Manufacturer Narrative

Reported event: an event regarding loosening involving an omnifit stem was reported.The event was not confirmed.Method & results: -device evaluation and results: material analysis, visual, functional and dimensional inspections could not be performed as the device remains implanted.-clinician review: a review of the provided medical records by a clinical consultant indicated: this inquiry concerns a patient who sustained a fracture of the right femoral neck after falling.Surgery was performed with a cementless femoral component and a bipolar hip articulation.The patient continued to complain of pain not so much in the groin but rather in the right thigh.The patient had concomitant spine issues and diagnostic spinal injections alleviated 100% of the patient's pain.The patient however continued to complain of pain and was seen by another orthopedic surgeon who diagnosed a "possible loose femoral prosthesis." no supporting documentation for that diagnosis was given except some ¿stress lines more distal than proximal¿.The surgeon recommended revision surgery.I can confirm that the patient sustained a femoral neck fracture which was treated with a cementless bipolar arthroplasty since i was able to see the preoperative and postoperative x rays.I have no further x-rays to evaluate so i cannot confirm any possible changes in the position or configuration of the implant, especially the ¿stress lines more distal than proximal¿.A consulting orthopedic surgeon diagnosed a "possible loose femoral component" with no supporting documentation and no x-ray findings suggestive of loosening except some ¿stress lines more distal than proximal¿.No workup for infection or any other cause was presented.I cannot determine the root cause of this event with certainty.This patient had spinal injections which relieved her symptoms 100%.The patient never had an intra-articular injection with an anesthetic which would help to corroborate pain from the acetabular portion of the implant.As i mentioned above, i have no further x-rays to examine that might implicate any problems with the implant itself.The causes of pain following cementless bipolar arthroplasty are multifactorial.These include loosening, infection, pain from an un-resurfaced acetabulum and pain from remote sources such as the spine and stress fracture.Also, causes include surgical technique, patient factors including activity level and bmi, and implant factors.-device 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.Conclusion: it is also noted that the patient inquired if their devices are subject to a recall.Based on the catalog and lot information provided the product is not subject to a product recall.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.
