• Periprosthetic acetabular fractures are uncommon and infrequently the focus of studies.
    • Acetabular fractures are occasionally recognized postoperatively when patients report unremitting groin pain weeks after surgery.
    • The widespread use of cementless acetabular cups might lead to a higher number of fractures than are clinically detectable.
    • Appropriate recognition, including mindfulness of preoperative patient and surgical risk factors, is critical to the successful management of acetabular complications.
