The migration of surgical wires and pins placed for repair of orthopedic injury is well recognized. Such migration usually follows a retrograde path and the wires protrude near their entry point into the native bone. Occasionally, the migration occurs in an antegrade manner and produces injury. We describe a case where three Steinmann pins placed for fixation of a humeral neck fracture migrated, one slipping backwards towards the humeral entry point and two pins migrating into the thorax.
