[Biplanar clavicle extension osteotomy : A case report of an extension osteotomy due to shortening of a healed clavicle fracture with sagittal split technique and corticocancellous graft].

Clavicle fractures healed in shortening or malposition are extremely rare, especially in adolescence. In extreme cases, they can result in massive pain and limitation of movement. A causal therapeutic approach is lengthening osteotomy using the sagittal split technique with tricortical iliac crest interposition.
