Dear sir,

First of all I want to say thank you for your questions ^[1] about our article ^[2] as it allows us to give some clarifications for better understanding of our paper:

1. The fracture was operated 4 months later the injury. The abstract report about 2 months later the injury is a mistake. About point 2,3 and 4 we think that the only explanation for the symptoms onset was narrowing of the virtual space where brachial plexus lies. No excessive screws length, neither exuberant callus, neither an hematoma were discovered during the plate removal. We only remolded the stumps of clavicle. 5. The fracture was fixed again because medial stump cause a skin ulcer. We preferred the plate because it allowed the curettage of the non-union site. We did not use other types of synthesis (intramedullary nail, etc), indeed it was a difficult case of nonunion.

Thank you and best wishes.
