Timing of Surgery

General Principle

  • Timing driven by:

    • Neurological status

    • Mechanical instability

    • Ongoing neural compression

Age does NOT change core indications

Early Surgery (<24 hours)

Indications:

  • Incomplete spinal cord injury

  • Progressive neurological deficit

  • Persistent cord / cauda equina compression

  • Unstable injury (translation, distraction, PLC disruption)

Goal:

  • Decompression + stabilisation

  • Prevent secondary injury

Early (24–72 hours)

Indications:

  • Neurologically stable but:

    • Unstable fracture

    • Progressive deformity

    • Polytrauma (after initial stabilisation)

Goal:

  • Early fixation → mobilisation + ICU care

Delayed Surgery

Indications:

  • No neurological deficit

  • Stable injury

  • No significant compression

  • Medical optimisation required

Pediatric-Specific Points

  • Same principles as adults BUT:

    • More ligamentous injuries

    • Higher risk of SCIWORA

    • MRI more important

Surgery considered if:

  • Instability

  • Progressive neuro deficit

  • Failure of conservative care

Quick Algorithm

Neuro deficit + compression → <24h surgery
Unstable (no neuro) → 24–72h surgery
Stable + no neuro → conservative / delayed

Pits & Pearls

  • Early (<24h) decompression = best evidence in incomplete SCI

  • Stability + neurology > fracture type

  • Pediatric CT may look normal → MRI changes decision

  • Early fixation improves mobilisation & care

Pitfalls

  • Delaying surgery in progressive deficit

  • Ignoring ligamentous instability (esp. pediatric)

  • Operating unstable polytrauma too early

  • Treating timing as “fixed hours” instead of clinical decision
