To develop finite element models of spine following osteotomy and evaluate the effect of number and location of cross-links (CLs) on long-segment instrumentation. ⋯ The application of CLs enhanced the rigidity of the construct. With increased number of CLs, ROM of the construct was decreased, especially in axial rotation. CLs can also disperse the stress concentration. After comparing various CL configurations in different motion conditions, we believe that the optimal method is to place 2 CLs at the osteotomy site and the proximal segment.

Comparative Study
Comparison of Short-term Stimulation of the Globus Pallidus Interna and Subthalamic Nucleus for Treatment of Primary Dystonia.
To compare the efficacy and side effects of bilateral globus pallidus internus (GPi) and subthalamic nucleus (STN) deep brain stimulation (DBS) in the same patient with primary dystonia. ⋯ Both short-term GPi and STN stimulation improved the motor symptoms of dystonia, but there was no significant difference between GPi DBS and STN DBS. There were more side effects associated with STN stimulation.

Carotid Artery Stenting for Symptomatic Internal Carotid Artery Stenosis Associated with Moyamoya Syndrome.
Surgical intervention in a case of internal carotid artery stenosis with moyamoya vessels has not been well described. We present a case with detailed description of the surgical procedure and perioperative management. ⋯ In our patient with internal carotid artery stenosis with moyamoya vessels, strict control of blood pressure likely contributed to prevention of hyperperfusion syndrome or hemorrhagic complications.

Most surgical treatments for medically intractable temporal lobe epilepsy are helpful. When a patient has persistent symptoms after surgery, there are no tests that accurately predict whether a patient will have remnant epileptic foci. The aim of this study was to evaluate the usefulness of magnetoencephalography (MEG) as a prognostic tool in patients with temporal lobe epilepsy. ⋯ MEG can provide valuable postsurgical information on epileptic foci in patients with recurrent symptoms; GOs on postoperative MEG were especially correlated with epileptic recurrence. Our data show that GOs on postoperative MEG may have prognostic value.

Ultrasonic scalpel-assisted endoscopic endonasal surgery of infratemporal fossa: our first impressions.
The endoscopic endonasal transpterygoid approach is emerging as a valid option for treating selected tumors in the infratemporal fossa. Compared with traditional open approaches, the endoscopic endonasal approach presents more difficulty in controlling bleeding and less choice in surgical instruments for endoscopic tumor dissection, which is often performed with bipolar forceps or steel dissectors. ⋯ The ultrasonically activated scalpel is a safe, effective and simple to use device, which achieved excellent hemostasis and did not damage adjacent neurovascular structures.
