In a case involving an anterior cervical discectomy and fusion procedure, the patient suffered a spinal cord injury because the spine surgeon failed to carefully decompress the spinal cord. The surgeon did not use either an operating microscope or magnifying loupes but rather relied on his natural vision. It is generally held as a fundamental principle in the modern era of surgery that the surgeon must use magnified vision and illumination to better visualize the disc and osteophyte pathology at the level of the dura and spinal cord. The removal of disc fragments and osteophytes must be done in such a way as to not press on the dura or spinal cord in such a way that causes injury to the spinal cord or the cervical nerve roots. Sometimes the spinal cord is severely compressed from the underlying pathology and the risks of spinal cord injury are greater than normal however, in every case, great care must be taken to not injure the spinal cord and the nerve roots.
These principles are important in anterior cervical disc surgery and are not meant to be binding on all spine surgeries where the procedures are different.
