hello, i'm 20 year old guy. Few years ago due to accident I lost my elbow bone, now it's ankylose at 90? done by doctor to keep it like that, as I was only 16 year old they don't wanted to elbow transplant. So they kept it it like that l. But due to accident I lost my whole right hand skin too which got repeat by plastic surgeon by skin grafting. But after grafting at few places grafted skin had sticked to the bone, near elbow where it is ankylose. Now the skin is in slightly black in color due to grafting, i'm having white complex. My question is can I get my normal skin color back where due to grafting it has turned black and where it had sticked to the bone can it be treated? And how can elbow bone ankylose problem be cured?
