Study Design:
A case report and review of the literature.
Objective:
The aim of this study was to describe the successful treatment of one posterior atlantoaxial dislocation without fracture and to review the relevant literature.
Summary Of Background Data:
Posterior atlantoaxial dislocation without fracture of the odontoid process is extremely rare. Management of these patients is still unknown.
Methods:
A posterior atlantoaxial dislocation without fracture in a 58-year-old man with incomplete quadriplegia was treated surgically with posterior atlantoaxial pedicle screws internal fixation and fusion after closed reduction. The images, treatment, and related literature are reviewed.
Results:
The patient had complete recovery of neurologic deficit and bony fusion of the atlantoaxial joint was identified on the follow-up computed tomography taken 3 months after posterior fixation. To our knowledge, no case of posterior atlantoaxial dislocation with neurologic deficit has been previously reported in English medical literature.
Conclusion:
We described a rare case of posterior atlantoaxial dislocation with neurologic deficit. Treatment procedure of posterior atlantoaxial dislocation was presented.
Level Of Evidence:
