For many CSI patients, traction may be indicated to help bring the spine into proper alignment and restore blood flow to the injured area. Occasionally, a surgeon may take the patient to the operating room immediately if the cord appears to be compressed by a herniated disc, blood clot, or other lesion. This most often happens with an incomplete SCI or progressive neurologic deterioration. Even if surgery can’t reverse spinal cord damage, it may be needed to stabilize the spine to prevent future pain or deformity.
