title: Hepatic osteodystrophy complicated with bone fracture in early infants with biliary atresia.
abstract: Biliary atresia (BA) is one of the major hepatobiliary abnormalities in infants and one of the causes of hepatic osteodystrophy. Bone disease may be caused by the malabsorption of calcium and magnesium by vitamin D in hepatobiliary diseases in which bile flow into the intestines is deficient or absent. Bone fracture before Kasai hepatic portoenterostomy or within one month after the procedure in an infant with BA is very rare. We herein report two infants: one infant with BA who initially presented with a bone fracture before Kasai hepatic portoenterostomy, and the other at 4 wk after Kasai hepatic portoenterostomy, and also provide a review of the literature. Moreover, we conclude that clinicians should consider BA in infants with bone fracture during early infancy.
