Assessing Cardiopulmonary Safety of Intramedullary Bone Graft Harvesting: A Comparative Study of the RIA 2 System and the ARA Concept.

ABSTRACT: The management of large osseous defects requires innovative intramedullary bone graft harvesting techniques to optimize healing while minimizing complications. Intramedullary bone graft harvesting is, however, associated with potential cardiopulmonary adverse events due to embolic phenomena and systemic inflammation. This study compares the newly introduced aspirator + reaming-aspiration (ARA) concept with the established second-generation Reamer-Irrigator-Aspirator (RIA 2) system, focusing on cardiopulmonary safety in a non-fracture sheep femur model. Sixteen female Merino sheep underwent intramedullary bone grafting using either the RIA 2 system or the ARA concept. The primary outcomes measured were blood loss, hemodynamic parameters, pulmonary function via the Horovitz index, and system
