Toddlers whose fingers are crushed by closing doors can end up with lifelong problems, plastic surgeons are warning.
Parents are being urged to fit safety catches to all doors to prevent the accidents from happening.
The British Association of Plastic and Reconstructive Surgeons (Bapras) said the injuries in some cases could lead to amputation and long-term pain.
About 30,000 children trap their fingers in doors each year and more than 1,500 of them need surgery, according to the Royal Society for the Prevention of Accidents.
It says more than two million children under 15 have accidents in and around the home every year and require emergency medical care.
According to Bapras, self-shutting fire safety doors, car doors and hinges are the top three causes of finger and hand injuries in children.
It recommends putting small C-shaped devices made of foam or rubber over doors to prevent them slamming – but these are not suitable for fire doors because they prevent the door from closing.
Hinge protectors can also be fitted on most doors.
Bapras spokeswoman Anna De Leo, a plastic surgeon at the Royal Free Hospital, London, said: “The injuries are so serious that the patient would need to undergo a clinic appointment, an X-ray, day surgery, a follow-up nurse appointment and possibly physiotherapy.”
And she said the effects could be long-term.
“It’s easy to underestimate how important your hands are to doing everyday tasks.
“Injuries to fingers and hands mean tying your shoelaces, typing, holding a mobile phone or eating become a lot more challenging.
“And this is nothing compared to the impact of a finger amputation.”
Ms De Leo said people in that situation could also experience elbow pain, migraines and even depression.
“Fingertip injury alone can result in 20 per cent loss of hand strength and can prevent people from pursuing their chosen career,” she added.
