Book Description
As an alternative to current guidance systems we have investigated the possibility of an ultrasound based device for pedicle screw guidance. Ultrasonic measurements on seven vertebral cancellous bone specimens were performed along the craniocaudal axis using a water immersion system with unfocussed 1 MHz and 3.5 MHz broadband transducers. The center frequency attenuation, normalized broadband ultrasound attenuation (nBUA), and phase speed were measured. Pulse echo methods were used to show A-mode imaging through the cancellous bone samples by demonstrating detection of a reflector placed on the opposite end of the bone. Furthermore, we performed a preliminary evolution of a 3-D simulator (Wave3000) for studying the propagation of ultrasound in cancellous bone. Our in vitro results provide good evidence that A-mode imaging for pedicle screw guidance is possible at frequencies as high as 3.5 MHz and that boundaries can be identified to an accuracy of approximately 1 mm.

Book Description
This thesis describes the design and fabrication of ultrasound probes for pedicle screw guidance. The author details the fabrication of a 2MHz radial array for a pedicle screw insertion eliminating the need for manual rotation of the transducer. He includes radial images obtained from successive groupings of array elements in various fluids. He also examines the manner in which it can affect ultrasound propagation.

Book Description
Percutaneous lumbar discectomy is a new surgical method for treating lumbar disc diseases. The goal of the procedure is decompression of the spinal nerve root by percutaneous removal of the nucleus pulposus under local anesthesia. Probably 20 % of all patients requiring lumbar disc surgery can be successfully treated by this method. During the past two years, percutaneous discectomy has spread rapidly, and it is now performed in most clinical departments engaged in spinal surgery. The first International Symposium on Percutaneous Lumbar Discectomy, held in Berlin in August 1988, covered all current procedures known as "percutaneous discectomy" and the entire range of percutaneous techniques, both clinical and experimental. Its publication is important because of the recency of this new surgical procedure, the outstanding experience of the speakers - including the Japanese, American, and European "pioneers" of the technique - and last but not least the gaps in the knowledge of physicians concerning this topic. This procedure opens up new perspectives in the surgical treatment of degenerative diseases of the lumbar spine.

Book Description
Minimally Invasive Spine Surgery combines up-to-date research on surgical techniques with high-definition surgical video and concise algorithmic evidence. Each of its sixteen chapters begins with a brief summary followed by imaging indications, instrumentation, a step-by-step surgical technique (and video guide), as well as the potential complications and adverse outcomes that may develop. Techniques discussed in the text include: Posterior Cervical Foraminotomy; Percutaneous Posterior Pedicle Screw Placement; Lumbar Discectomy; Transforaminal Lumbar Interbody Fusion (TLIF); Lateral Lumbar Interbody Fusion (LLIF). Also included is a discussion on the types of implants and instrumentation available today and the potential advantages they offer, making Minimally Invasive Spine Surgery an essential and relevant book for orthopaedic and neurosurgeons. Key Points Authored by experts from Rush University Medical Centre and Thomas Jefferson University Hospital in the United States Includes DVD to enhance clinical instruction 273 full colour illustrations

Book Description
Intraoperative imaging technologies have taken an ever-increasing role in the daily practice of neurosurgeons and the increasing attention and interest necessitated international interaction and collaboration. The Intraoperative Imaging Society was formed in 2007. This book brings together highlights from the second meeting of the Intraoperative Imaging Society, which took place in Istanbul-Turkey from June 14 to 17, 2009. Included within the contents of the book is an overview of the emergence and development of the intraoperative imaging technology as well as a glimpse on where the technology is heading. This is followed by in detail coverage of intraoperative MRI technology and sections on intraoperative CT and ultrasonography. There are also sections on multimodality integration, intraoperative robotics and other intraoperative technologies. We believe that this book will provide an up-to date and comprehensive general overview of the current intraoperative imaging technology as well as detailed discussions on individual techniques and clinical results.

Book Description
A unique how-to guide for spine surgeons on state-of-the-art computer-assisted navigation and robotic surgery techniques The past decade has seen major advances in image-guided spine surgery techniques, with robotically assisted approaches emerging in the last five years. While early adopters of this technology paved the way for more widespread use of navigated and robotic systems, barriers still exist. Navigation and Robotics in Spine Surgery by master spine surgeon Alexander Vaccaro and esteemed co-editors Jaykar Panchmatia, I. David Kaye, and Srinivas Prasad addresses existing issues such as the perception of increased upfront costs, intrusion on current workflow, and a lack of understanding about the potential ways these technologies can enhance the surgical experience and improve patient outcomes. Organized into six sections, the book starts with evidence-based fundamentals of navigated spine surgery and robotics including discussion of instrumentation and mechanics. Sections 2-5 serve as a surgical handbook for spine surgeons who wish to introduce these technologies into practice or augment their current repertoire with more complex techniques. Topics range from more routine procedures such as navigated and robotic minimally invasive TLIF to complex approaches like intraoperative ultrasound guided intradural spinal tumor resection. The final section looks at future directions and potential new applications for these technologies. Key Highlights An impressive group of international spine surgeons who pioneered navigation and robotic surgery techniques share invaluable tricks of the trade Discussion of fluoroscopy- and intraoperative CT-based platforms, applications for intraoperative sonography, and radiation exposure and minimization strategies Special topics include OR set-up and workflow, surmounting the learning curve, artificial intelligence, and lessons learned from other industries Procedural videos demonstrate the benefits of computer-assisted navigation and robotic techniques This book is essential reading for orthopaedic surgery and neurosurgery residents and spine fellows who wish to learn about and incorporate these technologies into practice. Seasoned spine surgeons seeking to expand the scope of their navigated/robotic practice will benefit from chapters detailing advanced approaches.

Book Description
This book covers the content of European postgraduate spine surgery courses, using a case-based approach. It describes a stepwise solution to a real-world clinical problem and compares this with the best available evidence. It then provides suggestions on how to bridge the gap (if there is one) between standard of care and evidence-based medicine. Spine Surgery: A Case-Based Approach is aimed at postgraduate students of spine surgery (both trainee neurosurgeons and trainee orthopedic surgeons), and is also of interest to medical students.
