[Pathomechanisms of spinal cord injuries caused by injuries of the cervical spine].

The pathomechanism of injuries of the spinal cord due to injuries of the cervical spine in 158 patients treated during the last ten years has been presented. It has been determined that total and irreversible injuries of the spine occurred most often after fractures of the spine with displacement from hyperflexion (29.7 per cent) crushed fractures (24.7 per cent), and dislocation of the spine (24.7 per cent). In the majority of the patients, the spinal cord was irreversibly damaged already at injury, and in 29.2 per cent, the symptoms of deformity of the lumen of the vertebral canal and compression of the spinal cord remained. In about 24 per cent of the patients, the symptoms of congenital or habitual relative stenosis of the vertebral canal occurred. The performed examination has shown that knowledge of the pathomechanism of injury of the spine may facilitate determination of the degree of injury of the spinal cord as early as immediately after trauma.
