Using acupotomology incise and separate the hip joint articular capsule and ligament and the periosteum on the collum ossis femoris and the soft tissue nearby the joint can cause slight hurt and haemorrhage. The hurt factor is release from the local tissue. Human self-rebuilding system is activated, Building bone function of osteoblast is accelerated, new bone is built quickly. New blood vessel and nerve ending is rebirth. Local tissue's blood supply and nerve nourishment is improved. The developing of bone necrosis is prevented. The necrotic part is re-blood vessel. The conditions of the necrotic's absorbing tissue and the new bone's replacing are established.

Two cases were isointense or hypointense signal on T1WI and heterogeneous hyperintense signal on T2WI and T2WI STIR. Conclusion Enhanced CT clearly showed calcification and blood supply of the tumor while MRI showed small hemorrhage, cystis foci, necrosis and central stellate scar of the tumor. MRI can provide more useful information in detecting chromophobe cell renal carcinoma.
