Asymptomatic migration of Kirschner wire into the cervical spine: a rare case report complication 32 months post-clavicle fracture fixation

Introduction and importance: Kirschner wires (K-wires) are widely used in orthopedic surgery for fracture fixation and joint stabilization, but complications such as migration, though rare, can have severe consequences. Case presentation: We report the case of a 24-year-old female who presented with asymptomatic migration of a K-wire into the cervical spine, 32 months after clavicle fixation. Imaging revealed that the wire had traversed from the right first rib to the C6–C7 interlaminar space. Surgical removal was performed via a posterior medial approach after an initial posterolateral dissection failed. Postoperative recovery was uneventful, with no complications or neurological deficits. Clinical discussion: This case marks the 14th reported instance of spinal K-wire migration and the first involving an asymptomatic female patient. Conclusions: It underscores the importance of careful surgical technique, routine follow-up, timely hardware removal, and the role of advanced imaging in detecting and managing such rare but potentially serious complications.
