Manufacturer Narrative

H3, h6: it was reported that, during a thr surgery, while impacting the handle of a plus sl-plus mia dbl offset adapt.Lt 60/25mm broke, all parts were retrieved by hand.The device, used in treatment, was returned for investigation.Upon visual inspection, the fracture at the connection between the contact pin and the body of the adapter could be confirmed.A review of the production documentation did not reveal any deviation from the standard operating procedure.A review of the batch record revealed two additional complaints for the batch in question.However, both complaints were reported for a different issue not related to device fracture.A review of the risk management documentation verifies the failure mode and severity of the reported issue.Review of past corrective actions was performed.No further escalation is required.A medical investigation was conducted.Since no patient injuries are being reported no further clinical/medical assessment is warranted at this time.According to document "processing (cleaning, disinfection and sterilization) of instruments from smith & nephew orthopaedics ag" (lit.N°03389-en 1363 v3 11/19), all instruments must be inspected and controlled for proper functioning after cleaning/disinfection.Instruments should only be used in their original condition (lit.No.12.23 ed.05/16).Based on the performed investigations, the reported fracture could be confirmed.The relationship between the reported event and the device was confirmed.There is no indication that the reported device failed to meet manufacturing specifications upon release for distribution.This instrument is designed to hold and guide the detachable rasps for broaching.It is therefore subjected to repeated impact forces via the modular knock plate or the pneumatic woodpecker.Previous investigations demonstrated, that under specific circumstances, this device may fracture during impaction.The root cause is therefore attributed to inadequate design.An optimized design of the device has been released in order to reduce the occurrence of this issue.This version of the device will be monitored for similar issues.The returned device will be discarded.
