Surgical Efficacy and Prognostic Factors for Acute Traumatic Central Cord Syndrome Without Fracture and Dislocation

Abstract

This study was undertaken to evaluate the effectiveness of surgical treatment of acute traumatic central cord syndrome (ATCCS) without fracture and dislocation and explore surgical timing and factors influencing postoperative recovery of spinal cord function. We retrospectively collected the general and clinical data of 112 patients with ATCCS (American Spinal Injury Association impairment scale grade C or D) without fracture and dislocation who underwent surgical treatment in our hospital from January 2013 to August 2019. We used statistical methods to evaluate the safety of the operation and explore the timing of surgery and the factors influencing postoperative recovery of spinal cord function. The mean age of the 112 patients was 60.64±12.91 years. The Japanese Orthopaedic Association score and the American Spinal Injury Association motor score (AMS) of the 112 patients were significantly higher at final follow-up than at admission. No significant difference in recovery of spinal cord function was seen between the early operation group (≤4 days) and the late operation group (>4 days). Comparison of patients with a good prognosis vs a poor prognosis showed that age, intrahand muscle strength at admission, maximum spinal cord compression, maximum canal compromise, length of high-intensity signal in the spinal cord on sagittal T2-weighted magnetic resonance imaging, AMS, and American Spinal Injury Association injury grade D/C at admission had a significant effect on recovery of spinal cord function. Surgical treatment of ATCCS without fracture and dislocation is safe and effective. Age, admission AMS and American Spinal Injury Association impairment scale score, intrinsic hand muscle strength, maximum canal compromise, maximum spinal cord compression, and length of high-intensity signal in the spinal cord can be used to predict postoperative recovery of spinal cord function.
