Event Description
|
The customer reported that problems were encountered with the final turn of the lag screw inserter.The bone was hard and the surgeons had tapped to account for this.When measuring for the lag screw they had taken 5 off the measurement and therefore over reamed.When trying to turn the lag screw handle parallel to allow the plate to pass over the lag screw and sit onto the near cortex, the lag screw implant sheared off the insertion device and became bent/twisted.This meant it was then impossible to remove the lag screw and it had to be manipulated to allow the plate to pass over the top of it and into place.The operation was completed and it added around 1 hour to the operating time.No pieces fell into the wound.The lag screw was already inserted when the issue was discovered.The decision was made that it would be clinically safer to leave the screw in situ rather than remove it.The customer reported that the lag screw inserter is functional.The patient¿s bone quality was good, hence the reason the surgeon tapped the bone before he inserted the lag screw.The patient had a general anaesthetic and a regional block so no additional analgesia was needed.However the patient was anaesthetised for longer than would normally be necessary for this type of procedure.
