Fig. 13A. Radiograph showing the head and neck of the femur (natural 

 size) excised following a bilateral intertrochanteric fracture in a 78-year-old 

 woman with severe osteoporosis. The split in the superior margin of the head 

 was produced by insertion of a hip skid. Note the accentuation of the vertical 

 trabecular markings. The thin cortex and hollow neck are indications for ex- 

 cisional surgery or bone pegs, rather than internal fixation with metallic ap- 

 pliances. 



Fig. 13B. Microradiograph of the superior cortex of the neck of the femur 

 in the case shown in Fig. 13A. Note the hypermineralized avascular bone on 

 the right and the attenuated discontinuous cortex in the center. ( X approx. 75.)
