Fig. 1From: Characteristics of subsequent contralateral proximal femoral fracture: more convenient access is needed to treat osteoporosisChanges in Singh index in patients with PFF. A The Singh index of both proximal femurs was grade I at the time of the initial fracture and remained grade I when the contralateral fracture occurred. B Tension trabeculae (short arrows) and pressure trabeculae (long arrows) at the proximal femur were visible at the time of the first fracture, and the tension trabeculae disappeared and pressure trabeculae decreased in severity at the time of the contralateral fractureBack to article page
