Summary
Chronic atlantoaxial dislocation treatment varied by reducibility. Successful posterior fusion occurred in 12/13 reducible cases, while transoral surgery achieved reduction in 8/9 irreducible cases, with 4 achieving fusion.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Chronic atlantoaxial dislocation presents complex treatment challenges.
- Skeletal traction and transoral approaches are established methods for managing this condition.
Purpose of the Study:
- To evaluate the efficacy of different surgical strategies for chronic atlantoaxial dislocation based on reducibility.
- To compare outcomes of posterior fusion versus transoral reduction and fusion.
Main Methods:
- Retrospective analysis of 22 patients with chronic atlantoaxial dislocation.
- Treatment categorized by dislocation reducibility: skeletal traction for reducible, transoral approach for irreducible.
- Assessment of surgical success based on reduction and fusion rates.
Main Results:
- Posterior fusion was highly successful (12/13 patients) for reducible dislocations treated with skeletal traction.
- Transoral surgery achieved successful reduction in 8/9 patients with irreducible dislocations.
- Fusion rates varied significantly, with 4/8 successful fusions in the transoral group.
Conclusions:
- Posterior fusion is effective for reducible chronic atlantoaxial dislocations.
- Transoral surgery facilitates reduction in irreducible cases, but fusion remains a challenge.
- Further research may optimize fusion techniques for transoral approaches in irreducible dislocations.
