After neck of femur fracture surgery, generally 3 months to start walking with crutches and weight bearing, slowly partially weight bearing, to about half a year, generally can achieve full weight bearing and abandon crutches walking, but must be in the hospital to take X-rays, showing that the fracture is completely healed before abandoning the crutches to walk. Femoral neck fracture itself is one of the most difficult fractures to heal, and subcapital fracture is the most serious type of femoral neck fracture, which damages the joint capsule and blood flow of the femoral head, and easily leads to delayed healing, non-healing of the fracture, and even necrosis of the femoral head. If you bear weight too early, increase the pressure on the femoral head, it will reduce the blood transportation of the femoral head and increase the rate of ischemic necrosis of the femoral head. Therefore, under the guidance of a doctor, you can only walk with weight bearing and abandon the crutches when the X-ray shows that the fracture line has disappeared and the fracture has completely healed.
