Intrafat Sequestration of Artemisinin Disguised as a Purulent Collection during a Posterolateral Hip Approach

Abstract EN

The posterolateral hip approach is the oldest and most used way to implant total hip arthroplasty.

The anterior part of the oblique portion of this posterolateral approach corresponds more or less to the superolateral quadrant of the buttock in which the intramuscular injection of various drugs, including the compounds derived from artemisinin, is carried out.

Thus, in a malarial endemic area where gluteal injections of the compounds derived from artemisinin are not rare, poor performance of an injection by the deposition of the product in the fat and not deeply in the muscle can be at the origin of the sequestration of the drug in adipose tissue and give the macroscopic appearance of a pus.

The authors present a case of intrafat sequestration of artemisinin taken for purulent collection during a posterolateral hip approach for total hip arthroplasty.
