This news story conveys 2 messages; One, the almost anything, however unlikely, can happen and two, that it makes no sense whatsoever.
In all my professional career in Plastic Surgery I have never seen, heard or read of such a complication involving breast implants. It just does not happen and you are more likely to be hit by lightning than have this happen to you.
As a Pilates drop out (just could not hack it), all of us know the amount of straining involved laying on your back, "sucking it in" making our backs unnaturally conform to the straight surface while simultaneously performing those core excercises. The result, a continuous Valsalva (or straining of the core muscles as one sees when lifting a heavy weight, which if ANYTHING, would push things out and cause hernias NOT suck things in. The pectoralis major muscle of the chest CANNOT push anything into the chest because it does not cover the entire implant. Since it covers only the top 20-30% of a breast implant, pressure from the muscle will just push the implant away from under the implant. (Try putting your hand on a third of a wet or oily orange or apple and push down hard and you will see this in action). Furthermore, the distances between our ribs is very small and is bridged by layers of tough intercostal muscles (as anyone who ever ate ribs knows). Nothing wider than 0.5 inch can even fit between the ribs and we are asked to believe that a breast implant squeezed in between the ribs, traversing the muscles and ending up in the chest?
Lastly if this woman had such a soft, jelly-like diseased chest wall, how could she engage in Pilates? Arte you kidding me?
If this "news item" was published elsewhere I would call it a hoax.
