Condensing osteitis of the clavicle in children.
OBJECTIVE
To confirm the rarity of this disorder and then to evaluate the effects of antibiotic treatment alone and assess whether this could produce a complete remission of symptoms in children and adolescents.


METHODS
We made a retrospective review of all cases of condensing osteitis of the clavicle in children and adolescents between January 2007 and January 2016. Outpatient and inpatient medical records, with radiographs, magnetic resonance imaging, triphasic bone scan and computed tomography scans were retrospectively reviewed. All the patients underwent biopsy of the affected clavicle and were treated with intra venous (IV) antibiotics followed by oral antibiotics.


RESULTS
Seven cases of condensing osteitis of the clavicle were identified. All the patients presented with swelling of the medial end of the clavicle, and 5 out of 7 reported persisting pain. The patients' mean age at presentation was 11.5 years (range 10.5-13). Biopsy confirmed the diagnosis in all cases. All the patients completed the treatment with IV and oral antibiotics. At last follow-up visit none of the patients complained of residual pain; all had a clinically evident reduction in the swelling of the medial end of the affected clavicle. The mean follow-up was 4 years (range 2-7).


CONCLUSIONS
Our findings show that condensing osteitis of the clavicle is a rare condition. Biopsy is needed to confirm diagnosis. The condition should be managed with IV and oral antibiotics. Aggressive surgery should be avoided.
