We report a case of symptomatic heterotopic bone formation following lumbar spinal revision surgery and posterolateral fusion with rhBMP-2, successfully treated using a minimally invasive tubular approach and provide documentation of the technical aspect of the procedure. In light of the absence of significant low back pain, the predominance of radicular symptoms, the absence of mechanical instability and the presence of bilateral facet arthrodesis, as well as the history of previous lumbar surgeries and associated medical comorbidities, we felt a minimally invasive approach was an appropriate option to be selected in this case and the patients concurred with this informed decision. In the presented case we found the use of minimally invasive techniques to be of benefit for the removal of heterotopic bone formation following lumbar spine fusion with rhBMP-2.	./cache/cord-253318-nlk8pjv2.txt	./txt/cord-253318-nlk8pjv2.txt
