Compared with domestic bones, imported femoral bones are slightly better in material, quality, technology and service life than domestic bones, but the price is also more expensive than domestic bones, generally the price of domestic femoral bones is about 20,000 yuan, and the price of imported femoral bones is about 30,000-40,000 yuan. The normal service life of the domestic femoral head is about 10-15 years, and the service life of the imported femoral head is about 15-20 years, mainly because the imported femoral head uses a more advanced coating than the domestic one, which is more compatible with the bone tissue and can increase the chance of bone growth, and the chance of the prosthesis loosening after surgery is significantly lower than that of the domestic one, and the wear and tear of the imported femoral head on the hip joint is relatively smaller than that of the domestic one. The wear and tear of the imported femoral head on the hip joint is relatively smaller than that of the domestic one. However, due to the progress of technology, domestic artificial joint technology is also developing rapidly, and the gap between imported products will become smaller and smaller in the future.
