Synthes RIA System is intended to clear the medullary canal of bone marrow and debris and to effectively size the medullary canal for the acceptance of an intramedullary implant or prosthesis.

The RIA System consists of two types of components; a series of disposable reamer assemblies and reusable drive shafts. The RIA is a device designed for expedited reaming of a medullary canal in preparation of internal fixation. The device includes a free rotating reamer head connected to the distal end of the manifold/tube assembly. The manifold allows both irrigation and aspiration during the reaming process. Irrigation is passed through the cannulation of the reamer and aspiration is drawn from the rear of the flutes in the reamer. The RIA coupled with the Drive Shaft serves as a flexible reaming device and is available in reaming diameters ranging from 9 mm to 24 mm and range in 200 mm to 550 mm in effective reaming lengths.
