Instrumentation following intradural tumor resection: A case analyses and literature review.
Conclusion: Simultaneously performing instrumented fusions following posterior spinal decompressions for tumor removal proved optimal in preventing postoperative spinal deformity. Further, "open" surgical procedures offered more optimal/definitive tumor removal versus minimally invasive approaches, and the greater operative exposure and resultant increased risk for instability were remediated by performing simultaneous fusion.
