Migration d'une broche dans le canal médullaire cervical après une ostéosynthèse de l'articulation acromio-claviculaire

We report the case of a 49 year-old right-handed chef with left shoulder trauma occurred during a football game. The diagnosis was fracture of the distal quarter of clavicle. The patient underwent osteosynthesis using cerclage wire and splint . The patient suffered from pain and hypoesthesia with a deficit in C8-T1 interosseous territory; radiographs objectified pin migration to the cervical spine. It pierced left C7-T1 vertebral foramen contacting the medullary sheath with consequent threat to vital or functional prognosis. The patient underwent urgent removal of osteosynthesis material in the Department of Neurosurgery. The evolution was marked by the disappearance of neuralgia and an acceptable functional recovery. Osteosynthesis using cerclage wire and splint is a major surgical technique for fractures of the distal quarter of clavicle or acromioclavicular disjunctions. Its main complication remains pin migration.
