RIA 2 (REAMER IRRIGATOR ASPIRATOR)
Introduction
The RIA 2 System is designed for reaming of the medullary canal for preparation of internal fixation,
harvest of bone and bone marrow, and/or clearing of debris. The RIA 2 System consists of disposable
Reamer Heads, Tube Assembly, Reaming Rod Seal, Graft Filter, Irrigation and Aspiration Tubes, and
reusable Drive Shaft. Ports in the handle of the Tube Assembly allow both irrigation and aspiration
through the Tube Assembly during the reaming process. Irrigating fluid is passed through the cannula
of the Drive Shaft and the Reamer heads. The aspiration fluid is drawn through the Tube Assembly
and out through the Aspiration Tube. The disposables are offered in sterile procedural kits without
the Reamer Head. Assorted sizes of the Reamer Head are offered in individual sterile packs.

1. SELECTION OF THE APPROPRIATE RIA 2 KIT
03.404.000S RIA 2 Bone Harvesting Kit, 520 mm, sterile
03.404.001S RIA 2 Reaming Kit, 520 mm, sterile
Select the appropriate RIA 2 kit based on procedure type.
For bone harvesting procedure, use the RIA 2 Bone Harvesting Kit, 03.404.000S
For reaming only procedure, use the RIA 2 Reaming Kit, 03.404.001S
2. REAMER HEAD SIZE SELECTION
Instrument
351.717 Depth Gauge (radiographic ruler)
Or
03.010.023 Radiographic Canal Width Estimator for IM nails
To estimate the canal diameter, position the image intensifier for an AP view of
the limb at the level of the isthmus. Hold the radiographic ruler perpendicular
to the limb and overlay the diameter tabs over the isthmus. Read the diameter
on the tab that fills the canal. Repeat with an ML view.
CAUTION:
The distance of the radiographic ruler from the bone and the position
of the C-arm receiver affect the image magnification and thus the
diameter measurement.
For bone harvesting, select a Reamer Head up to 1.5 mm larger than the canal
diameter at the isthmus.
When reaming to prepare the intramedullary canal for an implant, choose the
appropriate implant diameter first. Select a Reamer Head based upon the nail
manufacturer’s recommendation.
PREPARATION
NOTE:
Always place the radiographic
ruler on the side of the limb
closest to the C-arm receiver.
Estimate the width as follows:
Distance between radiographic
ruler and bone
a. 25 mm = 1 mm larger reading
b. 50 mm = 2 mm larger reading
c. 100 mm = 3 mm larger reading
Measure in both AP and ML view.
Pre-operative images can also
be used for canal size reference.

Open the medullary canal and conduct reaming by following AO reaming
techniques for IM nailing and maintain a guide wire entry angle of less than
10° from the axis of the canal.
CAUTION:
If the guide wire entry angle is greater than 10° from the axis of the
canal, there is a risk that bowing of the reaming rod will result in:
Eccentric reaming of the far cortex
Damage to the reamer head connection, resulting in metal
fragments in the canal.
NOTE:
For an antegrade femoral approach, if possible,
adduct the limb/hip to facilitate access to entry
point. For greater trochanter entry point,
target >2cm distal to the lesser trochanter.
1
For an antegrade tibial approach, the knee will
need to be flexed to 90-110° for entry site access.
Insert the guide wire aiming down the tibial crest,
and thus the center of the medullary canal.

REAMING
1. INTRODUCE RIA 2 SYSTEM INTO
MEDULLARY CANAL
Ensure the clamps on Irrigation and Aspiration Tubes are open.
Guide the Reamer Head over the 2.5 mm reaming rod and into the prepared
canal opening of the bone.
NOTE:
Prior to insertion into patient’s limb, ensure irrigate is flowing and
suction is present at the aspiration holes at the tip of the assembly.
Advance the RIA 2 System, without power, over the reaming rod until the
Reamer Head is inserted into the entry point of the canal.
Check position on the image intensifier.
NOTE:
Flow of aspiration begins when aspiration holes are fully immersed
in the bone.
CAUTION:
Never ream when there is no irrigation/aspiration. The irrigation/
aspiration fluid cools the Reamer Head and removes bone marrow
and morselized bone from the medullary canal. Fluid flow is
crucial for proper system performance.
RIA 2 (Reamer Irrigator Aspirator) Surgical Technique DePuy Synthes 11
3. TURN OFF IRRIGATION
AND ASPIRATION
When reaming is completed, retract the RIA 2 System
and turn off the irrigation and suction.
2. REAM
Minimize direct soft tissue contact with suction holes to prevent potential
clogging.
Using the power driver in drill setting, begin reaming under power, slowly
advancing the Reamer Head 20–30 mm and then retracting 50–80 mm,
allowing the irrigation fluid to flow in front of the Reamer Head. Advance the
RIA 2 System until resistance is felt, then repeat the advance and retraction
technique to continue reaming.
Use intermittent image intensification to monitor the Reamer Head position
during reaming.
NOTE:
An insufficient irrigation volume may lead to clogging. To prevent
clogging, avoid rapid advancement of the assembly.
CAUTION:
Periodically check that the reaming aspirate is flowing through the
tube and into the suction canister. If there is no material flow, stop
reaming, turn off suction and retract the reamer head outside the
patient to evaluate for obstructions in the flow path.
Stop suction if the reaming is paused with reamer in the canal.
Extended reaming under suction may result in excessive blood loss.
Clamps on the suction tube can also be used to stop suction.
After the Reamer Head reaches the desired depth, withdraw the RIA 2 System
with power on until the Reamer Head is at the canal entry site.
