Review Case Reports
Intradural cement leakage: a devastatingly rare complication of vertebroplasty.
The aim of this case report is to examine the devastating complication that may follow vertebroplasty. ⋯ Percutaneous vertebroplasty with polymethyl methacrylate is relatively safe, but it still should be proceeded under careful safeguard. The needle tip should not cross the medial border of the pedicle on the anteroposterior view before it has crossed the posterior cortex of the vertebral body on the lateral view. Good quality of image monitoring and clear visualization of cement should be helpful to prevent complications.

Randomized Controlled Trial
Effect of prone positioning systems on hemodynamic and cardiac function during lumbar spine surgery: an echocardiographic study.
Prospective randomized study of patients undergoing spine surgery. ⋯ Adequate fluid replacement reduced hypotension and hemodynamic instability after prone positioning. The Jackson spine table and longitudinal bolsters had minimal effects on cardiac function, and should be considered in patients with limited cardiac reserve.

Retrospective case study of 13 cases of Paget sarcoma of the spine accrued from a prospectively collected Tumor Registry database. ⋯ This series confirmed that Paget sarcoma of the spine has a very poor prognosis. We found a constellation of symptomatology in patients with sarcomatous Paget spine resulting from radiculomedullary compression, primarily lumbosacral involvement and predominantly osteosarcomatous histology. There was no significant difference observed on the overall prognosis of the patients with Paget sarcoma of the spine in the last 6 decades.

This is a retrospective study of patients with cervical myelopathy resulting from adjacent-segment disease who were treated by open-door expansive laminoplasty. ⋯ Moderate neurologic recovery was obtained after open-door laminoplasty in patients with cervical myelopathy resulting from adjacent-segment disc disease, although the results were not as satisfactory as those in the control group. This may be attributed to the irreversible damage of the spinal cord caused by persistent compression at the adjacent segments.

Case Reports
A novel "four-rod technique" for lumbo-pelvic reconstruction: theory and technical considerations.
Surgical technique with case example. ⋯ Longer follow-up is necessary, and biomechanical and finite element studies are needed to show long-term efficacy of this technique, however, early results indicate that such a construct is feasible. Furthermore, depending on the general medical condition of the patient, immediate postoperative weight bearing is possible and reasonable.
