To prep the humeral canal for the Arthrex Shoulder Fracture System how do you ream?

• A. Ream to size
• B. Ream, then broach
• C. Ream, then broach a size under
• D. Ream then broach a size over

Answer: (A)

Achieving the exact canal diameter for a secure, stable stem seating is the key idea. Reaming to size means you remove bone until the canal matches the diameter of the chosen humeral stem, giving a precise, snug fit and proper alignment without extra steps. This approach preserves bone and avoids over- or under-preparation that can happen if you add a broach step or oversize/undersize with a broach. In this system, the final implant seating is determined by the ream-to-size match, so reaming to the actual implant size best prepares the canal for reliable fixation.
