Event Description

It was reported that the patient had a fracture reverse shoulder about 3 years ago.Unfortunately, the primary had failed as the patient suffered a peri-prosthetic fracture below the distal tip of the in-situ stem, while using their arm to push off of a chair.During the revision the existing stem was removed (which took a large chunk of proximal humeral bone with it).The surgeon then reamed down the humeral canal to replace the stem with an srs humeral component.During reaming he found that the reamer skived off an existing cement restrictor form the primary procedure and perforated the humeral canal.He then had to drill in to the cement restrictor to be able to remove it before proceeding with humeral reaming.The surgeon was able to successfully complete the humeral preparation before trialing the new humeral component on the existing in situ glenosphere.The surgeon began with the smallest srs proximal body before building up to the 68mm body.He also trialed a number of humeral tray and poly constructs (from smallest to largest) before settling on the +5mm thickness tray and +3mm thickness poly.This was then implanted before closing up.
