Deep brain stimulation electrode placement with interventional magnetic resonance imaging (MRI) has previously been reported using a commercially available skull-mounted aiming device (Medtronic Nexframe MR) and native MRI scanner software. This first-generation method has technical limitations that are inherent to the hardware and software used. A novel system (SurgiVision ClearPoint) consisting of an aiming device (SMARTFrame) and software has been developed specifically for interventional MRI, including deep brain stimulation. ⋯ This novel system provides the submillimetric accuracy required for stereotactic interventions, including deep brain stimulation placement. It also overcomes technical limitations inherent in the first-generation interventional MRI system.

ReviewGrowing trend of China's contribution to the field of plastic and reconstructive surgery: a 10-year study of the literature.
In the past decade, plastic and reconstructive surgery in China has achieved great advances. However, the scientific publications in plastic and reconstructive surgery in the major regions of China-Mainland, Hong Kong, and Taiwan are unknown. We therefore intended to reveal the contribution of articles from Chinese authors to the field of plastic and reconstructive surgery. ⋯ The number of articles published from Chinese authors increased markedly from 2000 to 2009, particularly from Mainland China, since 2004.

Comparative Study
A five to seven year follow-up comparing computer-assisted vs freehand TKR with regard to clinical parameters.
Computer-assisted knee surgery has become established in routine clinical practice. Still, there is no study investigating midterm clinical outcome after five to seven years postoperatively. We aimed to test the hypothesis that there is no difference either for subjective [Western Ontario and McMaster Universities (WOMAC) scores] or for objective (Knee Society Score, degree of flexion) criteria between computer-assisted total knee replacement (TKR) and freehand TKR after 5.6-7.3 years. ⋯ No significant differences in midterm clinical outcome were found after TKR performed in the freehand vs computer-assisted technique.

Intraoperative magnetic resonance-guided frameless stereotactic biopsies - initial clinical experience.
We present our early experience in intraoperative magnetic resonance (iMRI)-guided stereotactic frameless biopsies with special regard to its safety, efficacy and diagnostic value. ⋯ Frameless stereotactic iMRI-guided brain tumour biopsy is a safe and diagnostically effective procedure. The use of iMRI might increase the diagnostic value and safety of stereotactic biopsy and positively influence its economic balance.

Case ReportsSuperselective indocyanine green angiography for selective revascularization in the management of peripheral cerebral aneurysms.
This report describes the management of a fusiform peripheral middle cerebral artery aneurysm by endovascular parent artery occlusion under bypass protection. Localization of the recipient cortical artery was accomplished after craniotomy by superselective injection of diluted ICG dye via a microcatheter positioned proximal to the aneurysm. This report demonstrates that superselective ICG angiography can be a beneficial alternative technique to identify the best anastomosis site intraoperatively.
