The greatest risk of femoral neck fracture is non-union and femoral head necrosis, with the greatest risk of fracture at the craniocervical junction. The risk of nonunion and femoral necrosis increases with age. The risk of non-union and femoral head necrosis is as high as 90% for craniocervical junction fractures over 60 years of age. Therefore, total hip replacement in one stage is the best treatment option for such patients. The drainage tube was removed 2 days after surgery, and the patient was able to walk on the ground 3 days after surgery, walk without crutches 45 days after surgery, and start to practice squatting 3 months after surgery.
