Current treatment and outcomes of traumatic sternal fractures-a systematic review.

PURPOSE: Traumatic sternal fractures are rare injuries. The most common mechanism of injury is direct blunt trauma to the anterior chest wall. Most (> 95%) sternal fractures are treated conservatively. Surgical fixation is indicated in case of fracture instability, displacement or non-union. However, limited research has been performed on treatment outcomes. This study aimed to provide an overview of the current treatment practices and outcomes of traumatic sternal fractures and dislocations. METHODS: A systematic review of literature published from 1990 to June 2017 was conducted. Original studies on traumatic sternal fractures, reporting sternal healing or sternal stability were included. Studies on non-traumatic sternal fractures or not reporting sternal healing outcomes, as well as case reports (n = 1), were excluded. RESULTS: Sixteen studies were included in this review, which reported treatment outcomes for 191 patients. Most included studies were case series of poor quality. All patients showed sternal healing and 98% reported pain relief. Treatment complications occurred in 2% of patients. CONCLUSIONS: Treatment of traumatic sternal fractures and dislocations is an underexposed topic. Although all patients in this review displayed sternal healing, results should be interpreted with caution since most included studies were of poor quality.

Current treatment and outcomes of traumatic sternovertebral fractures: a systematic review.

PURPOSE: Combined sternal and spinal fractures are rare traumatic injuries with significant risk of spinal and thoracic wall instability. Controversy remains with regard to treatment strategies and the biomechanical need for sternal fixation to achieve spinal healing. The present study aimed to assess outcomes of sternovertebral fracture treatment. METHODS: A systematic review of literature on the treatment of traumatic sternovertebral fractures was conducted. Original studies published after 1990, reporting sternal and spinal healing or stability were included. Studies not reporting treatment outcomes were excluded. RESULTS: Six studies were included in this review, with a total study population of 98 patients: 2 case series, 3 case reports, and 1 retrospective cohort study. 10 per cent of sternal fractures showed displacement. Most spinal fractures were located in the thoracic spine and were AOSpine type A (51%), type B (35%), or type C (14%). 14 per cent of sternal fractures and 49% of spinal fractures were surgically treated. Sternal treatment failure occurred in 5% of patients and biomechanical spinal failure in 8%. There were no differences in treatment failure between conservative and operative treatment. CONCLUSION: Literature on traumatic sternovertebral fracture treatment is sparse. Findings indicate that in most patients, sternal fixation is not required to achieve sternal and spinal stability. However, results of the current review should be cautiously interpreted, since most included studies were of poor quality.

No Need for Sternal Fixation in Traumatic Sternovertebral Fractures: Outcomes of a 10-Year Retrospective Cohort Study.

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.

Traumatic Sternal Fractures can be Safely Treated Conservatively - A 13-Year Retrospective Cohort Study.

Background: Traumatic sternal fractures are rare injuries with little evidence supporting the best treatment strategy. This study assessed treatment outcomes from our level-I trauma centre. Methods: A retrospective cohort study was conducted, including all sternal fracture patients admitted to our level-I trauma centre between 2007 and 2019. Patients with sternal fractures due to cardiopulmonary resuscitation, patients <16 years, patients who died during initial hospital stay, and patients lost to follow-up were excluded from analysis. Results: In 13 years, 355 patients with traumatic sternal fractures were admitted, corresponding to 2% of all trauma patients. 262 patients were included in analysis. Mean age was 52 years and 71% of patients were male. Mean ISS was 19 (range 4-66). The majority of sternal fractures was located in the sternal body. Six patients (2%) underwent primary sternal fixation. Treatment failure occurred in three patients (1%) and was significantly higher in the surgical treatment group (p=0.001). There was no difference in treatment failure between patients with and without concomitant spinal fractures. Conclusions: Conservative treatment is safe and effective for traumatic sternal fractures. Surgical treatment should be reserved for rare cases, such as imminent respiratory failure or debilitating symptomatic non-union.
