Abstract

Study Design: Retrospective cohort study. Objectives: Combined sternal and spinal fractures are rare traumatic injuries and present a high risk of spinal and thoracic wall instability. Limited research has addressed the treatment of sternovertebral injuries and biomechanical need for sternal fixation to achieve spinal healing. Methods: A 10-year retrospective cohort study was conducted, including patients with sternovertebral fractures admitted to our level-1 trauma centre between 2007 and 2016. Patients who died during hospital admission, military patients, patients with isolated upper cervical spine or lower lumbar spine fractures, and patients lost to follow-up were excluded. Results: In 10 years, 73 patients with sternovertebral fractures were included. Mean injury severity score was 24 (range 4-57). Most sternal fractures were located in the sternal body and manubrium. Spinal fractures were type A (52%), B (40%), or C (8%), and were located in the subaxial cervical (21%), upper thoracic (16%), thoracic (21%), thoracolumbar (47%) area; 7 patients had spinal fractures at multiple levels. Fourteen patients (19%) had a neurological deficit. A total of 42 patients received conservative and 31 patients received operative spinal treatment. Two patients (3%) underwent primary sternal fixation. Sternal failure rate was 1% and biomechanical spinal failure rate was 8%, there was no difference in treatment failure between surgical and conservative spinal treatment. Associated thoracic injuries did not influence sternal or spinal treatment outcomes. Conclusions: These findings indicate that conservative sternal treatment in presence of spinal fractures is safe and effective. The low spinal treatment failure rates imply that sternal fixation is not necessary to achieve spinal stability.
