Background:
Posterior only surgery has been widely performed in the treatment of thoracic and lumbar spinal tuberculosis. Surgical options include debridement with posterior instrumentation only or combined with anterior reconstruction. The aim of this study is to investigate and compare the clinical, functional and radiological outcomes using a single-stage posterior only surgery in thoracolumbar spinal tuberculosis by three different surgical techniques.
Methods:
Patients undergoing posterior only surgery for thoracic and lumbar spinal tuberculosis were followed up prospectively and included. Three different procedures, Group-A: Posterior instrumentation with anterior cage reconstruction (n = 49), Group-B: Posterior instrumentation and anterior autologous bone-grafting (n = 21) and Group-C: Posterior column shortening without anterior-reconstruction (n = 52) were compared for kyphosis correction achieved, kyphosis at final follow-up and degree of correction lost. Neurological assessment was done using ASIA impairment Scale(AIS) grades. Functional assessment was done using Visual analogue score (VAS), Modified McNab criteria and NASS satisfaction score.
Results:
A total of 122 patients were included in the study, Group-A (49), Group-B (21) and Group-C (52). Radiological correction of kyphotic deformity in anterior reconstruction, Group-A (20.17 ± 9.25⁰) was higher than 13.97⁰ ± 6.06⁰ and 14.27⁰ ± 6.47⁰ achieved in Groups B and C respectively. There was no significant difference in correction lost amongst the three groups (p-value, 0.76). Surgical duration, blood loss and hospital stay were significantly higher in the anterior reconstruction group (p-value, 0.001). Similarly, no significant difference was noted between the three groups in neurological and functional outcomes at 2 years.
Conclusion:
Posterior only approach is eminently satisfactory for treating Thoracolumbar Spinal Tuberculosis (STB). All three groups had similar functional and neurological outcomes. However there was a better correction of deformity in patients with anterior cage reconstruction.
