Synopsis
Localise spinal disease from tract, segmental and autonomic findings, recognise classic incomplete cord patterns and use the neurological level to direct urgent imaging without overclaiming anatomical precision.
- A spinal-cord syndrome combines upper-motor-neurone dysfunction below a lesion, segmental lower-motor-neurone signs at the level, a tract-pattern sensory disturbance and possible autonomic impairment.
- The perceived cutaneous sensory boundary can sit several segments below the structural lesion, especially for pain and temperature, so it guides but must not narrowly limit imaging.
- Corticospinal fibres have crossed in the medulla and descend ipsilaterally, so a hemicord lesion causes ipsilateral pyramidal weakness below the lesion.
Key red flags
Motor and all sensory modalities are absent below the neurological level with no sacral sensory or motor preservation after spinal shock and confounders are considered.
Investigation priorities
Define the most caudal normal motor and sensory segments, sacral sparing and an incomplete-syndrome pattern.
Management branches
A new truncal sensory boundary accompanies bilateral weakness or autonomic symptoms.
- Use ABCDE, check respiratory mechanics for cervical disease, document motor, sensory and sacral status and immobilise if trauma or instability is possible.
- Arrange emergency MRI and spinal advice, using pain, fever, cancer, trauma, anticoagulation and onset tempo to prioritise compression, abscess, haematoma and infarction.
Key medicines
No syndrome-wide drugThere is no single medicine regimen for a sensory level; treatment follows the identified cause.
Cause-directed corticosteroidUse only the relevant metastatic or inflammatory specialist protocol after urgent structural and infectious assessment.
