Last updated May 2017  \n\n| What are the approved indications for the use of the Reamer Irrigator Aspirator system (RIA)?\u003Cbr>Indications for the use of RIA (Fig 1) are:\u003Cbr>• To clear the medullary canal of bone marrow and reaming debris\u003Cbr>• To effectively size the medullary canal for the acceptance of an intramedullary implant or prosthesis\u003Cbr>• To harvest finely morselized autogenous bone and bone marrow for any surgical procedures requiring bone graft to facilitate fusion and/or fill bone defects\u003Cbr>• To remove infected and necrotic bone and tissue from the intramedullary canal in the treatment of osteomyelitis. |\n| --- |\n| What other uses of RIA are described in the literature? The use of RIA has also been reported in the management of impending pathologic fractures [1] . When reaming an intact femur, many surgeons have recommended venting the bone distally in order to minimize the intramedullary pressure production during reaming. With the use of RIA, distal venting may not be necessary since the device is designed to minimize the build-up of pressure during reaming. |\n\nCan I use the RIA in patients with osteomyelitis?  \nYes, the RIA system can be used and may provide some advantage in the debridement of intramedullary infection due to the irrigation and aspiration of the intramedullary cavity [2–4] .  \n\n| Can I use the RIA in oncology patients?\u003Cbr>Yes, RIA can be used in oncology patients. The use of RIA may provide some advantage in decreasing embolization of intramedullary contents [1] . |\n| --- |\n| What materials, in addition to the RIA assembly, are required for the use of RIA?\u003Cbr>Additionally required materials include:\u003Cbr>• 1–2 liter container of irrigation fluid (eg, isotonic 0. 9% NaCl)\u003Cbr>• Irrigation tubing set (“TURP”, cysto-bladder, cystoscopy)\u003Cbr>• 2–5 liter suction container. Because the system will not work properly if the suction canister becomes completely filled, it is therefore helpful to use a large suction canister. It is also important to have an adequate level of suction. Ideally, the RIA suction tubing should be connected to its own dedicated suction device. If other items are attached to the suction source, these should be closed off during the use of RIA to achieve optimal suction\u003Cbr>• Aspiration/suction tubing (minimum 6 mm or ¼ inch diameter)\u003Cbr>• If you wish to harvest intramedullary material for bone graft, the graft filter for RIA (item 352. 229S) is also required. |\n\nWhat type of power is required for the RIA?  \nA power drill that provides 3.5–4.5 Nm of torque and 700–900 RPMs is recommended.  \na b  \nFig 1a-b The Reamer Irrigator Aspirator system (a) with attached power tool (b) .  \n\n| What is the smallest diameter reamer head available? The smallest diameter reamer head is 12 mm. This diameter can be used for reaming the femur in almost all adult patients.\u003Cbr>If preoperative radiographic measurement indicates that the intramedullary diameter is smaller than 11 mm then it may be necessary to initially use standard reamers to enlarge the intramedullary canal to safely accept the 12 mm RIA reamer head. Selecting too large of a reamer head with respect to the intramedullary canal size can place excessive torque on the driveshaft and can lead to breakage of the reamer drive shaft.\u003Cbr>If preoperative radiographic measurement indicates an unusually small canal diameter then RIA should not be used. |\n| --- |\n| What is the largest diameter reamer head available? The largest diameter reamer head is 19 mm. |\n| Can reamer heads be interchanged?\u003Cbr>Reamer heads are not designed to be interchanged in the current RIA system. |\n\nHow do you determine the proper reamer head size?  \nThe diameter of the isthmus is measured on an AP view of the femur (Fig 2) . The AP measurement has been found to be amore accurate measurement of the canal diameter than measurement made on lateral views","cbCaiu9nEJHlUOXX","https://ap.wps.com/l/cbCaiu9nEJHlUOXX","pdf",168787,"English","# Approved indications\n# Additional literature-reported uses\n# Patient eligibility: osteomyelitis and oncology\n# Materials required for RIA use\n# Required power specifications\n# Reamer head sizes and limitations\n# Determining proper reamer head size\n# Verifying correct device assembly\n# Advancement technique\n# Troubleshooting clogging during harvesting","[{\"question\":\"What are the approved indications for using the Reamer Irrigator Aspirator system (RIA)?\",\"answer\":\"RIA is indicated to clear the medullary canal of bone marrow and reaming debris; to size the canal for acceptance of an intramedullary implant or prosthesis; to harvest finely morselized autogenous bone and bone marrow for procedures requiring bone graft; and to remove infected and necrotic bone and tissue in intramedullary canal osteomyelitis treatment.\"},{\"question\":\"Can RIA be used in patients with osteomyelitis, and what advantage is described?\",\"answer\":\"Yes.
