The interscalene brachial plexus block (ISBPB) is a most reliable and commonly performed technique for regional anesthesia of the upper extremity. It has widespread clinical applicability, ranging from use for shoulder surgery as well as diagnostic and therapeutic uses in pain management. Traditional methods described for performing the ISBPB involve identifying surface anatomy landmarks. Unfortunately, in patients with less than ideal landmarks (those with short, thick necks and those lacking adequate muscle tone in the neck area) it becomes increasingly challenging to identify these landmarks. As a result there is greater uncertainty in accurately locating the brachial plexus, and consequently greater risk in performing the block. ⋯ It is concluded that this technique represents a safe, reproducible, and highly successful method for use by anesthesiologists and pain physicians alike.

Randomized Controlled Trial
Computer-assisted guidewire insertion for hip fracture fixation.
: This study was designed to test in a laboratory setting a novel computer-assisted fluoroscopic technique and a conventional fluoroscopic technique for open reduction and internal fixation (ORIF) of hip fractures. Our hypothesis is that a novel computer-assisted fluoroscopic technique will achieve acceptable guidewire placement in one pass, with decreased fluoroscopic time and with accuracy and precision better than conventional technique. ⋯ The computer-assisted technique was significantly more accurate and precise than conventional technique. It also required fewer drill tracks through the femur and exposed the patient and the surgical team to significantly less ionizing radiation.

Retrospective clinical and intraoperative navigational data review. ⋯ Image-guided thoracoscopic spinal surgery can provide 3-dimensional orientation to a 2-dimensional imaging procedure that ultimately improves accuracy, efficiency, and safety. Future developments in combining guidance technology with standard surgical procedures will likely continue.

The introduced new developed navigation system is a High Intensity Approach Light System for augmented reality in image-guided surgery. The surgeon follows the projected approach lights with his ordinary surgical instruments. Thus, tracked instruments are not necessary with this system.
