Rickets is a disorder due to impaired metabolism of bone mineralization which caused by low concentrations of extra-cellular calcium or phosphate. In children, hypophosphatemic rickets (HR) happen malabsorption of phosphate and increasing of renal tubular loss.
We present the case of a 4-year-old girl who had medical history of HR with failure to thrive (FTT). Child hospitalized several times due to osteomalacia and leg fractures. In physical examinations, there were obvious signs of rickets such as bow legs and hands, deviations of the wrist and chest pigeon. The results of blood tests showed low level of Phosphorus; but the level of calcium was normal. Radiography showed deformity of wrists and hands.
HR should be considered as one of the childhood disorders which impairs metabolism of bone mineralization and cause osteomalacia and bones fractures. If HR undiagnosed and remedies poor during childhood, in older ages would reveal automatic fractures and mineralization defects.
