Femoral head replacement is more commonly known as hip replacement surgery. The time to abandon the abduction varies according to the patient’s physical condition, and generally it can be abandoned 1~2 months after the surgery. The time to abandon abduction after hip replacement is mainly related to the healing of the fracture and the recovery of the muscle strength of the lower limbs. For patients who need hip replacement due to trauma and fracture with a relatively short period of time, they can abandon the abduction because the muscles have not atrophied or are only mildly atrophied, and they do not need to carry out muscle recovery training for a long time, and they can recover after about 1 month. For some older patients, patients with serious underlying diseases such as severe osteoporosis or patients with muscle atrophy of the lower limbs due to prolonged bed rest, it is necessary to carry out functional exercises of the lower limbs after the operation to gradually restore the muscle strength of the lower limbs, and it usually takes about 2 months to give up the crutches. In addition, it is not recommended to carry out heavy weight-bearing exercise after hip replacement surgery, so as not to cause the prosthesis to loosen. Post-operative recovery treatment after hip replacement is recommended to consult the doctor in time and under the guidance of the doctor.
