiefly to the words’ similarity in sound. In many languages it is known as “English disease”.
Those at higher risk for developing rickets include:
Individuals with red hair have been speculated to have a decreased risk for rickets due to their greater production of vitamin D in sunlight.
Vitamin D is required for proper calcium absorption from the gut. In the absence of vitamin D, dietary calcium is not properly absorbed, resulting in hypocalcemia, leading to skeletal and dental deformities and neuromuscular symptoms, e.g. hyperexcitability.
A rare X-linked dominant form exists called Vitamin D resistant rickets.
Signs and symptoms of rickets include:
An X-ray or radiograph of an advanced sufferer from rickets tends to present in a classic way: bow legs (outward curve of long bone of the legs) and a deformed chest. Changes in the skull also occur causing a distinctive “square headed” appearance. These deformities persist into adult life if not treated.
