Results of the operative treatment of phosphate-diabetes are presented on the basis of our own patients. Deformations of the lower extremities need in case of a disturbed function and disfigurement of the gait picture a surgical correction, by which we should strive as much as possible for physiological axial proportions in both planes.

An adequate straightening, combined with a regular control of the mineral metabolism and an appropriate drug therapy, guarantee good long-term results and absence of recidivity.
