Migration of a broken Kirschner wire from an acromioclavicular joint into the neck: a case reportMigration d’une broche de Kirschner cassée de l’articulation acromio-claviculaire vers le cou

Migration of Kirschner wires and Steinmann pins when they are used for internal fixation of the shoulder girdle is a known complication, which could sometimes result in life threatening situations. A case of pin breakage used for fixation of an acromioclavicular joint dislocation with subsequent migration of its medial end into the neck is presented emphasizing the fact that bending the outer end of the wire doesn’t guarantee safety and wire migration is possible after its breakage. It seems that the most reliable way to avoid this complication is close radiographic follow up of the patient and removal of wire or pin at an appropriate time.
