Case: A giant seroma developed in the hip of a 44-year-old man after resection arthroplasty performed for recurrent periprosthetic joint infection (PJI). The seroma persisted despite joint reconstruction but was ultimately treated successfully by internal drainage through a coxoperitoneal shunt.
Conclusion: Resection arthroplasty of the hip is considered a salvage procedure for failed implant retention in the situation of persistent PJI. Nevertheless, functional results are poor and further soft-tissue complications may occur. A giant seroma of the hip may be drained into the peritoneal cavity, permitting healing without risking contamination from external, percutaneous drainage.
