A shocking video emerged today showing a grotesque bulge in a woman's buttock apparently caused when her botched silicone implant 'flipped inside out'.
Instead giving her a smooth, plump appearance, the implant has popped out and is left protruding in an ugly disc shape at the back of her cheek.
In the 20-second clip, the unidentified woman slowly manipulates it back into place while explaining: 'This is my implant flipping backwards'.
She adds: 'I don't think an implant's supposed to do that. It shouldn't be able to flip.'
The video has been 'liked' by 278 people on Facebook and shared nearly 20,000 times.
One user, Donna Wright-Levy, commented: 'I prefer to go harder on the squats, lunges, hamstring curls and the gluteous kickbacks...'
Kader SmileyFace said: 'Uh!! Why would she want a bigger ass!'
It is difficult to establish whether the video is genuine and no details are known about which clinic the woman went to or exactly what type of procedure she had. But BAAPS Member Adrian Richards, a consultant plastic surgeon at Aurora Clinics in the UK, believes the clip is authentic.
He said the problem occurs when the implant is not secured firmly enough in a 'pocket' the surgeon creates either between the buttock and the pelvic bone or on top of the gluteus maximus.
'It is a complication which is relatively common following buttock implants. It shouldn't really happen because the pocket should be snug so the implant stays where it is. 'This lady's implant is flat on the bottom and coned on the top, but this one has flipped over.'
He said it wouldn't be painful, but would likely need to be removed or the pocket closed up to stop it shifting around.
Buttock implants are popular in South America, where plump bottoms are regarded as sexually desirable.
In recent years, plastic surgery experts have been warning women not to have operations in unapproved clinics after a string of deaths and dodgy practices.
In April last year, a 42-year-old mother-of-three died after buttock implant surgery at a backstreet Las Vegas clinic.
Elena Caro's family begged her not to have the operation, saying she was beautiful as she was, but she went ahead with the surgery.
She was found crying in agony and begging for help after an unlicensed Colombian doctor allegedly dumped her by the side of the road when the procedure went wrong and she died in hospital a short time later.
