Case ReportsComputed tomography-guided cement augmentation for pain relief of a symptomatic sternal fracture.
The authors report a novel application of cement augmentation for treatment of a symptomatic sternal fracture. Sternal fractures often cause debilitating pain and can affect ventilation. ⋯ The patient subsequently reported good pain relief and improved breathing. Sternoplasty may be a viable alternative for patients with sternal fractures and refractory pain.

Comparative Study Clinical Trial
Calcium-phosphate and polymethylmethacrylate cement in long-term outcome after kyphoplasty of painful osteoporotic vertebral fractures.
A comparative prospective trial evaluating 3-year outcome. ⋯ CaP cement, e.g., Calcibon, is as effective and safe as conventional PMMA-cement with regard to immediate and sustained pain reduction and improvement of mobility after kyphoplasty of patients with painful osteoporotic vertebral fractures. CaP cement has the potential of being resorbed and replaced by newly formed bone tissue; thus, it seems to be a promising alternative for PMMA also in younger patients with painful vertebral fractures.

Multicenter Study
Percutaneous sacroplasty for osteoporotic sacral insufficiency fractures: a prospective, multicenter, observational pilot study.
Sacral insufficiency fractures (SIFs) can cause low back pain in osteoporotic patients. Symptomatic improvement may require up to 12 months. Treatment includes limited weightbearing and bed rest, oral analgesics, and sacral corsets. Significant mortality and morbidity are associated with pelvic insufficiency fractures. Percutaneous injection of polymethylmethacrylate (PMMA) into the fractured ala, sacroplasty, is an alternative treatment for SIF patients. Under fluoroscopic control, 13-G bone trochars are inserted into the fractured ala while the patient is maintained under conscious sedation. Initial reports have documented safe and effective performance of sacroplasty. Yet, these uncontrolled findings do not allow any precision in estimating complication rates or expected outcome. ⋯ Sacroplasty for SIF appears to be associated with rapid and sustained pain relief in most patients with few complications. More rigorous trials are warranted to provide definitive evidence of the safety and efficacy of sacroplasty for SIFs.

Biomechanical. ⋯ This first reported technique of posterior element vertebroplasty may increase the indications and success for patients with decreased BMD who seek an interspinous implant such as the X STOP. A possible role may exist in increasing the effectiveness of such devices. However, clinical trials have yet been performed. These results demonstrate that PMMA injection in the spinous processes is effective in increasing resistance to compressive forces in an X STOP model.

Sacroplasty by CT and fluoroscopic guidance: is the procedure right for your patient?
Sacral insufficiency fractures are an infrequent but often disabling cause of severe low back pain. We report our results of a sacroplasty technique, using CT for needle placement and fluoroscopy to monitor the polymethylmethacrylate injection in a group of patients with sacral insufficiency fractures. ⋯ Sacroplasty is a safe and effective procedure in the treatment of sacral insufficiency fractures that can provide substantial pain relief and lead to a better quality of life.
