Clinical and experimental morphological study of depressed skull fracture.

Ninety-eight cases of depressed skull fractures, caused by various accidents, were treated. The morphological structures of the fractures were studied. Thirty-four depressed fractures were established experimentally, and a comparable study was performed. Clinically and experimentally I confirmed the same morphological reactions, that is, that the fractures of the inner region were always larger than those of the outer side, as a result of the direction of the impacting forces. The human skull suffers depressed fractures only because it has "HSH" (hard-soft-hard) histological structures. It is naturally disadvantaged.
