Short-Term Outcome in Subaxial Spine Injury Patients Operated on in a Resource-Limited Setting, Addis Ababa, Ethiopia

Abstract

Background: Subaxial spinal injury surgery is expensive, and its significance is uncertain because of limited rehabilitation and postoperative care.

Objective: To assess complications and outcome in patients surgically treated for subaxial spinal injuries in 2 hospitals in Addis Ababa, Ethiopia.

Methods: Retrospective study, conducted among 85 patients operated on for subaxial spine injury from January 2013 to August 2016. Data were collected from medical charts. Descriptive statistics and binary logistic regression were used for data analysis.

Results: A total of 85 patients were included, and 20 patients were not followed up. The mean age was 33 years (standard deviation ± 12.03 years), and the mean time from injury to surgery was 10 days. The rates of surgical mortality and reoperation were 7.05% and 3.5%, respectively. Deaths occurred in 13 of 16 patients (81.1%) with American Spine Injury Association (ASIA) scores of A and in 3 of 16 patients (18.9%) with ASIA scores of B. The complication rate in patients with a preoperative ASIA score of A was 17/24 (70.8%). The study showed that 55 of 65 patients who were followed up (84.6%; 95% confidence interval [CI]: 75.4, 92.3) experienced improvement. According to the patients' follow-up ASIA scores, 47 (72.3%; 95% CI: 61.5, 83.1) were functional. Sphincter tone before operation (adjusted odds ratio 142.82; 95% CI: 9.973, 204.090) was significantly associated with follow-up ASIA score.

Conclusions: Patients with complete cervical injuries had high rates of mortality and morbidity, indicating that it might be better not to operate on these patients in resource-limited settings. There is a moderate recovery rate in patients with incomplete SCI despite a lack of adequate rehabilitation facilities.
