The turning point for Marny

Today I recorded a terrific interview for The Limb Shift podcast, launching this October for Amputee Awareness Week!

I spoke with Marny Cringle (who lives near Newcastle), who survived a horrific tube station incident at London’s Green Park in 1996, resuling in an above knee amputation, and some brain damage. After three years of intensive rehabilitation, she returned to nursing—adapting as an above-knee amputee—and even went on to compete internationally in wheelchair tennis.

On 1 December 1996, the life of Australian registered nurse Marny Cringle changed forever in the depths of the London Underground. Having spent two and a half years working in London trauma units and travelling through Europe, her vibrant working holiday came to a catastrophic halt at Green Park tube station. While waiting to catch a train, Marny suffered a horrific accident that resulted in her being run over and dragged by a tube train. The exact mechanics of the incident remain unknown and shrouded in post-traumatic amnesia.

As Marny later recalled in the interview for The Limb Shift podcast:

“I don’t know what happened… I was standing at the end of the platform”.

Investigators and a police colleague surmised that an unlocked platform gate may have swung open and struck her onto the tracks, or her long coat might have caught on the train. Ironically, the ambulance drivers who rushed her from the scene were paramedics she knew personally from her professional work in the hospital trauma unit.

The Physical Toll & Defying the Odds

The physical toll of the accident was catastrophic. Marny suffered:

• Extensive fractures to every bone in her skull
• Several areas of her brain were ripped out by the train
• Her eyes were dislodged
• Her left leg was traumatically removed by the train high above knee
• Broke her back in several places
• Multiple rib fractures with collapsed lungs and other injuries too many to mention.

While fighting for her life unconscious and on life support, she contracted meningitis. Marny’s medical team believed her injuries were completely incompatible with survival, and because of this, her life support was turned off but the pain killers remained to keep her comfortable. When Marny continue to live and breathe independently, she had a delayed closure of her traumatic above knee amputation (AKA) seven days later, the day before her birthday on 8 December 1996.

Defying all clinical expectations, Marny survived. However, she emerged from the trauma with a profound brain injury, twelve weeks of post-traumatic amnesia, and hemiparesis that left the left side of her body severely weakened.

Following three months of acute hospitalisation and intensive physiotherapy in London, Marny returned to Australia, where she spent a year residing in a transitional living unit in Newcastle to recover from her acquired brain injury (ABI) and to regain independent living skills.

Reclaiming Independence & Returning to Nursing

Medical professionals repeatedly cast doubt on her aspirations to reclaim her independent life, warning her that she would never nurse or drive again due to her cognitive impairments and lack of depth perception. Marny refused to accept these limitations. She rebuilt her physical capacity by swimming two kilometres every day to restore her collapsed lungs and drew upon her old knowledge while successfully completing nursing courses.

“Just under three years” after the accident, she successfully returned to her nursing career. Working on crutches, she adapted her clinical environment creatively, using deep storage containers to carry injection dishes and utilizing wheeled trolleys for dressings. Her career post-accident has spanned paediatrics, neonatal intensive care, aged care, medical / rehabilitation nursing and chronic disease management. In her professional life, her lived experience allowed her to connect deeply with other amputees experiencing phantom pain and early surgical recovery.

A World-First Medical Journey

For sixteen years following her accident, Marny was unable to successfully wear a conventional prosthetic limb due to her exceptionally short residual femur, which measured only five centimetres. After years of painful, unsuccessful prosthetic fittings between Newcastle and Sydney, she was introduced to pioneering prosthetic research.

To facilitate aprosthesis, Marny underwent a world-first surgical process to lengthen her residual bone using an external fixator. The procedure required immense grit; she continued working while manually turning a bone-lengthening screw every six hours to stretch the bone a quarter of a millimetre at a time. Once the femur successfully consolidated to the required length, Marny underwent a complex, multi-stage osseointegration procedure that enabled her to use a socket-free bionic leg. It was great to be walking again, but due to not weight bearing for 16 years, she developed stress fractures which meant the procedure had to be repeated and combined with a total hip replacement.

Elite Sports and New Passions

Parallel to her clinical career, Marny remained an avid sportsperson. Before her accident, she was a long-distance runner; afterward, she adapted her athletic pursuits with equal intensity. She excelled in equestrian dressage, won medals at state swimming championships, skied the slopes at Thredbo – first on one leg and later using a sit-ski – and went on to compete at an elite level in wheelchair tennis.

Marny eventually became the number one ranked seeded wheelchair tennis player in Australia, travelling internationally to compete in tournaments across America and Malaysia. In her later years, following hand fractures that limited her ability to grip a tennis racquet, she transitioned to playing wheelchair pickleball. Pickleball is a fast-growing paddle sport that blends elements of tennis, badminton, and table tennis, played on a smaller court with a low net. It uses solid paddles to hit a perforated, hollow plastic ball, making it highly accessible and fast-moving, particularly during close-range doubles rallies near the net.

Sharing Her Message: Small Steps, Big Outcomes

Marny has a book which documents her life experiences and incredible journey of survival, a memoir titled Small Steps Big Outcomes – how to change your circumstances for success.

Through her story, Marny hopes to show that taking small, consistent steps can lead to powerful outcomes. Above all, she wants to encourage others to recognise their own capabilities and realise that we all carry hidden reserves of potential.

Reflecting on her journey she observed that:

“Losing a limb has brought both challenges and unexpected gifts… It has shown me that strength is not measured by what we lose, but how we respond”.

Now aged 56 and temporarily living in a regional area outside Newcastle, Marny continues to navigate the long-term impacts of her injuries with pragmatism and vulnerability. Her daily reality involves a constant effort to manage ongoing physical issues. She recently had to undergo major emergency surgery, an event that left her less active and once again presented a hurdle to her mobility.

True to her nature, she remains determined, learning to use her bionic leg with one stick for a few hours a day and adapting her goals—such as striving to wear her leg for a performance just long enough to carry her violin onto the stage.

As she faces the natural progression of getting older, Marny is candid about the compounding challenges.

“As I’m getting older, things are deteriorating and more problems are arising,” she shared. “And I thought, I just don’t know where it’s going to go from here.”

Despite this uncertainty, her approach to the future focuses heavily on proactive management and meaningful engagement. She places immense value on keeping her mind sharp by playing the violin, sustaining her physical health through sports like pickleball, and nurturing good social connections.

For Marny, ageing means positively managing the structural issues that arise over time, ensuring she remains as healthy, active and connected as possible.

Ultimately, Marny’s path through profound physical and neurological trauma served as the foundation for her work as an inspirational speaker. Her enduring message to others facing profound adversity remains steadfastly optimistic:

“No matter what you have lost, no matter what challenge you face, your story is not over”.
