Patients with necrosis of the femoral head are not recommended to do physical work regardless of the treatment methods. 1. For patients with conservative treatment: if the patient chooses conservative treatment, regular physical work will increase the weight of the hip joint, which will aggravate the clinical symptoms and lead to the possibility of aggravation of the disease. 2. For patients with surgical treatment: For patients who choose surgical treatment, regular physical work will reduce the service life of the prosthesis and may cause clinical symptoms such as hip pain and discomfort. For patients who have not undergone artificial joint replacement but hollow nail internal fixation, engaging in physical work is also quite dangerous, which will easily lead to breakage of the internal fixation nail and aggravate the risk of femoral head necrosis. Please consult the attending doctor in detail about the living and working intensity of femoral head necrosis surgery and do not labor blindly.
