Improved Fixation Stability of a Dedicated Rib Fixation System in Flail Chest: A Retrospective Study.

Background and Objectives : Flail chest typically results from major trauma to the thoracic cage and is accompanied by multiple rib fractures. It has been well documented that surgical fixation of rib fractures can decrease both morbidity and mortality rates. This study aimed to evaluate the effectiveness of a dedicated APS Rib Fixation System, which features a pre-contoured design based on anatomical rib data of the Asian population. Materials and Methods : We reviewed 43 consecutive patients, who underwent surgical stabilization for flail chest with the traditional Mini bone plate ( n = 20), APS plate ( n = 13), or Mini + APS ( n = 10). Demographic and injury variables were documented. We used X-ray radiography to determine plate fractures and screw dislocations after surgical fixation. Results : No statistical differences were noted in the demographic or injury variables. APS plates demonstrated fewer cases of plate fractures and screw dislocations than Mini plates (OR = 0.091, p = 0.008). Conclusions : The pre-contoured design of the APS plate demonstrated a superior rib implant failure rate as compared to the traditional Mini bone plate. Our study indicates that the APS plate may serve as an effective surgical tool for the treatment of flail chest.
