RESUMO
Study Design: A retrospective cohort study. Purpose: To compare the outcomes of anterior decompression with bone grafting alone and anterior decompression with bone grafting and fixation. Methods: 93 patients with minimum 2 year follow-up were included in the study. 50 patients had undergone anterior decompression with bone grafting without instrumentation (group 1) and 43 patients with instrumentation (group 2). Both groups were compared using their demographic data, vertebral level of involvement, neurological recovery and progression of kyphotic deformity. Results: Demographic data and pre-operative parameters were comparable in both groups. The mean (SD) of pre-operative kyphotic angle (in degrees) in group 1 was 29° (8.47°) and in group 2 was 29.81° (9.51°). The mean loss of correction at follow-up was 9.6° for group 1 compared to 3.4° for group 2. The mean loss of correction in patients of group 1 involving upper thoracic spine was 5.6°. There was no significant difference between the two groups across different age groups. Conclusion: Use of anterior instrumentation for decompression surgeries in cases of tubercular spine have shown significantly better results compared to strut grafting alone with respect to restricting the progression of kyphotic deformity at follow-up. Instrumentation may be avoided in patients older than 60 years of age and those involving the upper thoracic spine, more so if both of these co-exist. However, further studies are needed to make our patient selection more rational, so as to avoid the failures and complications of this morbid procedure.
