Traumatic dislocation of the stem of hip joint uncemented endoprosthesis

Traumatic dislocation of the stem of hip joint endoprosthesis is a complication which has not been reported so far in literature. It requires surgical treatment whose delay may result in soft tissue incrustation by metal filaments due to friction of the internal hip joint acetabulum and head of the endoprosthesis. In our center, a woman after low-energy(impact) injury was operated on due to painless shortening of limb length accompanied by subjective sensation of crepitus during joint movements.
