Protrusio Acetabuli Prosthetica - a cause of a Pelvic Mass Presenting to the Gynaecologist.

INTRODUCTION

Intrapelvic complications resulting from total hip arthroplasty are rare. Intrapelvic migration of the acetabular cup along with proximal migration of the femoral stem is one of these entities. Despite being a rare entity, there are serious complications.

CASE REPORT: We report a case image of an elderly lady who presented 6 months after total hip arthroplasty to her general practitioner and gynaecologist complaining of a palpable hard pelvic mass as well as difficulty walking. This proved to be the result of protrusio acetabuli prosthetica. This was reconstructed using saddle prosthesis.

CONCLUSION

Protrusio Acetabuli Prosthetica can present as pelvic mass without any other associated symtoms. Although a rare complication, with noted morbidity, it might still be reconstructable.
