Journal of Orthopaedic Trauma: March-April 1999 - Volume 13 - Issue 3 - p 222-225 Buy Abstract Fractures of the medial third of the clavicle are the rarest of all clavicle fractures. We present two cases of medial clavicle fracture nonunions that were initially thought to be chronic anterior sternoclavicular dislocations and describe the entity of pseudo-dislocation of the sternoclavicular joint. Computed tomography should be performed on all patients with suspected or established injuries of the sternoclavicular region to ensure differentiation between fracture and dislocation. © 1999 Lippincott Williams & Wilkins, Inc.
