 Residual disc fragments were drilled away as drilling extended into normal cortical and cancellous elements in order to perform a wide decompression all the way posteriorly to the spinal canal itself finally revealing a ligament, which was removed in a similar piecemeal fashion with 1 and 2-mm micro Kerrison rongeurs also utilizing these instruments to remove prominent osteophytes, widely laterally bilaterally at each interspace with one at C4-C5, more right-sided.
