Abstract:
As a common disease in orthopedics,osteonecrosis of the femoral head (ONFH) frequently occurs among young and middle-aged people.Hip joint preserving surgery has attracted more and more attention due to the fact that artificial joint prosthesis has a certain useful life and the rate of hip joint revision is high and the higher risk of many complications.There are a large number of operative methods for preserving hip joint in clinical practice without definitive curative effects.Core decompression and impaction bone grafting with simple operative methods can relieve internal pressure of femoral head and pain symptoms,but they cannot remove necrotic bone completely.Hence,they are only used for ONFH in the early stage.Vascularized bone transplantation can fill defects of the former,as it can not only completely remove necrotic bone,but also provide bone graft with nourishing vessels for femoral head,being beneficial to reconstruct the bone structure of femoral head.Subsequently,the application of tantalum rod can provide mechanical support for femoral head to prevent the collapse of femoral head.The emergence of stem cell transplantation has created a new approach to preserve hip joint for ONFH,which promotes the regeneration of bone cells and assists femoral head in repair,often combined with other operative methods and using characteristics of superior proliferation and differentiation of stem cells.Hip joint preserving surgery,in recent years,has been performed increasingly,and has obtained improvement in clinical effects.The multiple combination of a variety of its operative methods provides more effective treatments for ONFH.It is an essential notion that hip joint preserving surgery,however with any operative method,should as far as possible select a surgical plan with little trauma,simple methods and little injury to bone structure of hip joint based on ensuring the efficacy.
