The subject I have chosen for this paper is the question of blood supply in fractures of the neck of the femur. Because of the possibility of inadequate blood supply, it is my belief that the treatment of this fracture is a special problem differing from that of all other fractures. It is the most unfavorable of all fractures as to union, so unfavorable that Dr. Kellogg Speed of Chicago, when invited to deliver an oration on fractures before a recent congress of the American College of Surgeons, chose this particular fracture as his subject, designating it "the unsolved fracture." It may also be noted that Sir Ashley Cooper went on record as having said that he had never seen a fracture of the neck of the femur that had united.
The British Commission on Fractures has reported 22 per cent of union in all types of treatment of fractures
