Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Spinal Fusion Techniques

Background:

  • Posterior atlantoaxial arthrodesis is crucial for stabilizing traumatic axis conditions.
  • Traditional methods may involve prolonged immobilization and potential complications.
  • Addressing nonunion of odontoid peg fractures and atlantoaxial dislocations requires effective surgical solutions.

Purpose of the Study:

  • To describe a simplified posterior atlantoaxial arthrodesis method.
  • To evaluate the efficacy and safety of this technique in a clinical setting.
  • To highlight the benefits of immediate mobilization and cost-effectiveness.

Main Methods:

  • A simplified posterior surgical fixation technique for atlantoaxial arthrodesis was employed.
  • The method was applied to 33 patients with indications including odontoid peg fracture nonunion and atlantoaxial dislocation.

  • Follow-up assessments focused on fusion rates and complication incidence.

    • Main Results:

    • All 33 patients achieved solid bony fusion by 3 months postoperatively.
    • The surgical technique demonstrated minimal complication rates.
    • Immediate postoperative mobilization was successfully achieved in all cases.

    Conclusions:

    • This simplified posterior atlantoaxial arthrodesis is a safe and effective treatment option.
    • The technique allows for early patient mobilization, reducing associated risks.
    • It provides robust stabilization, controls rotational and lateral movements, and is economically viable.
