INTRODUCTION AND IMPORTANCE: Several studies have discussed trunnionosis in metal-on-metal total hip arthroplasties. However, trunnionosis in metal-on-polyethylene total hip arthroplasties has been less frequently discussed.
CASE PRESENTATION: In this study, trunnionosis in two male patients undergoing metal-on-polyethylene total hip arthroplasty, which was done to treat femoral head osteonecrosis were reported and discussed adequately.
CLINICAL DISCUSSION: Total hip arthroplasties (THA) were done for the treatment of femoral head osteonecrosis in these cases. In the first case, trunnionosis occurred one year after the revision of the primary THA, and in the second case occurred ten years after the primary THA. Both of these cases were presented with reduced range of motion. After surgery, the symptoms were resolved, and the patients remained complication-free until the last follow-up.
CONCLUSION: This report raises awareness regarding the importance of trunnionosis as a serious complication of modular total hip arthroplasty.
