Abstract
The skeletal pain and fatigue are the most common symptoms for adolescents' rickets. Most often, symptoms consist of diffuse pains, with radiologic signs of skeletal demineralization and/or signs of bone resorption. For this reason; adolescent patients with nonspecific skeletal pains, with a life style and clothing habits hindering sunlight exposure should be carefully investigated for nutritional rickets as pediatric and adolescent bone mass influences the final course of skeletal health in adults. We describe two teenage siblings, had bone pain and back pain, and sometimes contraction of their hands, accompanied by a severe hypocalcaemia that they had been diagnosed as adolescents' rickets.
