[Biomechanism of intracranial and spinal trauma of child born in occipitoanterior presentation as used in forensic examination].
The new conception of mechanism and sequence of damages typical for labor trauma is presented: injury of ligaments of atlas and axis and anterior atlanto-occipital membrane, ruptures of synchondrosises of cranial bones because of vertebral column pressing on occipital bone; tears of dura mater of brain upon basilar impression in the area of focal spot; subarachnoid hemorrhage and intracerebral bleeding in case of cerebral compression by bone borders where they overly override; ruptures of ligaments of cervico-occipital and intervertebral joints in case of excess flexion and overextension of head. Authors show that damage of sutures, bones of calvarium and partition parts of dura materialize later than injury of synchondrosises of base and they are absent if sinchondrosises are not damaged. Also iatrogenic damages of fetal in labor and the mechanism of their formation are described.
