Surgical Treatment of Intrapelvic Pseudotumour after Hip Resurfacing Arthroplasty: Case Report and Literature Review

Abstract EN

Hip replacement is the surgery of the last century due to its impact on the quality of life.

A pseudotumour is a rare complication of hip arthroplasty, and it is related to a metal-bearing surface.

Pseudotumour is a challenging scenario for hip surgeons due to poor clinical outcomes.

The patient consulted for hip pain and paresthesia in the left lower extremity, and analyses showed that the cause was a sizeable intrapelvic pseudotumour.

A multidisciplinary team surgery was planned.

At first, an infraumbilical approach was made to resect the intrapelvic-retroperitoneum portion of the pseudotumour.

Then, a posterolateral hip approach was performed, to resect the remaining portion of the pseudotumour and revision arthroplasty.

At five years of follow-up, there are no clinical or imaging signs of recurrence of the pseudotumour.

Treatment evidence is limited to a series of cases and expert opinions; we encourage complete resection and revision arthroplasty.
