In postcollapse hip avascular necrosis (AVN), the femoral head cannot be salvaged, necessitating total hip replacement. We report a case of a 39-year-old woman who developed idiopathic femoral head AVN with marked symptoms and radiological evidence of articular surface collapse. We treated her with core decompression combined with the 'diamond concept' (implantation of bone marrow concentrate, a growth factor and bone graft substitute) and distracted the hip joint with external fixator. Four years postoperatively the articular surface has been restored and the patient reports excellent quality of life. Hip arthrodiastasis with core decompression and 'diamond concept' regeneration could be considered a treatment option in advanced AVN of the femoral head.
