Help young boy walk again

Hello my name is Selma and I’m organizing the fundraiser to help my nephew Metin. He is 15 years old and he has gone through two different surgeries of his right leg and he needs a third surgery. He hasn’t been able to walk for almost one year and half and he hasn’t been able to attend school neither. He has gone through multiple physicals as well but with the both surgeries his leg is worse and it’s five centimeters shorter. The third surgery needs to get done in Turkey and it will cost $10 000. My brother is the only one working and providing for his family. He is currently facing financial challenges in order to afford the necessary surgery for his son. Your help will be much appreciated.
