ABSTRACT
<p><b>OBJECTIVE</b>To retrospectively analyze the surgical methods and its clinical effects and explore a clinical classification and treatment strategy for atlantoaxial dislocation(AAD).</p><p><b>METHODS</b>The clinical data of 89 patients with atlantoaxial dislocation were analyzed from September 2005 to September 2013. There were 49 males and 40 females, aged from 13 to 67 years with an average of 48.1 years. According to the reductive effects with preoperative cervical dynamic radiograph and high weight skeletal traction under general anesthesia, the dislocations were classified into three types:easy reduction type, hard reduction type and irreducible type. The patients with easy reduction type were treated with posterior screw rod internal fixation after manual reduction, while the patients with hard reduction type were treated with posterior screw rod fixation after high weight skeletal traction reduction under general anesthesia. The patients with irreducible type were treated with transoral atlantoaxial joint release or depression and posterior internal fixation and fusion. According to JOA scores to evaluate the neurological status and treatment outcome.</p><p><b>RESULTS</b>Thirty patients were classified as easy reduction type, 55 patients as hard reduction type, and 4 patients as irreducible type. The preoperative JOA score was 8.2±3.1 on average, while the postoperative score was 14.2±2.4. The improvement rate was 40.1% to 82.5% with an average of 62.5%. Eighty nine patients were followed up from 6 to 37 months with a mean of 17.3 months. Eighty two cases obtained anatomical reduction and 85 cases obtained bony fusion. One case complicated with hyponatremia after operation and 1 case combined with Guillain-Barre syndrome, 4 cases complicated with delayed union wounds, 1 case died of for respiratory failure 2 years after operation. No wound infections were found in the patients approach for transoral operation.</p><p><b>CONCLUSIONS</b>According to the cervical dynamic radiograph and high weight skeletal traction under general anesthesia to classify for atlantoaxial dislocation, and adopting well strategies to treat the patients, can achieve satisfactory effects.</p>
