Abstract

CASE:

We describe 2 patients with nonunion of the clavicle and dynamic compression of the subclavian artery. In both patients, no structural abnormality of the subclavian vessels was evident at rest; however, with the arm in hyperabduction, arterial occlusion occurred because of the mobility of the fracture and a prominent callus.

CONCLUSION:

This small case series demonstrates an important and, to our knowledge, unreported clinical complication of clavicle fracture nonunion. We believe that this complication is worth considering as a rare but important cause of pain in patients with delayed union or nonunion of the clavicle.
