Intraoperative periprosthetic fractures are challenging complications that may affect implant stability and survivorship. Periprosthetic acetabular fractures are uncommon and infrequently are the focus of studies. Acetabular fractures are occasionally recognized after patients report unremitting groin pain weeks postoperatively. The widespread use of cementless acetabular cups might lead to higher number of fractures than is clinically detectable. Conversely, the incidence of intraoperative periprosthetic femoral fractures are more common and encompass a broad spectrum, ranging from a small cortical perforation to displaced fractures with an unstable prosthesis. Appropriate recognition, including mindfulness of preoperative patient and surgical risk factors, is critical to the successful management of acetabular and femoral complications. This comprehensive review article focuses on the incidence, patient and surgical risk factors, diagnosis, management, and clinical outcomes associated with intraoperative acetabular and femur fractures in primary total hip arthroplasty.
