Extract
Following total hip arthroplasty, accelerated polyethylene wear is often
associated with periprosthetic osteolysis, which may be asymptomatic or may
present with groin
pain1,2.
Rarely, the patient may have a periarticular mass and may present with
compression symptoms that can include neuropathy, venous thrombosis, and even
urinary
obstruction3-10.
We report the cases of two patients who presented with unilateral swelling of
the lower extremity secondary to compression of the iliac vessels by an
intrapelvic mass associated with acetabular polyethylene wear. Both patients
were treated surgically, and both had a successful result on the basis of
clinical and radiographic findings. Both patients were informed that
information regarding their case would be submitted for publication.
