The key point of adult hip preservation to femoral head necrosis:recognize and reconstruct anterolateral column of the femoral head
Along with efforts and development for half century,we come to a new era in the prevention and treatment of femoral head necrosis(FHN).At present,early femoral head necrosis is more easily detected with the economic development,improvement of living standards,updating and popularizing of medical equipment,and contributions of former orthopedic experts.The authors brought up that the key point of hip preservation to femoral head necrosis was to recognize and reconstruct the anterolateral column of the femoral head.There are several effective methods to reconstruct anterolateral column of the femoral head,including basicervical femoral neck rotational osteotomy(BCFNRO or BCRO),intertrochanteric varus osteotomy(ITVO),intertrochanteric rotational osteotomy(TRO),iliac bone support autograft(IBSG)to anterolateral column of the femoral head via surgical hip dislocation(SHD),etc.The tasks in clinical practice on FHN include early detection of the FHN,exact assessment of the collapse risk,effective follow-up and personalized treatment on time based on precise stage and type.Furthermore,pathological mechanism,penetrated molecular biology research,accurate biomechanics analysis,damage and repair of the cartilage of FHN,and artificial intelligence(AI)should be carried out soon.
