[Humerus varus congenitus (author's transl)]

Two cases of humerus varus congenitus have been treated by lengthening of the humerus using an external distraction device. The first was lengthened by about 6 centimetres and the second by about four centimetres. In one case, primary bone union was obtained and in the second, secondary grafting had to be done. The clinical results were satisfactory.
