Additional Manufacturer Narrative
A polarstem collar reamer guide (75102205), used in treatment, was not received for evaluation.It was reported that when cleaning and putting the polarstem collar reamer guide set together, the spring came out of the reamer guide.This did not happen during a procedure, there is no information available on how the reamer guide broke.A visual analysis could not be conducted, as the part was not returned.The production documentation was not reviewed, as not batch number was received.The review of the complaint database showed that similar cases were reported in the past, one of which led to a corrective and preventive action.A design review was performed which demonstrated that the hook may contact the reamer if it is not fully engaged to the rasp during reaming.This collision might lead to a fracture of the hook and the spring can become loose.However a breakage was not reported in this case.A new design of the device has been released in order to prevent the reoccurrence of this issue.The failure mode cannot be independently confirmed as the part was not returned.The root cause is attributed to insufficient design specifications.Further investigations have been initiated to review the performance of this device.This complaint has been reopened for reporting reasons, according to the current procedure.No additional information became available.Should the device be returned, this complaint will be reassessed.Smith and nephew will monitor this version of the device for further similar issues.
