It was reported via a clinical study that a patient underwent a bone fixation procedure of the right femur.On an unknown time frame post-implantation, the patient developed a traumatic right femoral hematoma with a wound healing disorder.Blood cultures tested positive for e.Coli in sepsis and a smear also tested positive for e.Coli.Subsequently, the patient underwent medical intervention including a jet lavage procedure to clear the hematoma and wound.Due diligence is complete as multiple attempts have been made; however no further information is available and the product remains implanted.

This follow-up report is being submitted to relay additional information.D10: medical product: retrograde femoral nail - purple 10 mm diameter 36 cm length: catalog#: 47249436010, lot#: 61295569; 6.0 mm diameter cancellous screw - black fixed angle 3.5 mm hex head: catalog#: 47248405060, lot#: 61143263; 6.0 mm diameter cancellous screw - black fixed angle 3.5 mm hex head: catalog#: 47248406560, lot#: 61374592; 6.0 mm diameter cancellous screw - black fixed angle 3.5 mm hex head: catalog#: 47248405060, lot#: 61236378; 5.0 mm diameter cortical screw - red fixed angle 3.5 mm hex head: catalog#: 47248403250, lot#: 61812273; 5.0 mm diameter cortical screw - red fixed angle 3.5 mm hex head: catalog#: 47248403750, lot#: 61711476.The reported infection/sepsis that developed was identified as positive for e.Coli bacteria, which was obtained via culture of the hematoma.A hematoma is a mass of clotted blood that forms in a tissue, organ, or body space.A hematoma can be associated with pain, swelling, ecchymosis, serosanguinous or bloody drainage after a recent surgical procedure or trauma and can predispose the patient to infection.The development of a postoperative hematoma can be correlated with the surgical procedure and perioperative anticoagulation therapy prescribed to prevent thrombus formation.Most hematomas resolve on their own, without surgical intervention, while some do not.Larger hematomas may need to be surgically evacuated in order to resolve.As timeframes of onset differ due to individual contributing factors, a specific timeframe of expected occurrence cannot be established.Investigation results concluded that the reported event was due to non-device related factors.Device history record was reviewed and no discrepancies related to the reported event were found.Sterile certifications were also reviewed and found to be conforming with no applicable deviations.Devices were verified to have gone through acceptable sterilization process following iso/aami/astm & eu published guidelines.There are multiple factors that may contribute to an infection that are outside the control of zimmer biomet, such as external factors, i.E.Hospital/surgical environment, provider related risk factors, and/or patient comorbidities/risk factors.As there are no indications of a product or process issues identified affecting implant safety or effectiveness, implanted products are not identified as the source or contributing to the reported infection.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
