Radiofrequency ablation in combination with osteoplasty in the treatment of painful metastatic bone disease.
To evaluate the feasibility and effectiveness of combining radiofrequency (RF) ablation and osteoplasty for pain reduction in the treatment of painful osteolytic metastases. ⋯ RF ablation and osteoplasty can be combined within one session and is both feasible and useful for the treatment of osteolytic bone metastases with regard to pain relief.

Cavoatrial junction and central venous anatomy: implications for central venous access tip position.
To quantify the anatomic relationships of the cavoatrial junction and propose a system for describing central venous access device tip location on the basis of structures visible on chest radiographs. ⋯ A more accurate understanding of the superior vena cava anatomy is essential for the correct interpretation of central venous access device position. The true cavoatrial junction is located more inferiorly than commonly believed and is not accurately estimated with commonly used imaging landmarks. A point two vertebral body units below the carina enables the reliable estimate of the position of the cavoatrial junction. Catheter tip position can be most reliably described in vertebral body units below the carina, with use of the thoracic spine as an internal ruler.
