Example of a femoral shaft fracture where the degree of fracture fragment displacement is grade IV. A A 28-year-old man sustained a right femoral shaft fracture with a fracture fragment; B the lateral view after closed reduction showing that the fracture fragment is turned over and greatly displaced (grade IV displacement); C the lateral view at 3 months postoperatively showing that the fracture site defect and that the medial callus has grown well; D the lateral view at 3 months postoperatively showing that the fracture fragment is free in front of the shaft and that the callus has grown well behind the fracture; E the anteroposterior view at 1 year postoperatively showing good medial callus growth and the lateral bone defect at the fracture site; F the lateral view at 1 year postoperatively showing partial absorption of the free fracture fragment
