So are hip implants safe? I'v been searching for the answer to my narrow hips for years and I'm not convinced I have enough fat for transfer. I found a doctor...FINALLY...who's performing this new surgery of solid silicone hip implants to the hips but the only problem is there's NO information out there on it. I'm really hoping this is the answer for me but I dont want to be a lab rat. What are the complications? Is there a reason why hip augmentation hasnt been popular before?
