This report is being resubmitted for an incident that occurred earlier.The instrument was returned for evaluation and was observed to be missing one of the two prongs that engage with the implant assembly.Investigation found the surgeon used a kocher knob to turn the knurled knob counterclockwise in an effort to disengage the narrow implant holder from lhe implant.The use of a kocher may have applied unnecessary torsion on the prong leading to it breaking.It is unclear as to the exact cause of the holder becoming stuck to the implant assembly.The following sections have been updated for this supplemental report: b4, e1, h2, h6, h10.
