Retention of a Well-Fixed Acetabular Component in the Setting of Massive Acetabular Osteolysis and Pelvic Discontinuity

he management of massive pelvic osteolysis can pose a substantial challenge when a revision total hip arthro-plasty is performed. For patients with well-fixed, well-positioned acetabular components and with contained osteolytic defects, retention of the prosthesis with bone-grafting of the osteolytic lesions is an accepted surgical strategy1-4. In contrast, in the setting of massive osteolysis with pelvic discontinuity, the acetabular component is usually loose and must be revised. To our knowledge, the uncommon clinical scenario in which pelvic discontinuity and massive osteolysis are associated with a well-fixed acetabular component has not been discussed in the literature. In the following case report, we describe the surgical treatment and clinical results of a patient with this challenging combination of problems. The patient was man-aged with acetabular component retention, open reduction an
