Thank you for your question regarding whether a intramuscular buttock implants rip through the muscle. The answer is "yes, very rarely." It is very rare that an intramuscular buttock implant rips through the muscle. When the buttock implant is inserted, the fascia on top of the buttock implant is closed usually with permanent or semi-permanent sutures. I have not had any cases where the buttock implant migrates or rips through the buttock muscle. Conceptually, buttock implants tearing through the gluteus maximus can happen, but it would have to have a tremendous amount of force to do so. The force that this would require would be something like a fall from 30- 40 feet. Therefore, I believe it is extremely rare for a intramuscular buttock implant to rip through the muscle. Thank you for your question about permanent buttock augmentation with FDA approved, semi-solid silicone buttock implants.
