| Summary: | Image-guided vertebral augmentation effectively treats pathologic vertebral lesions, though managing pathology in the cervical spine presents unique challenges. Posterolateral approaches, while safer, require prone positioning that may not be feasible for all patients. Open anterolateral and transoral approaches increase infection risk and typically require general anesthesia. We present a novel multimodal anterolateral approach using ultrasound, fluoroscopy, and cone-beam CT for percutaneous C2 vertebral augmentation in a patient with metastatic lesions. A 72-year-old man with multiple myeloma presented with a C2 vertebral body lytic lesion at high risk for dislocation. Due to presence of a stabilizing cervical collar and the risk associated with prone positioning, vertebral augmentation access was limited. With the patient in supine position, we utilized cone-beam CT with overlay guidance to plan a right lateral trajectory. Ultrasound identified vital vasculature, enabling targeted hydrodissection to create a safe access path with real-time image-guidance. An 11G trocar needle was advanced under ultrasound guidance, with intermittent cone-beam CT adjustments to ensure precise placement. After confirming access to the right lateral mass of C2 via fluoroscopy, 3.5cc of PMMA cement was successfully injected without extravasation. The patient experienced no complications or neurologic deficits on follow-up and was cleared to remove the cervical collar 10 days postprocedure. This case demonstrates the feasibility and efficacy of a multimodal anterolateral approach for C2 vertebral augmentation when conventional approaches are contraindicated. By integrating ultrasound-guided hydrodissection with advanced imaging, this technique offers a safe alternative for anatomically constrained patients while avoiding the risks associated with traditional approaches. |
