Treatment for tuberculosis of the subaxial cervical spine: a systematic review

Abstract

Purpose To systematically review the clinical manifestations and treatment outcomes of patients with subaxial cervical spinal tuberculosis (SCS-TB) and evaluate the current evidence for surgical or nonsurgical treatment. Method A systematic review was performed using the PubMed, ScienceDirect, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) databases. Studies published in English from January 2000 to December 2018 were included in the search. A reference lists search of relevant articles was also conducted for other potential references. The risk of bias was assessed with the 13-item criteria recommended by the Cochrane Back and Neck Group and the Methodological Index for Non-Randomized Studies. Results Fifteen articles were included with a total of 456 patients, of which only 1 study was randomized and fourteen were nonrandomized. The most common symptom reported was neck pain and stiffness, and the most common segment involved was C5. Of the 456 patients, 329 (72.1%) were treated surgically. Most experienced neurologic recovery after surgery. Instrumentation resulted in maintenance of the correction of alignment throughout the follow-up period. The use of radical debridement is still in debate. Conclusions Anti-TB therapy is necessary for all SCS-TB patients, including those underwent surgical management. For patients with neurological dysfunction, the surgical method with decompression and instrumentation could provide better cervical spinal alignment and stability. For adult, the radical debridement remains in debate, while for children, radical debridement may cause the development of progressive kyphosis during growth. Larger randomized comparative studies with longer follow-up times are needed.
