Device history records were reviewed with no deviations or anomalies identified that would have contributed to the reported event.The product was not returned; therefore, the exact condition of the cables is unknown.This device is used for treatment.Patient records were returned for review.Mri right hip notes dated (b)(6) 2016 indicates that there is metal-on-metal right hip total arthroplasty, but there is no periprosthetic fracture at this time.Operative notes dated (b)(6) 2016 indicate that the patient underwent a revision for a failed right total hip arthroplasty due to acetabular component loosening.Pre and post-operative diagnosis does not indicate any kind of fracture.Lack of cupping growth and corrosive debris with large fluid collection and elevated titanium levels were noted in the patient history.All original hip components were explanted, even the well-fixed stem, due to the elevated titanium ion levels noted pre-operatively.Following, new hip components were implanted and achieved equal leg lengths and stability.The hip was then passively abducted 5 degrees in neutral rotation and the osteotomy was contoured internally at its proximal portion, and then closed with two cerclage cables.Small amount of acetabular host bone grafts were obtained from the acetabular reamers and then pressed about the edges of the osteotomy to promote healing.The exact reason for the osteotomy was not indicated within the operative notes.Operative notes dated (b)(6) 2016 indicates that a displaced greater trochanteric fracture was identified.The previously placed zimmer ready cables were cut and removed at this time and the hip was observed to be dislocated posteriorly.Operative notes indicate the fracture was reduced and new cables were assembled.Once fragment rigidity was achieved, the cables were crimped, tensioners were removed, and cables were cut.Excellent stability was noted.The hip underwent full range of motion and all fragments appeared stable.A definitive root cause of the periprosthetic fracture cannot be determined with the information provided.
