Abstract

Purpose: Fracture-related infections (FRI) pose a difficult management problem, as they require numerous surgical interventions and extended antibiotic treatments, especially when a multidrug-resistant organism is involved, with a paucity of available literature that provides guidance.

Results: A 42 year-old male presents an open diaphyseal tibia and fibula fracture, complicated by soft tissue necrosis and infections caused by extensively drug-resistant Acinetobacter baumannii (XDR-Ab). Initially treated with a damage control external fixator, the patient underwent multiple surgical procedures, including radical debridement, negative pressure wound therapy, external fixator revisions and reconstructive surgery using a latissimus dorsi free flap. The emergence of colistin resistance in the Acinetobacter baumannii strain led to the compassionate use of cefiderocol, finally achieving clinical cure.

Conclusions: This case report is one of the firsts that highlights the potential efficacy of cefiderocol in treating challenging bone and joint infections sustained by XDR-Ab. The successful outcome also emphasizes the importance of a comprehensive, multidisciplinary approach in achieving favorable results in complex FRI.
