Anterior versus posterior instrumentation for treatment of thoracolumbar tuberculosis: Ameta-analysis

BackgroundTo compare clinical and functional outcomes of anterior versus posterior debridement and spinal fixation for surgical treatment of thoracolumbar tuberculosis.MethodsAcomputer-based online search of the Cochrane Library, PubMed, EMBase, Wanfang, VIP, and the CNKI database was performed. The methodological quality of included studies was evaluated, and data analyses were performed using RevMan5.0 software (The Nordic Cochrane Centre, The Cochrane Collaboration Copenhagen, Denmark).ResultsEleven trials were studied, with eight performed in China, two in Egypt, and one in India. The results showed significant differences between the two operative approaches in terms of correction of kyphotic angle and intraoperative blood loss, but not in terms of operation time, hospital stay, fusion time, and loss of correction at the final follow-up.ConclusionThe anterior and posterior approaches are equally good methods for treatment of thoracolumbar tuberculosis. The anterior approach results in less blood loss, whereas posterior instrumentation is better suited for correction of kyphotic angle.
