case_images: Her right side was deformed inwardly (Figure 1).
case_images: Computed tomography coronal image demonstrating a circumferential fracture and surrounding osteosclerosis of the femoral neck on the right side (a) and the medial fracture on the left side (b).

case_images: fig2
case_images: Computed tomography revealed fracture lines and surrounding osteosclerosis around the entire femoral neck on the right side and medial fracture lines on the left side (Figures 2(a) and 2(b)).
case_images: Postoperative radiograph demonstrating the treatment with bipolar hemiarthroplasty of the femoral neck on the right side and with osteosynthesis on the left side.

case_images: As the displacement occurred between bone fragments on the right side of the femur, bipolar hemiarthroplasty was performed to hold the loaded limb during the transfer postoperatively (Figure 3).
case_images: Histology of the fracture site. An increase in the empty lacunae is observed in the thickened bony trabeculae under low magnification of the bone sample around the fracture site (100x).

case_images: Additionally, there were a few cells, such as osteoclasts, on the trabecular surface and many empty lacunae in the bony trabeculae (Figures 4 and 5).
case_images: Histology of the fracture site. In the high magnification of the region (200x), thickening of the bony trabeculae with few cells on the surface is observed in the fracture site.

case_images: Additionally, there were a few cells, such as osteoclasts, on the trabecular surface and many empty lacunae in the bony trabeculae (Figures 4 and 5).
case_images: A left hip radiograph obtained at 1 year postoperatively demonstrating a radiolucent line around the implant that was not present immediately postoperatively.

case_images: The modified Harris hip score at 1 year postoperatively was 94/96 (right/left), and osteosclerosis of the fracture became less noticeable but persisted (Figure 6).
