A Report of One Hundred and Thirteen Cases of Diaphyseal Fractures Treated with the K-U Compression Plate

Abstract

113 cases of diaphyseal fractures which had been treated with the K-U compression plates were collected and discussed. Cases of delayed union or none union were seven that formed 6.2 per-cent of all cases, almost all of cases resulted in unsuccessful bone union, dued to inadequate technique of surgery and unsuitable treatment after surgery. Only two cases showed spongeal appearance of cortical bone. And other two cases gave rise to refracture after compression osteosynthesis. It was assumed that some of the causes of refracture were loss of stress to bone by existence of a compression plate.
