It was reported that due to a mistake, supposedly caused by the hospital`s sterilization department, the subject received a 4 -hole dhs side plate made by synthes which was combined with a lag screw made by stryker.Since those two components are not compatible, the implant failed which required an additional surgical intervention (i.E.Revision surgery) seven days after the initial surgery during which the subject received a new stryker omega3 s-hole dhs including a compatible stryker lag screw.

Investigation evaluation: the reported event that the stryker screw was used with a non stryker plate could not be confirmed, since the device was not returned for evaluation.Based on the investigation, the root cause of the reported event was attributed to a user related issue.It was reported that the healthcare facility mistakenly used a stryker screw with a non stryker plate which was not compatible.The instructions for use states: ¿do not use components of the stryker osteosynthesis product systems in conjunction with components from any other manufacturers¿ system unless otherwise specified.The operative technique for the omega 3 system compression hip screw lists no components from other manufacturers as being compatible with the omega 3 system.A review of the device history was not performed because the lot number and catalog number were not communicated, and because the reported event did not allege a product failure or manufacturing defect.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.If any further information is provided, the investigation report will be updated.
