Posterior Sternoclavicular Dislocation: Do We Need "Cardiothoracic Backup"? Insights From a National Sample.

Abstract

To describe the incidence of and risk factors for vascular injury associated with P-SCD. We used data from the HCUP-NIS from 2015 to 2016 and defined a cohort of patients with sternoclavicular dislocation (SCD) using ICD-10-CM diagnosis codes. We further isolated a subset with P-SCD. We describe the incidence of thoracic vascular injury, demographics, and injury severity score in this cohort. Of an estimated 550 patients who had SCD, 140 (25%) were identified as having a P-SCD. No vascular injuries occurred in the P-SCD cohort. Among all patients with SCD, <2% of patients had a vascular injury, all of whom had an injury severity score ≥15, independent of the vascular injury itself. Among patients with an isolated P-SCD injury (55), overall length of stay was 1.8 days and total charges averaged $29,724.45. There was no mortality among patients with isolated P-SCD. Here, we report no vascular injuries in the largest known series of P-SCD. Among all patients with SCD, vascular injury was rare, occurring only in severely polytraumatized patients. The recommendation for routine involvement of cardiothoracic surgeons in all cases of P-SCD should be re-examined. Prognostic Level III.
