Sky News viewers who have followed the story of Najib Ali have donated tens of thousands of pounds towards his treatment.
The UK charity Goodwill Caravan has been sponsoring Najib and organised crowdfunding to support him.
Its founder Hanan Ashegh said: “It’s a miracle.
“He’s got a straight back.”
I’ve been following the plight of Najib Ali for nearly two years.
When I first met and reported on him, Najib and his family were stuck in Greece unable to get the medical help they needed.
Najib has undergone surgery at Great Ormond Street Hospital in London.
The operation was carried out by orthopaedic surgeon Ramesh Naderajah.
He told me: “We use about 25 to 32 screws.
“It’s a very complex operation.
“The key thing is that there are other bits of shrapnel in his back which can make the operation to straighten it more difficult.”
Sky News filmed as the specialist team cut deeper and deeper into Najib’s back to reveal his spine.
They then used state of the art rods and screws to straighten his back carefully positioning and securing each one.
Several hours in and the surgeons reached a huge fragment of shrapnel from the airstrike which was still lodged in Najib’s back but was too deeply embedded to remove.
The operations lasted for more than six hours.
Najib has undergone rehabilitation at Royal National Orthopaedic Hospital in Middlesex.
He is able to manoeuvre himself for the first time in nearly six years since the airstrike in Syria.
Najib said: “Before the operation my back was in pain.
“I’d cry all day because of the pain.
“And the pain would affect my knees, my body and my shoulders.
“Thank you everyone who donated and to the charity for helping me.”
The procedure isn’t a miracle cure enabling Najib to walk again but it has improved his and his mother’s quality of life dramatically.
His mother Faten Sh’houd said: “Najib was always on my lap.
“I’ve always carried him like a five-month-old baby and had to look after him.
“Before the operation everything was difficult for him.
“I was responsible for everything he did. I would always be with him.
“Now I’m much happier that Najib is better. Najib’s situation has improved and I ask God to help him with his treatment so he can improve even more.”
Goodwill Caravan’s fundraising for Najib has finished but the charity says there are many more children in Greece who need their help.
Founder Hanan Ashegh said: “When we see Najib now he’s almost unrecognisable.
“He’s with a straight back.
“He can take a full breath.
