[Hyperphosphatasia and hypophosphatasia in childhood].

The treatment of phosphate diabetes and hyperphosphatasia requires an interdisciplinary therapy concept between paediatricians and orthopaedic surgeons. The surgical challenge is the correction of the multiplanar bending deformities and the pathological fractures. Different techniques are discussed in the literature without an outstanding recommendation for a special approach. This contribution gives an overview of the published methods and discusses various surgical concepts in view of our own clinical experience.
