An 11-year-old boy cut half of his tendon in his handwhen he fell on a discarded piece of glass while playing in a park.
Mum Kristy Marie said her son risked losing movement in his fingers had the incision been just a little bit deeper.
She was with her family in a park in Aberdulais, Wales, on Saturday, when her son suffered the huge cut.
The wound went across his hand from the base of his thumb right across to the other side of his wrist.
The injured boy initially “panicked” and ran away but when he finally made his way back home, his mum realised his wound wasn’t something first aid could fix.
He was whisked to hospital for treatment and doctors decided the incision was too deep for stitches.
Mum-of-three Kristy Marie said her children play in the park on a regular basis but she is now uncertain she’ll take them again as she claims it is not the first time she sees hazardous material lying around.
Recollecting the horrifying experience, Kristy Marie said: “He ran away when he first cut it because he was panicking and he didn’t want to come home.
“I looked at it and it was too big to do first aid so I took him to Neath Port Talbot Hospital.
“The doctor said he couldn’t stitch it because it was too deep and had severed 50 per cent of a tendon.
“If it had gone any lower we were worried he was going to lose movement of his fingers. He has been putting on a brave face, trying to be brave for me, but it is painful and he’s trying to hide it”.
The mum-of-three said the area where her son was hurt was often littered with broken bottles and other rubbish from young teens and warned other parents to be on their guard.
She added: “There are a lot of older teens in the park and down by the river, who go there drinking, and it looks like they are leaving bottles there and smashing them.
“My five-year-old daughter likes to go to the park to play as well, but I’m not sure when I will take them again because I don’t want to bring it all back to them.”
Aberdulais ward councillor Doreen Jones added: “I have been in touch with family and as soon as I knew about the issue I asked the parks department to go and clean the area.
“Unfortunately if people leave litter there is the chance of it causing accidents”.
