Enteroarticular Fistula Following Antibiotic Spacer Placement for a Periprosthetic Joint Infection in a Patient with Chronic Pelvic Discontinuity: A Case Report.

CASE: A 50-year-old man with a history of chronic refractory periprosthetic joint infection following total hip arthroplasty, which had been treated with multiple antibiotic spacers, developed an enteroarticular fistula. He was able to avoid hip disarticulation after undergoing a laparoscopic colectomy with a diverting colostomy and a functional hip resection arthroplasty. At the 1-year follow-up, he was walking independently with crutches and had minimal pain.

CONCLUSION: An enteroarticular fistula following total hip arthroplasty is a rare and serious complication. To our knowledge, this is the first reported case that occurred in the setting of an antibiotic spacer. A multidisciplinary team approach is essential for achieving clinical success.
