Abstract:[Objective] To compare the clinical outcomes of anti-tuberculosis chemotherapy combined with or without pedicle screw fixation for GATA type II thoracolumbar tuberculosis. [Methods] A retrospective study was conducted on 67 patients who received treat- ment for GATA type II thoracolumbar tuberculosis in our hospital from May 2017 to July 2019. Among them, 36 patients were treated with anti-tuberculosis chemotherapy alone (conservative group) , while the remaining 31 patients received anti-tuberculosis chemotherapy com- bined with pedicle screw fixation (operation group) . The documents regarding to early stage, follow-up, radiographs and laboratory tests were compared between the two groups. [Results] There was no significant difference in the incidence of early adverse reactions between the two groups (P<0.05) . All the patients were followed up for (33.35±5.23) months, and the operation group resumed full weight-bearing activity significantly earlier than the conservative group (P<0.05) . The VAS score, ODI score, JOA score, and ASIA neurological function grade in the two groups significantly improved over time (P<0.05) . At the corresponding time points after treatment, the surgery group proved significantly superior to the conservative group in terms of ODI and JOA score (P<0.05) , but there was no significant difference in ASIA grades between the two groups (P>0.05) . The incidence of late complications in the surgery group was significantly lower than that in the conservative group (P<0.05) . With regard to auxiliary examinations, the operation group proved significantly superior to conservative group in terms of the local kyphotic Cobb angle and lesion outcome observed on images after treatment (P<0.05) , as well as C-reactive pro- tein (CRP) at 3 months after treatment and erythrocyte sedimentation rate (ESR) at 6 months after treatment (P<0.05) . [Conclusion] Antituberculosis chemotherapy combined with pedicle screw fixation for GATA type II thoracolumbar tuberculosis does significantly relieve the early pain, accelerate rehabilitation, avoid the occurrence of kyphosis, and achieve clinical outcome considerably better than anti-tubercu- losis chemotherapy alone.
