From the Guidelines
Vertebroplasty can be performed after radiation therapy for a pathological fracture of the spine, as it can provide pain relief and stabilize the vertebral body. The procedure involves injecting bone cement into the fractured vertebra, and its timing is crucial, typically waiting 2-4 weeks after radiation therapy completion to allow for initial healing and reduce complications 1. This approach can be beneficial as radiation treats the underlying malignancy while vertebroplasty addresses the structural instability.
Key Considerations
- Patients should be evaluated individually, considering factors such as the extent of the fracture, overall spinal stability, radiation dose received, and their general health status.
- Potential complications include cement leakage, infection, and bleeding, though these risks are generally low.
- Pain relief from vertebroplasty can be immediate in many cases, allowing for improved mobility and quality of life.
- A multidisciplinary approach, including interventional radiology, surgery, and radiation oncology consultation, is recommended for patients with pathologic fracture with spinal deformity or pulmonary dysfunction 1.
Additional Pain Management Strategies
- Some patients may require additional pain management strategies alongside the procedure, including analgesics or physical therapy.
- The combination of vertebroplasty with other treatments, such as radiation therapy, can have additive effects on pain relief and functional outcomes 1.
Recent Guidelines and Recommendations
- The most recent guidelines suggest that percutaneous vertebral augmentation (VA) is usually appropriate for patients with pathologic fracture with severe and worsening pain 1.
- The Spinal Instability Neoplastic Score (SINS) can be used to evaluate the stability of the vertebral body and determine the need for intervention 1.
From the Research
Vertebroplasty After Radiation Therapy for Pathological Fracture of the Spine
- Vertebroplasty can be performed after radiation therapy for a pathological fracture of the spine, as stated in the study 2.
- This procedure can be done before, after, or concurrently with most radiation and chemotherapy protocols, according to the study 2.
- The study 2 recommends vertebroplasty or kyphoplasty in properly selected patients with painful pathologic fractures as early as possible.
Benefits and Risks of Vertebroplasty
- Vertebroplasty and kyphoplasty offer patients a minimally invasive, percutaneous procedure that dramatically reduces pain related to pathologic spinal fractures almost immediately with very low complication rates, as mentioned in the study 2.
- The study 3 notes that percutaneous vertebroplasty can be beneficial for patients with vertebral osteoporotic compression fractures, but it also highlights the potential risks, such as cement leakage.
- The study 4 describes a case of successful vertebroplasty of a severe T7 collapse secondary to metastatic thymic carcinoma, which resulted in resolution of axial and radicular pain.
Effectiveness of Vertebroplasty in Reducing Pain
- The study 5 found that vertebroplasty in the cervical spine is an effective procedure for the stabilization of pathological vertebral fractures caused by multiple myeloma, leading to a statistically significant reduction of pain status.
- The study 2 mentions that visual analog scale pain scores, narcotic usage, and quality of life scales (SF-36) have all been shown to improve in a durable fashion for over 1 year after vertebroplasty or kyphoplasty.
Considerations for Vertebroplasty After Radiation Therapy
- The study 6 highlights the importance of minimizing radiation exposure to medical staff during vertebroplasty, but it does not directly address the feasibility of vertebroplasty after radiation therapy.
- However, the study 2 suggests that vertebroplasty can be performed after radiation therapy, implying that it is a viable option for patients who have undergone radiation treatment for a pathological fracture of the spine.
