Fig. 3From: The small screw-apex distance is potentially associated with femoral head osteonecrosis in adults with femoral neck fractures treated by closed reduction and percutaneous 3 parallel cannulated screwsAn 81-year-old female patient suffering from a right femoral neck fracture was treated with artificial hip replacement. The femoral head was cut with a saw near the centre on the coronal plane after the femoral head was removed, with the weight-bearing region just above the femoral head. Here, we aim to show the principal compressive trabecular structure. * ExtractorBack to article page
