Twenty seven fractures of the femoral neck in 26 elderly patients treated by primary replacement with the endoprosthesis were reviewed. The end results of 18 hips of 17 patients who were followed up at least over 6 months were as follows. The average age was sixty-seven years. Seventeen fractures occurred in women and ten in men. Of these 18 hips, eleven hips were excellent or good. Poor results were in two hips; one developed deep seated infection and the other patient who could walk with crutch after bilateral endoprosthetic replacement because of Lt hip pain. It is considered that this method is the best treatment in the rehabilitation of elderly patients after high femoral neck fracture, because of its low morbidity and high success rate in returning the geriatric orthopaedic patients to independence.
