Fracture classification and displacement degree.
Radiograph showing a Delbet type-Ⅲ femoral neck fracture with significant displacement.
Fig 2.
Unsatisfactory reduction: The widest distance of the fracture ends is obvious (more than 10mm); the diaphragm is poorly aligned (more than 10°).
Fig 3.
The last follow-up evaluation at 12 months postoperatively.
Radiograph reveals irregular femoral head shapes, changes in density, and the presence of avascular necrosis of the femoral head.

Fracture classification and displacement degree.
Radiograph showing a Delbet type-Ⅱ femoral neck fracture with insignificant displacement.
Fig 5.
Satisfactory reduction: The fractures ends have good alignment, no displacement and no angle.
Fig 6.
The last follow-up evaluation at 12 months postoperatively.
Radiograph reveals regular femoral head morphology, uniform density, and no avascular necrosis of the femoral head.
