History and Physical Examination

A painless mass or swelling over the clavicle is the usual presenting concern. The patient has no history of trauma, and shoulder and arm movement are normal. A family history of similar deformities is rare. Neurofibromatosis rarely is an associated diagnosis. In older children, pain is infrequent but may occur.

In the typical presentation, the larger sternal side is tilted anteriorly and superiorly, and the smaller acromial portion curves gently to meet the pseudoarthrosis. The mass usually is painless, range of motion is full, and function is normal. Café au lait lesions typically are not seen.
