Abstract
STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the functional, neurological and radiological outcomes of posterior trans-facetal decompression and stabilisation in tuberculous spondylodiscitis patients with neuro-deficit. OVERVIEW OF LITERATURE: Spinal tuberculosis mainly involves anterior column and for that anterior approach has been the most frequently used surgical technique in the past as it allows direct access to the infected tissue providing a good decompression. However, anterior surgery is associated with higher morbidity which can be reduced by posterior trans-facetal approach. MATERIALS AND METHODS: The study included 100 Tuberculous Spondylodiscitis patients with neuro-deficit who underwent posterior trans-facetal decompression and stabilisation from 2009 to 2014. Demographic data, clinical parameters (back pain score-VAS, ODI), neurological status (Frankel's grade), radiological parameters (Kyphosis angle) and complications were evaluated. RESULTS: Out of the total 100 patients there were 58 males and 42 females. 84 patients had thoracic and 16 had thoracolumbar region involvement. The mean age of the patients was 34.7 years. The extent of fixation was 2 segments in 52 patients and >2 segments in 48 patients. Postoperatively significant improvement in VAS (pre-op 6.5 ± 0.65 to post-op 1.73 ± 0.64) and ODI (pre-op 76.54 ± 6.96 to post-op 30.5 ± 6.56) were noted. The mean kyphosis angle was corrected from 22.33° ± 5.59° to 5.14° ± 1.32°. 86 patients showed at least 1 grade of improvement in neurology (Frankel's grading) and there was no deterioration in any patient. 3 patients developed superficial infection and 2 had an intra-operative dural tear. 94 patients showed bony fusion at 2 years follow-up. CONCLUSION: Posterior trans-facetal decompression and stabilisation is an effective procedure in the management of thoracic & thoracolumbar tuberculous spondylodiscitis patients with neuro-deficit. It offers circumferential decompression with stabilisation and also maintains kyphosis correction.
