Sagittal MRI sections showing L3-L4 osteodiscitis (infection of disc and surrounding bone) with erosion of the endplates and disc collapse, with expanding epidural phlegmon (collection of infection putting pressure in the nerves of the spinal canal).
AP and lateral Xrays showing interbody cage placed through a lateral tubular retractor after debridement of the infected disc and bone, and placement of unilateral pedicle screws placed between muscle planes. The interbody cage provides enough stability that only unilateral screws are necessary in this one level fusion, reducing operative time and pain.
