We report a 59-year-old male with left leg osteomyelitis caused by an XDR Pseudomonas aeruginosa strain following a road traffic accident. Limited treatment options and adverse antimicrobial reaction led to consideration of cefiderocol together with appropriate surgical intervention. Improved bony remodelling over the tibia and fibula was observed with good bony alignment and no adverse features. Physiotherapy support was continued for 4 months following treatment, which resulted in good functional mobility, improved proprioception and full ability to bear weight. This case also adds to multiple reports that describe safe and successful use of cefiderocol to treat MDR, aerobic Gram-negative infections.
