Improved chest wall trauma taxonomy: an interdisciplinary CWIS and ASER collaboration.

PURPOSE: Chest wall injury taxonomy and nomenclature are important components of chest wall injury classification and can be helpful in communicating between providers for treatment planning. Despite the common nature of these injuries, there remains a lack of consensus regarding injury description. The Chest Wall Injury Society (CWIS) developed a taxonomy among surgeons in the field; however, it lacked consensus and clarity in critical areas and collaboration with multidisciplinary partners. We believe an interdisciplinary collaboration between CWIS and American Society of Emergency Radiology (ASER) will improve existing chest wall injury nomenclature and help further research on this topic. METHODS: A collaboration between CWIS and ASER gathered feedback on the consensus recommendations. The workgroup held a series of meetings reviewing each consensus statement, refining the terminology, and contributing additional clarifications from a multidisciplinary lens. RESULTS: After identifying incomplete definitions in the CWIS survey, the workgroup expanded on and clarified the language proposed by the survey. More precise definitions related to rib and costal cartilage fracture quality and location were developed. Proposed changes include more accurate characterization of rib fracture displacement and consistent description of costal cartilage fractures. CONCLUSIONS: The 2019 consensus survey from CWIS provides a framework to discuss chest wall injuries, but several concepts remained unclear. Creating a universally accepted taxonomy and nomenclature, utilizing the CWIS survey and this article as a scaffolding, may help providers communicate the severity of chest wall injury accurately, allow for better operative planning, and provide a common language for researchers in the future.
