In our case, we followed the preoperative protocols proposed by many authors including preoperative workup to exclude infection, (CBC, ESR, CRP), CT angiography to detect displacement of the vessels and to exclude the presence of aneurysm, and CT to accurately delineate the amount of pelvic osteolysis and to exclude the presence of pelvic discontinuity [1,4]. The gene discussed is CRP; the disease is infection.
