Event Description

It was reported that the patient underwent revision surgery due to aspectic loosening at cement mantle and joint impingement, caused by fall trauma.Revision took place approximately two (2) years three (3) months from initial total hip arthroplasty.Attempts have been made and no further information has been provided.

Manufacturer Narrative

(b)(4).This follow-up report is being submitted to relay additional information.No product was returned or pictures provided; visual and dimensional evaluations could not be performed.A review of the device manufacturing records confirmed no abnormalities or deviations.Device is used for treatment.Medical records were provided and reviewed by a health care professional.The patient is female, born in 1949, 160cm and 62kg (bmi 36).The patient underwent an initial right tha on (b)(6) 2022 because of osteoarthritis.On (b)(6) 2023 the patient sought medical advice due to right hip pain after a fall/slip injury.Medical notes of the consultation reports that the initial surgery was complicated by a fracture of the greater trochanter which turned into chronic bone nonunion.During consultation, doctor reviewed a bone scan performed on (b)(6) 2022 and ordered new radiography.Bone scan review suggested periprosthetic activity adjacent to the right hip prosthesis due to a possible loosening or infection.X-ray examination confirmed the fragmentation/non union of the greater right trochanter and revealed subsidence of the stem in the cement mantle.Subsequently, patient underwent revision surgery on (b)(6) 2023.Radiographs were received and reviewed by a radiologist.All of the provided images demonstrate a periprosthetic lucency which surrounds the entirety of the cemented femoral component with greater lucency at the lateral and proximal intertrochanteric region which appears to be consistent with the reported history of aseptic loosening.Hardware is otherwise intact and normally aligned.Chronically fragmented nonunited fracture of the greater trochanter.Remaining bones intact and normally mineralized.No dislocation.The head was removed together with the loose stem, but no issue was identified for the head itself.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.
