Bilateral fracture of the surgical neck of the humerus in a patient with osteomalacia.

Bilateral fractures of the humeral surgical neck occurred in a 62-year-old woman, subsequently found to have osteomalacia secondary to primary biliary cirrhosis. Treatment was conservative with good result. After an extensive search of the literature, this is believed to be the first reported case of bilateral fractures of the surgical neck of the humeri without associated posterior dislocation. There has also been no previous report of fracture as the presenting symptom of primary biliary cirrhosis.
