Clostridial myonecrosis is a diffuse necrotizing infection of deep soft tissues. It is known for its acute, rapid progression, poor prognosis, and high mortality. We report a case of traumatic clostridial myonecrosis, a 17-year-old, previously healthy female reported to our department with the complaint of pain in her left arm a week after she suffered a fall from her chair on to her left arm. Due to the injury sustained in the incident, under suspicion of a forearm fracture, a cast was applied to her left arm at a local polyclinic. However, after a few days, she reported unbearable pain, which led to the removal of the cast, and that is when diffuse crepitations due to gaseous accumulation were noted in her entire left upper limb. A week later, X-ray studies failed to reveal any fracture or abnormality. The patient was started on broadspectrum antibiotic coverage with intravenous (IV) benzylpenicillin, rifampicin, and clindamycin for a considerable period of time, but there was no improvement in her condition and the infection continued to spread into adjacent soft tissues, requiring intervention with hyperbaric oxygen therapy.
