Minimally invasive percutaneous pedicle screw instrumentation methods may increase the need for intraoperative fluoroscopy, resulting in excessive radiation exposure for the patient, surgeon, and support staff. Electromagnetic field (EMF)-based navigation may aid more accurate placement of percutaneous pedicle screws while reducing fluoroscopic exposure. We(More)
—Most current regulations allow small-scale electric generation facilities to participate in distributed generation (DG) with few requirements on power-purchase agreements. However, in this paper, it is shown that distribution companies can alternatively encourage DG investors into DG contracts that can significantly benefit the utility network. In this(More)
To understand how rapid changes in blood pressure can regulate Na-K-ATPase in the kidney cortex, we tested the hypothesis that a short-term (5 min) decrease in renal perfusion pressure will increase the amount of Na-K-ATPase in the plasma membranes by an angiotensin II-dependent mechanism. The abdominal aorta of anesthetized Sprague-Dawley rats was(More)
Cheng et al 1 have discussed using a dynamic posterior stabilization device to treat asymmetric collapse of an artificial disc in the coronal plane. Although this may correct the radiographic coronal-plane abnormality, there are significant biomechanical considerations to be kept in mind. When using these 2 devices in conjunction with each other at the same(More)
OBJECTIVE This purpose of this study was to objectively evaluate and assess the efficacy and efficiency of discectomy and endplate preparation during transforaminal lumbar interbody fusion (TLIF) using traditional manual instrumentation versus a novel suction discectomy curette. Transforaminal lumbar interbody fusion is the most widely used approach for(More)
