Continuous Injection of Large Volumes of Cement Through a Single 10G Vertebroplasty Needle in Cases of Large Osteolytic Lesions

To the editor,
Since its first description in 1987, percutaneous cementoplasty has been successfully applied to treat both painful osteoporotic/malignant spinal compression fractures and painful extra-spinal bone metastases . For spinal cases, the amount of cement required for clinical improvement and mechanical stabilisation usually does not exceed 10 ml . For extra-spinal cases, there is usually a need for larger volumes of cement . Even though the clinical outcome in terms of pain alleviation does not seem to be related to lesion filling, most of the authors advocate injecting as much cement as possible to provide optimal mechanical stabilisation. There is only scarce literature available on the technique to inject large volumes (> 10 ml) of cement . A systematic review reported that such injection was usually achieved through the insertion of multiple needles inside the lesion . We recently performed the injection of large volumes of cement through a single puncture...
