Management of CVJ tuberculosis: the changing paradigm

摘要

Background The literature seems fractured for the management of craniovertebral junction (CVJ)-tuberculosis (TB). Presently, non-surgical management has been in vogue for neurologically intact patients. On the contrary, severely disabled cases of CVJ-TB continue to attract discussion, tilted towards surgical intervention. We present our experience with the non-surgical management of CVJ-TB tailored to their neurological status. Methods Authors managed 37 cases (2004-2019; age 1-57 years, mean 36 years) of CVJ-TB, of which eighteen (18/37, 48.6%) were severely disabled (Nurick grade >= 3) with a mean follow-up of 84 months (48-192 months). Irrespective of the clinical status and radiological findings, all patients were managed on medical management only. Needle aspiration established pathology in 23 (62.2%) cases, while 9 (24.3%) cases required drainage of an abscess. All patients received 18 months of anti-tubercular therapy (ATT). In patients with Nurick grade >= 3 and documented AAD, we applied halo vest for 12 months to achieve cervical immobilization. Only hard cervical collar for 3 months was prescribed in patients with no documented AAD. Results All minimally disabled cases (Nurick grade = 3,n= 18), 16 cases had favorable outcomes with only external orthosis (12) and 18-month ATT. One patient succumbed to multiple cerebral infarcts, while one required realignment surgery at CVJ due to fusion in malaligned position. Conclusion The authors conclude that the disability grading of CVJ-TB is pertinent only for assessing the functional disability of patients at presentation, with minimal relevance in deciding its management strategy. Irrespective of neurological disability, almost all patients respond favorably to external immobilization and ATT.
