Neurological Recovery Following Surgical Intervention in Patients with Traumatic Spinal Cord Injury at the University Teaching Hospital in Zambia

Abstract

Introduction Traumatic spinal cord injuries cause long-term disability and functional impairment. Timely and proper surgical treatment improves neurological recovery and functional outcomes. However, in low-resource setting countries, surgical intervention is usually delayed raising concerns about the recovery of patients. Hence, this study investigated the neurological improvement of patients undergoing surgery for traumatic spinal cord injuries at the University Teaching Hospital in Lusaka, Zambia. Methods This was a retrospective study that included all eligible patients with traumatic spinal cord injury managed surgically at the University Teaching Hospital between 2018 and 2022. The study assessed neurological improvement by comparing the American Spinal Injury Association’s neurological grading before surgery to that at discharge. Data was analysed using Stata 17, and the level of significance was set at 5%. Results Out of the 96 patients in the study, 45.8% showed neurological improvement of at least one grade after surgery. Patients with thoracic injuries showed lower improvement rates (25.0%) than those with cervical (55.0%) or lumbar injuries (65.0%), while those with incomplete injuries showed higher improvement rates (78.7%) (p <0.05). Thoracic injuries were associated with reduced neurological improvement (AOR 0.21; 95% CI: 0.04 – 0.95, p = 0.043), while incomplete injuries were associated with higher neurological improvement (AOR 18.58; 95% CI: 6.11 – 56.51, p < 0.001). Conclusion Neurological improvement was poor for thoracic injuries and complete injuries, highlighting the necessity for further investigation into the specific structural features and mechanisms of injury that contribute to poor neurological improvement in thoracic injuries and the identification of effective recovery approaches for these patients.
