It was reported that a curved radial head stem did not fit correctly into place during a left radial head prosthesis revision procedure.The purpose of the revision was to replace a short stem with a long stem as the patient had reported post-operative pain following the original procedure (which utilized a competitor's device).X-rays prior to the revision procedure indicated that the implanted device had "wollered out" or migrated.During the revision procedure, an 8mm curved radial stem was inserted after reaming.The surgeon indicated that the stem did not fit correctly.The head of the stem did not articulate with the capitulum and appeared to be pointing out backwards toward the olecranon.The implant was removed and reassembled on the back table.Upon reinsertion, the surgeon turned it 180 degrees; the device fit perfectly.A ninety (90) minute delay was noted.The procedure was completed without further incident.This report is 2 of 2 for com-(b)(4).
