Sacral fractures result from high-impact trauma or in the form of insufficiency or pathologic fractures, resulting from osteoporosis, radiation therapy, or malignancy. In the emergency setting, the escalating use of computed tomography has substantially increased diagnosis of sacral fractures, which are frequently occult on radiographs. ⋯ Sacroplasty is a safe, minimally invasive treatment option for many types of sacral fractures. It provides rapid and durable pain relief, with a low incidence of complications.

ReviewPercutaneous Vertebral Body Augmentations: The State of Art.
Osteoporotic compression fractures of the vertebral body can result in pain and long-term morbidity, including spinal deformity, with increased risk of mortality resulting from associated complications. Conservative management includes opioids and other analgesics, bed rest, and a back brace. For patients with severe and disabling pain, vertebral augmentation (vertebroplasty and kyphoplasty) is often considered, with these procedures endorsed by multiple professional societies, and provides immediate structural support, and stabilizes and reinforces the weakened bone structure. The purpose of this article is to review the vertebral biomechanics, indications and contraindications, and techniques of performing successful vertebral augmentation.

The vertebral column is the most common site of osseous metastasis, and percutaneous minimally invasive thermal ablation is becoming an important contributor to multidisciplinary treatment algorithms. Continuously evolving minimally invasive image-guided percutaneous spine thermal ablation procedures have proven safe and effective in management of selected patients with spinal metastases to achieve pain palliation and/or local tumor control. This article details the armamentarium available and the most recent advances in minimally invasive, percutaneous image-guided thermal ablation for management of spinal metastases.
