Asymptomatic spinal canal migration of clavicular K-wire at the cervicothoracic junction.

Abstract

Unstable clavicular fractures can be treated surgically with pins and wires or with plates. The migration of metallic devices such as Kirschner wires (K-wires) from the shoulder to a variety of anatomical proximal and distal locations is well documented. Spinal migration, however, is rare and is normally associated with severe spinal injury. This article presents the case of a man who presented with cervicothoracic migration of a K-wire after treatment of a clavicular fracture sustained during a sports accident. The distinctive feature in this case, when compared to the existing literature, is its fortuitous detection by imaging studies and its surgical removal without neurological sequelae.
