Composition of Reaming Products in Relation to Reaming Drill Diameter

Abstract

The change of substance of reaming products in the different grades of reaming were examined. Intramedullary bone reamings were obtained from the tibia or femur of thirty-nine patients during intramedullary nailing procedures. Histological examination in paraffin sections showed that the main substance of reaming products were viable, non-viable bone trabeculae and bone marrow elements. Statistical analysis of these histological findings depending on the different grades of reaming revealed that reamer diameter correlates with the percentage of viable and non-viable bone mass. Preoperative planning in intramedullary nailing procedures can provide a good source of bone graft material only with a careful estimation of the medullary canal diameter.
