Reported event: an event regarding crack/fracture involving an exeter stem was reported.The event was confirmed.Method & results: product evaluation and results: the reported device was in-vivo for a period of 10 years.¿the implants are designed to function as intended for at least ten years post-implantation under normal use conditions¿.Given the duration of implantation, interaction of various factors and longevity of the implant dependent on patient weight and level of activity, the device shall not require a material analysis as it has exceeded the expected life of the device." clinician review: a review of medical records with a clinical consultant indicated "i can confirm that the patient underwent a primary cemented exeter total hip arthroplasty on the left side if conventional orientation was utilized.I can confirm that a fracture of the femoral stem was present.I can do so since i was able to view radiographs with the implant and the fracture in place.While the event description mentions that revision surgery was carried out, i cannot confirm that because i have no supportive documentation other than that notation.Root cause analysis: the root cause of this event cannot be determined with certainty.The root causes of late femoral, stem fracture of an exeter femoral implant are multifactorial.These include surgical technique, especially in the way that the cement is inserted, and the implant secured.In this case, the cement mantel was grade c/d.If the implant was relatively fixed distally, the proximal portion of the implant could toggle and a stress fracture can occur.Other factors, including patient¿s lifestyle, activity level, and bmi can contribute as well as implant factors." product history review: review of the device history records indicate devices were manufactured and accepted into final stock with no relevant reported discrepancies.Complaint history review: there have been no other similar events for the lot referenced.Conclusions: it was reported that the patient was revised due to fracture of the stem.The reported device was in-vivo for a period of 10 years.¿the implants are designed to function as intended for at least ten years post-implantation under normal use conditions¿.Given the duration of implantation, interaction of various factors and longevity of the implant dependent on patient weight and level of activity, the device shall not require a material analysis as it has exceeded the expected life of the device." a review of medical records with a clinical consultant indicated "i can confirm that the patient underwent a primary cemented exeter total hip arthroplasty on the left side if conventional orientation was utilized.I can confirm that a fracture of the femoral stem was present.I can do so since i was able to view radiographs with the implant and the fracture in place.While the event description mentions that revision surgery was carried out, i cannot confirm that because i have no supportive documentation other than that notation.Root cause analysis: the root cause of this event cannot be determined with certainty.The root causes of late femoral, stem fracture of an exeter femoral implant are multifactorial.These include surgical technique, especially in the way that the cement is inserted, and the implant secured.In this case, the cement mantel was grade c/d.If the implant was relatively fixed distally, the proximal portion of the implant could toggle and a stress fracture can occur.Other factors, including patient¿s lifestyle, activity level, and bmi can contribute as well as implant factors." no further investigation for this event is possible at this time.If additional information become available to indicate further evaluation is warranted, this record will be reopened.
