[en] Spinal metastasis are a daily challenge in clinical practice. Stereotactic body radiotherapy (SBRT) allows delivery of definitive treatment with excellent long-term control rates. Its implementation needs dedicated devices and day-to-day image-guided radiotherapy (IGRT). The XSight™ spine tracking system, integrates with the CyberKnife® (Accuray™), provides a fiducial-free tracking system for spinal SBRT. We report a rare case of tracking failure during treatment due to the occurrence of a vertebral compression fracture (VCF). [fr] Les métastases vertébrales sont un défi quotidien en pratique clinique. La radiothérapie stéréotaxique (SBRT) permet de délivrer un traitement à visée ablative avec d’excellents taux de contrôle à long terme. Son implémentation nécessite des appareils dédiés et une imagerie de repositionnement (IGRT) quotidienne. Le « XSight™ spine tracking system », intégré avec le CyberKnife® (Accuray™), permet un « tracking » sans repère fiduciel pour la radiothérapie stéréotaxique vertébrale. Nous rapportons ici un cas rare d’échec de « tracking » en cours de traitement dû à l’apparition d’une fracture-tassement vertébrale.
