Transforaminal Migration of K-Wire From Clavicle to Cervical Spinal Canal: A Case Report and Review of Literature

Introduction: Kirshner wires are commonly used for orthopedic surgical fixation for shoulder injuries, particularly around the acromioclavicular joint. They are versatile, cheap, and minimally invasive in stabilizing bone fragments. However, there have been cases of secondary migration of K-wires from the clavicle to surrounding tissues, particularly around the cervical spine.

Case report: We present a case of a 60-year-old female with left-sided neck pain and radiation to the left upper limb, a K-wire was found to have migrated through the C7-T1 foramina left side into the spinal canal posterior to the vertebral body in a transverse trajectory. The patient underwent surgical removal of the K-wire, and post-operative pain improved without neurological complaints.

Conclusion: Even though Kirshner wires are versatile, cheap, and minimally invasive in stabilizing bone fragments, but migration to unexpected anatomical sites remains a concern. This paper reviews the literature and discusses clinical presentation, diagnostic modalities, and surgical approaches related to spinal canal migration of K-wires.
