For a patient with suspected spinal cord injury in the acute setting, initial assessments should follow a prioritising sequence, such as
- General Spinal Injury Assessment:
At all stages, protect the cervical spine with manual in-line spinal immobilisation, especially during airway interventions, and avoid moving the rest of the spine NICE NG41. Assess the patient for spinal injury by checking for:
- Any significant distracting injuries NICE NG41.
- Influence of drugs or alcohol NICE NG41.
- Confusion or uncooperativeness NICE NG41.
- Reduced level of consciousness NICE NG41.
- Any spinal pain NICE NG41.
- Hand or foot weakness (motor assessment) NICE NG41.
- Altered or absent sensation in the hands or feet (sensory assessment) NICE NG41.
- Priapism (in unconscious or exposed males) NICE NG41.
- A history of past spinal problems, including previous spinal surgery or conditions predisposing to spinal instability NICE NG41.
Full in-line spinal immobilisation should be carried out or maintained if any of these factors are present or if the assessment cannot be completed NICE NG41.
- Cervical Spine Injury Assessment:
Assess for cervical spine injury using the Canadian C-spine rule NICE NG41. A patient is considered at high risk if they have at least one of the following:
- Age 65 years or older NICE NG41.
- Dangerous mechanism of injury (e.g., fall from >1 metre or 5 steps, axial load to the head, high-speed motor vehicle collision, rollover accident, ejection from vehicle, motorised recreational vehicle accident, bicycle collision, horse riding accidents) NICE NG41.
- Paraesthesia in the upper or lower limbs NICE NG41.
A patient is considered at low risk if they have at least one of the following:
- Involved in a minor rear-end motor vehicle collision NICE NG41.
- Comfortable in a sitting position NICE NG41.
- Ambulatory at any time since the injury NICE NG41.
- No midline cervical spine tenderness NICE NG41.
- Delayed onset of neck pain NICE NG41.
If low-risk factors are present and there are no high-risk factors, assess if the patient is able to actively rotate their neck 45 degrees to the left and right NICE NG41. If they have low-risk factors and can actively rotate their neck 45 degrees left and right, they are considered to have no risk NICE NG41. Note that applying the Canadian C-spine rule to children can be difficult and their developmental stage should be considered NICE NG41.
- Thoracic or Lumbosacral Spine Injury Assessment:
Assess for thoracic or lumbosacral spine injury using these factors:
- Age 65 years or older with reported pain in the thoracic or lumbosacral spine NICE NG41.
- Dangerous mechanism of injury (e.g., fall from >3 metres, axial load to the head or base of the spine, high-speed motor vehicle collision, rollover accident, lap belt restraint only, ejection from vehicle, motorised recreational vehicle accident, bicycle collision, horse riding accidents) NICE NG41.
- Pre-existing spinal pathology, or known or at risk of osteoporosis (e.g., steroid use) NICE NG41.
- Suspected spinal fracture in another region of the spine NICE NG41.
- Abnormal neurological symptoms (paraesthesia, weakness, or numbness) NICE NG41.
- On examination: abnormal neurological signs (motor or sensory deficit), new deformity or bony midline tenderness (on palpation), bony midline tenderness (on percussion), midline or spinal pain (on coughing) NICE NG41.
- On mobilisation (sit, stand, step, assess walking): pain or abnormal neurological symptoms (stop if this occurs) NICE NG41.
Similar to cervical spine assessment, assessing children for thoracic or lumbosacral spine injury is difficult and their developmental stage should be considered NICE NG41.
- When to Carry Out or Maintain Full In-line Spinal Immobilisation and Request Imaging:
Full in-line spinal immobilisation and imaging should be carried out or maintained if a high-risk factor for cervical spine injury is identified by the Canadian C-spine rule, or if a low-risk factor is identified and the patient is unable to actively rotate their neck 45 degrees left and right, or if indicated by one or more of the factors for thoracic or lumbosacral spine injury NICE NG41.
