Acute spinal cord injury: a case-based approach

The presentation

Imagine an adult who has fallen from a height, been thrown in a car crash, or dived into shallow water. Afterwards they complain of severe neck or back pain, and say their arms or legs feel numb, tingling or weak, or that they cannot move them at all. They may have lost control of their bladder or bowels. Some describe a strange electric-shock feeling down the body. This picture — a big impact followed by weakness, numbness or loss of movement below the injury — points to possible spinal cord injury. Warning signs can also include difficulty breathing if the neck is involved. Not every sign is dramatic; even someone who can walk after an accident may still have a spinal injury, so any of these features after significant force must be taken seriously.

Why the spinal cord matters

The spinal cord runs down a canal inside the bones of the spine and acts like the body's main cable, carrying signals for movement, sensation and control of the bladder and bowel. The bony spine protects it, but a heavy blow, a fall or a crash can fracture or shift these bones. The real danger is that broken or unstable bones can press on or tear the delicate cord. Damage high up in the neck affects more of the body, including, in the worst cases, the muscles used for breathing; damage lower down affects the legs and lower body. Unlike a cut that mends, the spinal cord has very little ability to repair itself, so any damage tends to be lasting. This is why preventing further movement after injury is so important — the goal is to stop a bad situation getting worse.

Do not move them — and when to call 999

If you suspect a spinal injury after a serious accident, the safest action is usually to keep the person still and call 999 immediately. Do not move them or try to sit them up unless they are in immediate danger, such as from fire or drowning, because movement can worsen damage to an unstable spine. Reassure them, tell them to keep still, and if you must support the head, hold it gently in line with the body without pulling. Call 999 straight away for any significant head, neck or back injury with pain, numbness, tingling, weakness, loss of movement, or loss of bladder or bowel control. Only move the person if leaving them would put their life at greater risk, and follow the 999 call handler's instructions, who can guide you until the ambulance arrives.

What happens in hospital

In hospital, the priorities are to protect breathing and circulation and to prevent further harm to the cord. The person is kept still with careful support while the team assess them, ask exactly what happened, and test movement and sensation in the arms and legs. Scans such as X-rays and detailed CT or MRI imaging show whether bones are broken or displaced and whether the cord is being pressed on. Treatment depends on the findings: unstable fractures or pressure on the cord may need surgery to stabilise the spine and relieve the pressure, while other injuries are managed with support and close monitoring. Blood pressure and breathing are watched carefully, especially with neck injuries. Early specialist spinal care gives the best chance of protecting whatever function remains and starting recovery on the right footing.

Recovery and the safe pathway

The outlook after spinal cord injury varies widely, from full recovery in milder cases to lasting changes in movement, sensation or bladder and bowel control in more severe ones. Rehabilitation by a specialist team — including physiotherapists, occupational therapists and spinal specialists — is central, helping people regain function, adapt and live as fully as possible. Modern spinal injury centres and support organisations make a real difference. The practical message for everyone is about the first few minutes: after any serious fall, crash or blow to the head, neck or back, if there is pain, numbness, weakness or loss of movement, keep the person still and call 999. Do not move them unless their life is in immediate danger. Acting calmly and protecting the spine early is one of the most valuable things a bystander can do.
