All the patients presented symptoms of nerve system at different degrees. They were treated with AO pure titanium cortex screw through isthmus after skull traction replacement. Results All the patients were followed up for 12 to 60 months. According to Frankle classification, 6 cases of Grade D and 5 cases of Grade C recovered up to Grade E, 2 cases of Grade C recovered to Grade D, 1 case of Grade B recovered to Grade C and 1 case of Grade B recovered to Grade D.
