Changing the pelvis is different from changing other bones and joints. The tissue of pelvis is very complicated. The main blood vessels from the heart to the lower limbs and the nerves innervating the lower limbs all pass through the pelvis. At the same time, the connection between pelvis and surrounding muscle tissue is also very complicated. A slight negligence in the operation may cause massive bleeding, or damage the nerves that dominate the lower limbs, or the surrounding muscle tissue cannot naturally blend with the metal pelvis, affecting the function of the hip joint and leg, and the operation risk is high. The first pelvic replacement operation in China was performed by Shanghai Ninth People's Hospital in 2000, and it has been performed in Beijing ever since. The number of cases in China is limited, and developed countries in Europe and America do not do much.

Pelvic replacement surgery is mainly used for the above-mentioned bone cancer patients. As for pelvic injuries caused by other reasons, such as car accidents, use other methods to make bones heal slowly. After all, it's better to grow yourself than to replace the metal pelvis.
