Septic Arthritis of the Hip and Enterocutaneous Fistula Formation After Hip Arthroscopy: A Case Report of Psoas Abscess Misdiagnosed as Labral Pathology.

Methods: We describe a case of septic hip arthritis and enterocutaneous fistula formation caused by the seeding of a hip joint during hip arthroscopy performed in the setting of a psoas abscess. Treatment consisted of multiple debridements and femoral head resection with subsequent total hip arthroplasty.

Conclusions: This case highlights the importance of a thorough history, physical examination, and assessment of available imaging before proceeding to surgery, even when the procedure is one considered to have minimal risks, such as arthroscopy.
