1. No attempt has been made to compare the bone graft with other methods of treatment for ununited fractures of the neck of the femur. The fact that a review of twenty-six years' work in a large surgical clinic revealed only seventy-seven cases in which bone-grafting was employed testifies to the caution with which the method has been used. It has, been employed in treatment of about one in ten of the ununited fractures of the neck of the femur encountered.
2. The patients were mostly less than fifty years of age, and the average age was forty-six years, emphasizing the fact that, to the present time, use of the bone graft has been confined to the younger group of patients.
3. The author has presented his findings in this series of cases because there are too few reports on the subject in the literature, and because he believes that, with the improved technique by which the channel for the bone graft is drilled over a guide wire, thus removing the necessity of opening the joint, the field for bone-grafting will be widened.
