English Abstract:

  【Abstract】 Objectives: To evaluate the clinical outcome and feasibility of one-stage posterior debridement, bony graft, and instrumentation for lumbosacral tuberculosis in adults. Methods: 17 patients suffering from lumbosacral tuberculosis admitted into our hospital between March 2004 and October 2010 and treated by one-stage posterior debridement, bony graft, and instrumentation were reviewed retrospectively. The clinical indexes including the lumbosacral incidence, Frankel grade and ESR were reviewed at follow-up. Results: The average operation time was 145min(130-200min), and the average blood loss was 700ml(500-850ml). The average follow-up period was 47.5±17.1 months(17-71 months). No instrument related complication was noted or neurologic function improved in various degrees. The mean lumbosacral incidence was 20.5±1.7 degrees (18.0-23.0 degrees) before operation and 29.1±1.5 degrees(26.4-31.0 degrees) after operation. The average ESR value before intervention was 57.4±16.8mm/h(33-95mm/h) and reached 9.2±3.1mm/h in 3 months. All patients got bony fusion within 6-8 months after surgery, with 15 Bridwell Ⅰ and 2 Bridwell Ⅱ. Conclusions: One-stage posterior debridement, bony graft and instrumentation is effective and reliable for lumbosacral tuberculosis in adults.
