Because bilateral clavicle fractures occurred in one patient, a total of nine clavicle fractures following ND were assessed using CT images. Pathological fracture due to bone metastasis or local recurrence was carefully ruled out.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>The time interval from ND to clavicle fracture ranged from 2 to 8 months (median, 4 months). On CT images, all the nine fractures occurred in the proximal clavicles and displayed increased bone marrow density with extraosseous soft-tissue mass formation. Osteolysis of the clavicle was not observed. Intra articular fractures were observed in three (33%), displaced fractures in two (22%), and free bone fragments in three (33%) cases. Further follow-up using CT showed that six (67%) fractures resulted in pseudoarthrosis. For the remaining three (33%) fractures with bone union during follow-up, the time interval between clavicle fracture and bone union ranged from 4 to 16 months (median, 6 months).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>Proximal clavicle fractures, which are rarely observed following ND, always display extraosseous soft-tissue mass formation without osteolysis.
