ABSTRACT
STUDY DESIGN: A retrospective cohort study.
OBJECTIVE: To identify factors associated with minimally invasive surgery (MIS) utilization and compare inpatient outcomes between MIS and open fusion for traumatic thoracic vertebral fractures using a multicenter trauma registry.
SUMMARY OF BACKGROUND DATA: MIS is increasingly utilized in spine surgery due to its potential to reduce perioperative morbidity. However, its role in managing traumatic thoracic vertebral fractures remains unclear, and large-scale comparisons of MIS versus open fusion in this setting are limited.
METHODS: Adult patients (≥18 y) who underwent thoracic fusion for traumatic thoracic fractures between 2019 and 2021 were identified from the American College of Surgeons Trauma Quality Program database using ICD-10 codes. Patients were stratified by surgical approach (MIS vs. open), and demographic, injury, and clinical characteristics-as well as inpatient outcomes-were compared using chi-squared and t-tests. Multivariable logistic regression was performed to identify patient and injury factors associated with MIS utilization. A P-value < 0.05 was considered statistically significant.
RESULTS: Of 8999 patients undergoing thoracic fusion, 370 (4.1%) received MIS. MIS utilization was associated with older age, lower Injury Severity Scores, and less severe neurological impairment. The number of vertebral levels fused did not differ by approach. MIS patients had significantly shorter length of stay, higher home discharge rates, and lower rates of complications, intensive care unit admission, and mechanical ventilation.
CONCLUSION: This multicenter cohort study identifies key patient and injury characteristics associated with MIS utilization in thoracic trauma. While MIS was associated with some favorable inpatient outcomes, this may be due to selection bias rather than procedural effect. Further prospective studies are needed to clarify appropriate indications and long-term outcomes.
