It's reported that 10% of the inpatients by traumas have fractured ribs. It's easy to judge if it's the case of flail chest, or respiratory failure due to airway injury or pulmonary contusion. There is no guideline for treatments of a patient who has multiple ribs fractures without respiratory failure. We did the surgical stabilization of rib fractures for 10 cases from 2020 to October 2023. As a result, we find out useful surgical indication for treatment of rib fractures.

In case that met several indication criteria with 4 or more rib fractures, we performed surgical stabilization of multiple fractured ribs using a plate and screw system( Super FIXORB MX) that was made of uncalcined hydroxyapatite (u-HA)/poly-L-lactic acid (PLLA) composite material with excellent bioactivity and absorbability. We report our clinical experience of 7 cases in which this device was used. Although there is still room for further consideration of the technique and the strength of the device itself, computed tomography( CT) images taken 9 months after surgery showed that the fixative device was almost assimilated with the bone at the fracture repair site in cases where fixation was successful.
