A teenage Welsh international has had her promising career halted by a dead shin bone. Hannah Bluck, 18, from Porthcawl, south Wales, had her dreams shattered after a rare condition ruled her out of the game for two years. The teen football prodigy was warned by doctors that her leg could collapse into her ankle after being diagnosed with avascular necrosis in her distal tibia. Wales' Hannah Bluck, 18,  has had her promising career halted after suffering a rare condition . The 18-year-old has played for the Wales youth national teams at U19, U17 and U16 level . Avascular necrosis is bone death due to poor blood supply. The flow of blood to a section of bone can be interrupted if the bone is fractured or the joint becomes dislocated. The condition can lead to the eventual collapse of the bone. It is most common in people between the ages of 30 and 60, though most suffer from it in the hip and shoulder. The ultra-rare condition has caused her weight-bearing shin bone to die from lack of oxygen. Doctors have been baffled by the condition, which has never been seen before on a leg bone and usually affects joints. Mum Kerstin said: 'The doctor told her "Hannah, you have to listen to everything I say because even if you go jogging then your leg could collapse into your ankle and that would be the worst thing that could ever happen". 'I think she's dealt with it better than we have as parents. She's been so brave. 'She has such a high pain threshold and her first words to me after her accident were "where've you been and what took you so long?" 'Hannah's a girl of few words but one of the most aggressive centre-backs you'll ever see.' The youngster set records at youth level for Wales - appearing for the under-16s, under-17s and under-19s sides in the space of just eight days - before she was struck down by a freak accident in March 2013. The promising centre-back suffered a sickening dislocation of her ankle and fractured her fibia and tibia after falling while running on astroturf during routine training. Despite the help of Football Association of Wales and Cardiff City physios, the talented star hit a brick road in her recovery and saw specialists in November 2013 when she discovered she had AVN.

Hannah, who is also autistic, has not kicked a ball since and turned her hand to coaching, working with the girls' Under-8s, 10s and 14s at Swansea. Kerstin said: 'Hannah has always had a ball at her feet and played for her first club when she was seven. 'She used to play with the boys until she was 11 and she wasn't happy when she had to stop - she enjoys the rough and tumble.' 'Football is everything for her and she has missed out on the social side because all her friends are at football so she doesn't see them. 'She's had her bad days but we're getting more positive ones now.' Despite two years on the sidelines, Hannah is still dreaming of a senior appearance for the Wales national side and is being followed by Women's Super League side Bristol Academy.

Manchester United supporter Hannah said: 'It would mean everything to get back out on the pitch after two years out - when I play that is when I am most happy in life. 'It's so frustrating having to sit and watch when I just want to be out there playing. 'It's my dream to get a full senior Wales cap and I'd love to go and be a professional player in America too.' The treatment Hannah had been receiving was discovered to have stopped working last month leaving the family with nowhere to turn. In desperation, mum-of-five Kerstin took to Facebook and was amazed when a school friend she had not spoke to for almost three decades got in touch.

The long-lost contact threw the family a lifeline as experts at the world's biggest orthopaedic conference in Las Vegas in the USA ended up analysing Hannah's MRI scan. As a result, Hannah, who lives with brothers Daniel, 23, Thomas, 20, Conor, 16, Ben, 10, and dad Jonathan, 42, as well as Kerstin, has secured an appointment with a leading specialist in London on April 20. Kerstin said: 'She is still training all the time at Swansea City and you should see her upper body now. 'She has a core that puts some of the men to shame when she is in the gym with all of them. 'Hannah's so humble but she can do so many things that even the men there would struggle to do. 'It's been a hard two years for her but she has never given up and she never will do. 'I'm proud of every single breath that girl takes.'
