Event Description
|
The patient's legal counsel reported that the patient was implanted with an aura ii stem, a crco head and a magnum acetabulum on (b)(6) 2010.Following this total hip arthroplasty, the patient suffered from pain, however, he got back to professional life.On (b)(6) 2017, the patient fell and the prosthesis has decompensated.It was therefore seen through x-ray that the patient suffered from bipolar geodic reaction following a release of ions by the prothesis.Indeed, it was reported that the metal friction between the prothesis components has led to inflammatory granulomas with a phenomen of bone resorption.On (b)(6) 2020, the patient underwent a revision surgery to remove the prothesis.The delay observed between the fall on (b)(6) 2017 and the revision surgery can be explained by the implantation of a total hip prothesis on the left hip.This report is based on allegations set forth in patients notice and the allegations there in are unverified.

It was reported that patient underwent initial right total hip arthroplasty subsequently, the patient was revised approximately 10 (ten) year later due to pain, difficulties, and instability.The patient was reported to have loosening and osteolysis of the acetabular cup as well as osteolysis of the proximal femur with significant bone loss requiring bone grafting and osteosynthesis stabilization during the revision.Attempts have been made and no further information has been provided.

(b)(4).This follow-up report is being submitted to relay additional information.The following sections were updated: b4, b5, g3, g6, h1, h2, h6, h10.No product was returned or pictures provided; visual and dimensional evaluations could not be performed.Review of manufacturing records cannot be performed without product identification.Medical records were provided and reviewed by a health care professional.Findings: patient had consultation for shoulder and lumbar spine complaints, follow up for neuro assessment post ischemic stroke, chronic low back pain, shoulder pain, weakness and flexion limitation noted in the left (contralateral) hip due to arthritis, no right hip complaints at this time.Patient pursued rehab for post-fall pain in the lower right extremity, pain in the right thigh with feeling of instability, required rehab for several months.Patient had a fall a few years ago (no resulting complications), no limb length inequality, pain in the trochanter, x-rays ordered to assess for possible periprosthetic lesion.Patient reports painful episodes in the right hip, especially when getting in/out of the car, stopped working due to pain.Infection ruled out with aspiration, x-rays show osteolysis, acetabular revision recommended.Left hip surgery also planned due to arthritis.Ct shows right hip osteolysis at the proximal femur with acetabular loosening and osteolysis.X-rays showed a cup tilt of 59°, presence of significant femoral osteolysis led to plans to change out the femoral stem as well.Significant bone loss leading to fracture at the greater trochanter during revision, unknown if during initial implant removal or implantation of competitor product but appears to have been corrected with synthes osteosynthesis stabilization.Appears that the greater trochanter fracture identified in the revision surgery was repaired with synthes plate and cerclage wires, surgery performed to correct a broken pin, no complaint required as this is competitor product.With the available information, a definitive root cause cannot be determined.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.
