Orthopaedic Surgery, 9(1), 129-132.1757-78531757-7861https://doi.org/10.1111/os.12317https://onlinelibrary.wiley.com/doi/10.1111/os.12317http://hdl.handle.net/11452/33482Posterior instrumented fusion of the cervical spine is a common surgical procedure in the treatment of cervical subluxation, fractures, and stenosis. Although malpositions are commonly seen, it is rare to observe the malposition of the rod or interconnection because of hardware failure. A 62-year-old woman with spastic tetraparesis as a sequel to pediatric meningitis with C-1-C-2 cervical subluxation and myelomalacia had undergone laminectomy of C-1 and C-1 lateral mass and C-2 bilateral pedicular screw fixation. Three years after the stabilization, she presented with complaints of headache, neck pain, and difficulty walking. There was no history of trauma during that period. A previously unrecorded and unusual migration of a rod through the thoracic subarachnoid space was detected. In this study, we report a case of atlantoaxial stabilization using the screw-rod technique that was followed by rod migration to the thoracic subarachnoid space, and outline the subsequent management of the case. Failure of bony fusion can result in micromotion and subsequent migration of fixation device components. Routine radiographic follow-up could be used to identify migration events.eninfo:eu-repo/semantics/openAccessOrthopedicsAtlantoaxial stabilizationCervical stabilizationComplicationMigrationPosterior cervical stabilizationCervical-spineScrew fixationPosteriorComplicationsFusionAtlanto axial jointBone screwsCervical vertebraeEquipment failureFemaleForeign body migrationHumansLaminectomyMagnetic resonance imagingMiddle agedRadiographySpinal fusionSubarachnoid spaceTomographyX-ray computedReview0003982142000192-s2.0-85016410051291329128371499OrthopedicsCervical Dislocation; Cervical Spine; Pedicle ScrewsAdultArticleCase reportCervical spine dislocationCervical spine radiographyComputer assisted tomographyFemaleFollow upHeadacheHumanLaminectomyMedical device complicationMeningitisMiddle agedMyelomalaciaNeck painNuclear magnetic resonance imagingPedicle screwPostoperative periodQuadriplegiaRod migrationSpinal cord diseaseSpine fusionSpine fusion implantSpine stabilizationSubarachnoid spaceSurgical techniqueTreatment failureWalking difficultyAdverse effectsAtlantoaxial jointBone screwCervical vertebraDevice failureDevicesDiagnostic imagingForeign body migrationProceduresRadiographySubarachnoid spaceX-ray computed tomography
