Manufacturer Narrative

Reported event: an event regarding limb length discrepancy involving a patient specific, distal femur, femoral stem was reported.The event was not confirmed.Device evaluation and results: not performed as product was not returned clinician review : a review of the provided x-rays by a clinical consultant indicated: the implant in situ was for a distal femoral replacement which was inserted on (b)(6) 2017.Surgeon reported that the patient had implant infection but cleared after treatment, instability of the femoral implant and leg length discrepancy.Ct scan provided showed massive radiolucent lines around the femoral stem, with severe bone defects and osteolysis that could be caused by previous infection.On the lateral view of the image, the bone has fractured at the tip of the stem.All these defects observed can lead to loosening and instability of the stem.Because the ct scan only showed the affected leg, the leg length discrepancy cannot be assessed.Therefore, the radiographic assessment can confirm the reason for revision.Device history review: review of the product history records indicate 1 devices was manufactured and accepted into final stock on 11 jan 2017 with no reported discrepancies.Complaint history review: there have been no other events.Conclusion: the exact cause of the event could not be determined because insufficient information was provided.Additional information including operative reports, pathology reports, progress notes, x ray images, and return of the device are needed to fully investigate the event.If further information becomes available or the product is returned, this investigation will be re-opened.
