Late Disassembly of Femoral Head and Neck of A Modular Primary Total Hip Arthroplasty.

INTRODUCTION

Modular total hip arthroplasty system are now widely used, as these components increase the flexibility during primary and revision total hip arthoplasty. But this modularity itself associated with some risk of intraoperative and postoperative complications.

CASE REPORT

We report a case of late disassembly of a primary total arthroplasty in a 42 years old patient five years after the replacement surgery where the femoral head remained in the acetabular socket.

CONCLUSION

Femoral head should be solidly impacted onto the stem and confirm that it has been assembled correctly before reduction.
