Sterile abscess with subsequent iatrogenic draining sinus tract formation 3 years after fiberwire and ENDOBUTTON distal biceps brachii tendon repair: A case report

Case: We report a case of a sterile abscess with subsequent sinus tract formation mimicking infection 3 years after uncomplicated distal biceps brachii tendon repair with FiberWire suture in a 42-year-old man. The preoperative workup for infection was unremarkable. Intraoperative culture specimens confirmed the absence of infection. Excision of the sinus tract and FiberWire-ENDOBUTTON construct was curative. At the 1-year follow-up, there had been no recurrence of symptoms. Conclusion: Foreign-body inflammatory reactions should be considered in the differential diagnosis of patients with apparent infection with a history of FiberWire suture fixation and negative serologic workup.
