Event or Problem Description
During primary left anatomic shoulder replacement, surgeon was preparing the glenoid surface to receive a perform + left small 15deg poly implant.Procedure had proceeded without incident, until the step to utilize the keeled osteotome and punch, which attaches on to the handle in instruments.The handle was found to be broken.The locking sleeve was completely separate to the main handle shaft.Attempts to reattach the sleeve onto the handle so the osteotome / punch can be locked to the handle, proved fruitless.In the end, the surgeon first placed the osteotome (over the guide wire still insitu) into the semi-prepared "keel hole", then placed the handle on to the end of the osteotome, and impacted the osteotome.With the handle not attached to the osteotome, the only way to remove the osteotome, was grabbing it with a pair of heavy pliers, and hitting the pliers with a mallet to back it out.This process was repeated for the punch.The surgeon was happy that the keel-hole was adequately prepared (the trial implant seated home fully when inserted into the glenoid), but the surgeon was concerned about possible damage to the glenoid surface / vault, when using the mallet / pliers to remove the osteotome / punch.
