[Experimental-morphologic study of depressed fracture of the skull. Experimental model].

Experimental skull bone models were made and depressed fractures were created. The morphological reactions of the skull bone models were observed to be the same as in human skulls, that is, that the fractures of the inner side were always larger than those of the outer side as a result of the direction of the impacting forces (a so-called classical type of reversed "V" form). The reason for the reversed "V" form of the depressed human skull fractures was discovered by means of these model studies. The reversed "V" form is due to the "HSH" morphological structure. It will be now be necessary to correct the error in textbooks regarding the depressed fractures, especially morphological illustrations.
