Summary
A posterolateral approach is a feasible and effective surgical option for treating irreducible atlantoaxial dislocation (AAD). This technique offers advantages over traditional anterior decompression for irreducible AAD cases.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedic Surgery
Background:
- Anterior decompression via transoral approach is standard for irreducible atlantoaxial dislocation (AAD).
- The transoral approach has known disadvantages.
- Few reports detail the posterolateral approach for irreducible AAD.
Observation:
- A 74-year-old woman with irreducible AAD presented with hemiparesis.
- She underwent odontoidectomy and reduction using a posterolateral approach.
- Posterior fixation with instrumentation and bone graft followed.
Findings:
- Radiological examinations showed satisfactory results.
- The posterolateral approach leverages specific C1-C2 dislocation features in irreducible AAD.
- The procedure was technically feasible and effective.
Implications:
- The posterolateral approach may be a viable alternative for irreducible AAD.
- This technique offers potential advantages for specific AAD presentations.
- Further studies could explore broader application of this approach.
