Plates versus struts versus an extracortical rib fixation in flail chest patients: Two-center experience

Abstract

Purposes: Notwithstanding advances in medical and surgical management of flail chest, its morbidity and mortality rates are still high. Aim of this study is to compare three approaches for parietal thoracic stabilization by analyzing both early and long-term patient outcomes.

Methods: A retrospective study from January 2006 to January 2018 involving sixty-five surgical flail chest (25 plates,11 struts and 29 wires fixations) was conducted. A mean Abbreviated Injury Scale (AIS) was 2.38±0.82 and a mean Injury Severity Score (ISS) was 32.02±8.21.

Results: Struts and plates stabilizations compared with wires fixation showed an immediate restoring of the partial pressure of oxygen (90.56 mmHg vs 91.90 mmHg vs 89.23 mmHg, p = 0.021), the carbon-dioxide levels (36.00 mmHg vs 35.03 mmHg vs 38.98 mmHg, p = 0.000) and the oxygen-blood saturation (97.71% vs 98.21% vs 92.12%, p = 0.000) in the early postoperative period. Furthermore, struts and plates ensured a better recovery of daily activities up to the 3rdmonth (QoL=1.0: p<0.001 in lateral flail chest and p<0.02 in anterior and antero-lateral flail chest). At the 12thmonth no difference in QoL was found between the different approaches.

Conclusions: Plate and strut fixation revealed a lower rate of postoperative morbidity and mortality. Wires stabilization was characterized for a reduction of operative time.
