[Craniotabes, craniomalacia (Wieland) and active ricketts in infants].

The symptom "craniotabes" means rickets only in few cases. Determinations of calcium, alkaline phosphatase, phosphorus and if possible 25-OH-vitamin D are necessary for confirmation of the rickets-diagnosis. As denotation for the not rickets-caused forms of craniotabes the definition positioning caused craniotabes is suggested.
