Recurrent femoral deep vein thrombosis: rare complication of a pelvic mass induced by polyethylene wear debris following total hip arthroplasty. A case report.

Pelvic osteolysis is a well-known complication following total hip arthroplasty (THA) [1], both with and without cement [2], [3] and [4]. It has been attributed as the biological response to wear debris of several materials, but polyethylene particles are the most implicated agents [5], [6] and [7]. The occurrence of a pelvic mass induced by a foreign-body reaction (granuloma) has been rarely described as a complication of particulate polyethylene debris (PED) [8], [9] and [10]. A never before-seen vascular complication, recurrent femoral deep vein thrombosis (DVT), produced by the compressive mass is reported here
