Dear Editor,

Osteomyelitis is an infection of the bone; this commonly involves the long bones such as that of the extremities; organisms commonly implicated are Staphylococcus aureus, Haemophilus influenzae type b, and Streptococcus pneumoniae, and in sickle-cell anemic patients, salmonella typhi have been implicated.[1] The bacterial profile of osteomyelitis in sickle-cell disease (SCD) has changed over the years, Ebong [1] in 1986 reported Salmonella osteomyelitis in 50% of case [1] while Thanni [2] reported S. aureus as the most common organism implicated in osteomyelitis among SCA patients in Nigeria; though SCD patients have a greater susceptibility to salmonella osteomyelitis worldwide; why this is so is not completely understood, however, SCD affects the opsonization and splenic immune protective function. A 7-year-old boy presented with fever, limb, and chest pain for 10 days; he was a diagnosed sickle-cell anemic patient who had been regular with his routine drugs and he had also received his routine vaccines. These complaints were associated with the upper chest [Figure 1] and both leg swellings; there was no history of difficulty in breathing, but he had worsening limb pains with attempted ambulation. He had an elevated white blood cell count of 35 × 109/L. The X-ray of the lower limbs and clavicles showed periosteal reaction on the medial ends of both clavicles and tibia and blood culture grew S. aureus. He made remarkable improvement after 3 weeks of antibiotic therapy. Multifocal osteomyelitis is uncommon in the general populace; however, Ebong [1] reported it in 42.6% of SCD patients; the lower limbs were mostly affected with symmetrical distribution while the tibia was the most affect bone; however, involvement of the clavicles was not reported.[1] Clavicular osteomyelitis is rare;[3],[4],[5] Chrysochoou et al.[6] reported it constituting <3% of cases of osteomyelitis in children. It may follow post-traumatic events, especially after subclavian catheter placement;[5],[6] furthermore, hematogenous spread has been implicated, as was observed in the index case. Few cases have been reported among sickle-cell anemic patients,[7] and the clinical features may be quite subtle with limited X-ray findings, and S. aureus is the most implicated organism, which was similar to our findings.{Figure 1}
