In recent years worldwide there has been a considerable increase in the number of middle and older aged patients who undergo total hip replacement, and following surgery they would again
like to live an active life, therefore they take part in everyday traffi c as either drivers or passengers of motor vehicles. In head-on collisions there is a relatively high rate of thigh bone, hip joint and pelvic fractures or traumatic dislocation of the hip joint the so called dashboard injury, in cases like this a replaced hip is exposed to greater dangers. We searched the literature for biomechanical examinations of these special joint circumstances, since the replaced hip can not be compared
to a healthy hip either biologically or mechanically. The reason this is important, because in these patients it might be advisable to fi nd a solution that takes this into consideration during surgery. We could not fi nd literature examining this question on the internet to this day.
