Preoperative & postoperative anterior and posterior x-ray images of the injured hip with INTERTAN™ nails resulting in iatrogenic fractures in an obese patient then fixed with short and long INTERTAN™ nail. (A) Preoperative anteroposterior X-ray image of the injured hip. (B) Postoperative anteroposterior X-ray image of the injured hip, showing the iatrogenic fractures of the proximal femur (C). Preoperative anteroposterior X-ray image of the injured hip of another obese patient (D). Based on our experience we kept the vertical trajectory with the nail insertion and fully reamed the medullar canal of the proximal femur, of the case in Figure 2A/B, with the anatomical specificity of an extremely narrow proximal canal (arrow). (E) With this improvement, a relatively smooth insertion was achieved (arrow).
