Preclinical assessment of a novel aspirator device for intramedullary bone graft harvesting

Abstract

To repair large bone defects, the patient's own bone material is collected using the Reamer-Irrigator-Aspirator (RIA) system. The RIA system offers a way to extract bone from the inner part of long bones, such as the thigh. However, the RIA system has limitations as it is not very intuitive for surgeons to use and the quality of the bone graft is controversial in the literature. In in vitro and in vivo studies, we have investigated a novel device that aims to simplify and improve the intramedullary bone harvesting process in order to achieve improved outcomes for patients with bone defects
