The most typical and common complication is periosteal contracture, which needs to be solved by the second or even multiple surgeries, and the breast of the prosthesis will be as hard as a stone in serious cases; 2. The brands of prosthesis on the market are many and varied, and are updated quickly, and the price difference is so big that it is difficult to distinguish between the real one and the fake one and the quality is difficult to be guaranteed; 3. Prosthesis has a certain shelf-life, and it will produce various problems if the time is too long, so it is necessary to carry out a surgery for taking out the prosthesis when necessary; 4. Prosthesis has been placed in the chest for about ten years. After that, the ribs may be bent by the implants and even rupture of the chest may occur (removed).
