Imaging studies. a: Plain radiographs of both femurs reveal femoral neck fractures. (right, Garden III fracture; left, Garden IV fracture) b: Coronal T1-weighted image demonstrates low-intensity femoral neck fractures and the T2-weighted image shows high-intensity bone edema. c: ^99mTc-hydroxymethylene diphosphonate (HMDP) scintigraphy demonstrates significant abnormal uptake in calvaria, maxilla, both scapulae, ribs, both femoral necks, right condyle of the femur, right tibia, and both tarsi. d: Plain radiographs of hip joints in which total hip arthroplasty was performed by inserting an implant in the left hip joint.
