FEMUR 13 BONE AND WHICH PART FRACTURE ORIENTATION AND PARTS DISPLACEMENT AND ANGULATION JOINT INVOLVEMENT DESCRIBE THE FRACTURE AP LAT 14 There is an oblique fracture through the diaphysis of the femur with approximately 1cm of lateral and anterior displacement of the distil fragments relative to the proximal fragments. There is no angulation at the fracture margin. There is some shortening due to unopposed muscle pull. The fracture does not extend into the joint.
