Abstract

This study proposes that the mechanism of traumatic posterior dislocation of the hip (TPDH) is a brake pedal injury rather than a dashboard injury. A total of 168 cases of TPDH were treated during the past 10 years. Clinical records of 48 patients, who were drivers and suffered from a head-on collision accident, were examined. The right hip was involved in 45 cases. A total of 31 cases were not accompanied by knee injuries. In 11 cases with foot or ankle injuries and right hip dislocation, 10 had right foot or ankle injuries. If the mechanism of TPDH was a dashboard injury, the left hip would be involved more frequently and there would be more knee injuries. Our hypothesis about the mechanism is that, in a head-on collision, the driver presses desperately on the brake pedal with his right hip slightly flexed, adducted and internally rotated.
