Abstract
OBJECTIVES In this study, we assessed the bending strength of two surgical repairs of rib fracture using RibLoc® U Plus system made by Acute Innovations and the anterior plate by Synthes. METHODS After a rib fracture was created in seven pairs of cadaveric rib specimens, one side was repaired with the anterior plate and the other side repaired with the RibLoc U Plus® plate. Each of the rib is loaded using a custom device over 360,000 bending cycles to simulate in vivo fatiguing related to respiration. Upon completion of the cyclic loading, the specimens were compressively loaded to failure and the failure bending moment was determined. RESULTS The ribs repaired with the RibLoc U Plus® system showed 79% higher failure bending moment than that of the anterior plate, with a p value of 0.033. The ribs repaired with RibLoc U Plus® showed a trend of less stiffness reduction over the 360,000 loading cycles. CONCLUSION The biomechanical study showed that the RibLoc U Plus® system is stronger in the bending moment loading of repaired ribs, possibly due to the U-shape structure supporting both the inner and outer cortices of a repaired rib.

Abstract
Objective Rib fixation is an effective treatment for patients with multiple rib
fractures. We retrospectively evaluated the application of a four-claw
titanium plate in patients with rib fractures. Methods Fifty-four patients treated for multiple rib fractures in our hospital from
2012 to 2016 were divided into a surgery group (n = 27) and conservative
treatment group (n = 27). The patients’ age, sex, cause of fracture, Injury
Severity Score, chest Abbreviated Injury Scale score, number of ventilator
days, and length of hospitalization were recorded. Results The mean duration of mechanical ventilation was 4.5 ± 0.7 and 7.9 ± 1.7 days
in the surgery and control group, respectively, with a significant
difference. The length of intensive care unit stay was also significantly
different between the groups (5.9 ± 0.6 vs. 10.6 ± 1.9 days, respectively).
The length of hospital stay and recovery time to regular life in the surgery
and control group were 11.5 ± 1.9 and 3.9 ± 4.0 days and 38.2 ± 8.3 and
60.8 ± 12.1 days, respectively, both with significant differences. Conclusion A four-claw titanium plate is valuable for patients with multiple rib
fractures, allowing easy fixation of broken ribs beneath the scapula, even
the second rib.
