Open subluxation C2/C3

Last edited: 4/15/2026

Overview

Open subluxation at the C2/C3 level involves an abnormal anterior displacement of C3 relative to C2, often resulting from traumatic injury. This condition can lead to neurological deficits and requires prompt clinical evaluation and intervention 1.

Diagnosis

  • Clinical Presentation: Neck pain, neurological deficits (weakness, sensory loss), and restricted neck movement 1.
  • Imaging: CT or MRI essential for definitive diagnosis, assessing bony alignment and soft tissue injury 1.
  • Grading: Utilize the Anderson and D'Alonzo classification for severity assessment 1.

    • Management

  • Surgical Intervention: Recommended for unstable subluxations or significant neurological deficits 1.
  • Conservative Treatment: Immobilization with a cervical collar, followed by gradual mobilization under neurological monitoring 1.
  • Pain Management: Analgesics (e.g., NSAIDs) for pain control; specific dosing not detailed 1.

    • Special Populations

  • Pregnancy: Management focuses on conservative measures with close monitoring due to altered biomechanics and potential risks of surgery 1.
  • Pediatrics: Conservative treatment preferred initially, with surgical intervention reserved for severe cases due to growth plate considerations 1.
  • Elderly: Increased risk of complications; individualized treatment plans balancing stability and functional outcomes 1.
  • Comorbidities: Tailored approach considering additional health conditions, potentially favoring less invasive treatments 1.

    • Key Recommendations

  • Immediate Imaging: Obtain CT or MRI for definitive diagnosis and assessment of subluxation severity (Evidence: Strong 1).
  • Surgical Consideration: Consider surgical stabilization for unstable subluxations or significant neurological deficits (Evidence: Moderate 1).
  • Conservative Immobilization: Use cervical collars for initial immobilization in stable cases (Evidence: Expert opinion 1).
