Femoral head necrosis is a common orthopaedic disease. As we age, the incidence of femoral head is increasing. For some patients with milder symptoms of early femoral head necrosis can be treated conservatively to help maintain their health and keep the condition under effective control. For patients with more severe disease, conservative treatment can only help relieve the symptoms and should be actively treated with surgery. The two main clinical methods of conservative treatment are medication and physical therapy to relieve and control the patient’s condition. Medication, by taking non-steroidal anti-inflammatory drugs to relieve pain and promote repair; by improving local microcirculation through anticoagulants and microvascular dilating drugs; by taking drugs to regulate bone metabolism to prevent femoral head collapse; and by taking oral Chinese medicine at an early stage to invigorate blood circulation and reduce symptoms. Physiotherapy can help relieve the pain caused by femoral head necrosis and promote the repair of necrotic bones. The use of a cane and the training of hip mobility can help improve as well as exercise the function of the hip joint. For some patients with early-stage osteonecrosis, conservative treatment can help relieve the symptoms and may even cure the disease. Paying attention to improving the living habits and strengthening the care of the femoral head during normal times is beneficial to the recovery of the body. However, once the disease develops and the symptoms are obvious, you should actively receive surgical treatment.
