Understanding physician responsibilities and limitations for drug and device off-label use.
Facial plastic surgery, by its nature, is a field that constantly is seeking new and innovative ways of treating patients. This innovation often involves novel techniques and tools. ⋯ Physicians are able to use drugs and devices off-label but are required to follow certain guidelines. This article describes the physician's legal responsibilities and limitations in off-label drug or device use.

During the last decade navigation techniques in pelvic and acetabular surgery have been described. Nowadays, available techniques include CT-based navigation, 2D C-arm navigation and 3D C-arm navigation. The main indication is the navigated percutaneous SI screw fixation, but acetabular screw fixations are also reported. In this article, based upon a literature review and our own clinical experiences, the indications for and limitations of navigated techniques in pelvic and acetabular surgery are described.

Randomized Controlled TrialComputed tomography-fluoroscopy image integration-guided catheter ablation of atrial fibrillation.
This study examines the feasibility of atrial fibrillation (AF) ablation using registered three-dimensional computed tomography (CT) images of the left atrium with fluoroscopy. ⋯ CT-fluoroscopic-guided left atrial ablation is feasible and allows appropriate catheter manipulation in the left atrium.

Randomized Controlled TrialComputer navigation versus conventional total knee replacement: no difference in functional results at two years.
We previously compared the component alignment in total knee replacement using a computer-navigated technique with a conventional jig-based method. We randomly allocated 71 patients to undergo either computer-navigated or conventional replacement. An improved alignment was seen in the computer-navigated group. ⋯ At two years postoperatively, the frequency of mild to severe anterior pain was not significantly different (p = 0.818), varying between 44% (14) for the computer-navigated group, and 47% (14) for the conventionally-replaced group. The Bartlett Patellar score and the Oxford knee score were also not significantly different (t-test p = 0.161 and p = 0.607, respectively). The clinical outcome of the patients with a computer-navigated knee replacement appears to be no different to that of a more conventional jig-based technique at two years post-operatively, despite the better alignment achieved with computer-navigated surgery.
