The healing time of subcapital femoral neck fracture insertion is at least 3 months, and some of them may have delayed healing or even no healing. Subcapital femoral neck fracture disrupts the blood supply to the femoral head and is more likely to lead to ischemic necrosis of the femoral head, which is slower than normal fracture, and in severe cases, necrosis of the femoral head may occur. After incarceration, due to malalignment of the fracture ends, it is more likely to lead to necrosis of the femoral head, and the healing time is even longer. Therefore, it is recommended that in the case of head-inferior femoral neck fracture with insertion, the surgeon should perform surgery as much as possible after evaluation of the condition, to restore the anatomical structure between the femoral head and the femoral neck through closed reduction, and then implant the internal fixation to stabilize the fracture end and enable the fracture to heal better. In most cases, the fracture is basically healed when the X-ray is reviewed 3 months after the operation, and the fracture can be gradually put down to the ground for weight bearing; for a few fractures that are slow to heal, the time to go down to the ground can be delayed under the guidance of the doctor.
