Trends in Spinal Surgery for Pott’s Disease (2000-2016): An Overview and Bibliometric Study

Abstract

Study Design: Systematic review. Objectives: (1) What are the surgical indications? Have they changed over time since the year 2000? (2) What is the current surgical approaches of choice? Have they changed over time since the year 2000? Do they vary by geographical region? (3) What are the most common outcome measures following surgery? Methods: Electronic databases and reference lists of key articles were searched from database inception from January 1, 2000 to December 31, 2016 to identify studies specifically evaluating surgical indications, current surgical approaches, and outcome measures for spinal tuberculosis. Results: Six randomized controlled trials were identified from our search (1 excluded: no surgical arm identified after review) Neurological deficit, instability and deformity were common indications identified. Surgical approach included predominantly anterior for cervical spine and posterior for thoracic and lumbar spine. Combined approach was preferred in pediatric cases. Degree of deformity correction, neurological outcomes, and fusion formed the main bases of assessing surgical outcomes. Conclusions: Majority of the current literature is from South Asia. The presence of neurological compromise, deformity, and instability were the primary criteria for surgical intervention. The preferred approach varied with the anatomical region of the spine in adults. Outcome measures predominantly involved deformity correction, neurological deficit, and fusion.
