Novel Application of a New Lateral System for Adjacent-level Revision Surgery: A Case Report.

In recent years, lateral lumbar interbody fusion (LLIF) has grown in popularity as a minimally invasive spine surgery (MISS) approach that can be offered to patients with prior surgeries from a posterior approach. In this report, we present a patient with a focal disease and a history of multiple posterior lumbar surgeries who underwent LLIF with a novel application of the Duo system (Spineology Inc., MN, USA) adjacent to prior surgical levels and without posterior instrumentation. At one year postoperatively, she continued to have no back pain or complaints relating to her lumbar pathology. The case demonstrates the novel use of a new MISS LLIF system that requires minimal exposure as compared to current LLIF systems to treat a patient with adjacent segment disease and progressive symptoms following multiple posterior decompressive surgeries.
