In the setting of paediatric osteomyelitis do not be afraid to CAST an eye

The case commences with an innocuous right ankle injury (lateral malleolus), for which the patient, a 9-year-old boy, was placed in a temporary cast at his local hospital. Three days following this incident, the patient was diagnosed with new-onset type 1 diabetes mellitus. He was admitted to his local hospital with severe diabetic ketoacidosis appropriately treated and subsequently discharged c.1 week later clinically well. Approximately 1 week later, again he presented for a third time with a significant serosanguinous discharge from the site of the initial injury permeating through the temporary cast in place for c.2 weeks by that time. On removal of the cast, a severely invasive infection of bone and soft tissue was noted, and the patient was urgently transferred to our unit at the tertiary general hospital for further management. He underwent a series of orthopaedic and plastic surgery procedures with an eventual satisfactory outcome.
