Objective: To investigate the qualitative diagnosis method of atlanto-axial tuberculosis and the corresponding therapeutic strategy.
Methods: Twenty-two cases with atlanto-axial tuberculosis proven by histopathologic diagnosis were observed. Three cases and 17 cases underwent trans-oral biopsy and CT-guide percutaneous biopsy respectively, 2 cases were conformed by frozen section in operation. Thirteen of the 22 cases underwent surgical therapy: 1 case with anterior trans-oral radical eradication and fusion under Halo-vest immobilization, 7 cases with anterior cervical radical eradication, 1 case with anterior interbody fusion and titanic plate fixation, 2 cases were with posterior atlantoaxial interlaminar fusion and 2 cases with posterior cervical occipito-axial titanic plate internal fixation and fusion. Other 9 cases accepted nonsurgical therapy: 8 cases with Halo-vest immobilization and 1 case with head halter traction. All cases were given appropriate antituberculotic chemotherapy for 12-18 months.
Results: All of the 22 cases were followed up, and the average time was 37 month. The lesion focus showed reparation and fusion in X-ray, and the results were satisfactory.
Conclusions: Biopsy can acquire the qualitative diagnosis on atlanto-axial tuberculosis. The choice of therapy is made on the situation of cold abscess, pathological fracture, atlanto-axial dislocation and spinal cord compression.
