Vitamin D deficient ricket is now a rare disease in the developed countries because of the generally improved nutrition and medical awareness but occasional cases are found in the special susceptible populations. The ricket is characterized pathophysiologically by a failure of the normal mineralization of bones and epiphyseal cartilages and is susceptible to the fractures because of the weakness and increased plasticity of bones. The fractures occurred in rickets are known to be delayed in union but it should be normal if the ricket is effectively treated. Authors reviewed 7 cases of fractures occurred in the vitamin D deficient rickets which were managed at Daegu Fatima Hospital during the years from 1980 to 1986 and the following results were obtained. 1. The cases were 4 boys and 3 girls having ages from 6 to 11 years who were all in the same group of restricted population of poor nutrition. 2. 10 fractures noted in 7 cases including two cases of multiple fractures and a case of refracture and most of the fractures occurred in femurs except for a humerus and a forearm bones. 3. The causes of fractures were uncertain because the definite histories were unable to obtain but any violent trauma was not suggested. 4. The fractures were treated by the usual methods of skin tractions or cast immobilizations and daily doses of 2,000 U. or 5,000 U. of vitamin Dwere given as soon as the rickets are recognized. 5. The normal healing of the fractures and rickets occurred in the cases who were given vitamin D initially when the diagnosis of rickets were made. 6. The healing of fractures were very delayed in 2 cases who were missed to recognize the rickets initially and vitamin D was not given.
