WELCOME TO TORONTO!

froM THe MaYor of ToronTo

It is my pleasure to extend greetings and a warm welcome to everyone attending the 23rd Annual Meeting of the North American Spine Society (NASS). NASS is an organization comprised of nearly 5,000 multidisciplinary medical professionals dedicated to fostering the highest quality, evidence-based, ethical spine care through education, research and advocacy. In support of NASS' mission to promote education, this meeting is an excellent opportunity to exchange knowledge and information with leading experts, discuss new research and current trends, and network with friends and colleagues. Toronto is the largest city in Canada and the fifth largest city in North America. It is Canada's media, business, tourism, sport and entertainment capital and holds the enviable title of the world's most multicultural city. It is an amazing city built with the limitless imagination of its people, and we are thrilled to share it with our out-of-town guests and those visiting our city for the first time. On behalf of the Toronto City Council, I congratulate the organizers and wish everyone an enjoyable and informative meeting. Yours Truly, Mayor David Miller

It is with great pleasure that I extend my warmest greetings to all those attending the North American Spine Society's 23rd Annual Meeting in Toronto. This event is one of the premier continuing education meetings for spine care specialists in North America that gives researchers and practitioners a forum in which to exchange information about the newest and most promising developments in the field. I am certain that delegates will benefit greatly from the many workshops and courses available at this multidisciplinary gathering, and will leave the conference inspired to put what they learn into practice. I would like to commend everyone involved with the North American Spine Society, including all those who have worked to make this year's conference such a success. You can take great satisfaction in knowing that your efforts to advance quality spine care through education, research and advocacy have made a real difference in helping people with spinal disorders and injuries live to their highest potential as individuals. On behalf of the Government of Canada, please accept my best wishes for an enjoyable and productive meeting. The Rt. Hon. Stephen Harper, P.C., M.P.

earned reputation as an expert on knocking off highly-ranked opponents. After his departure from Notre Dame following the 1996 season, he joined CBS Sports' College Football Today for two seasons as a sports analyst. From there he went on to be head coach at the University of South Carolina from 1999-2004 where he led the Gamecocks to back-to-back January 1st bowl games for the first time in the history of the school. Holtz currently serves as a college football studio analyst on ESPN. He appears on ESPNEWS, ESPN College GameDay programs and SportsCenter, and serves as an on-site analyst for college football games. For many years, Holtz has been considered among the greatest speaking legends in the United States. He speaks about overcoming challenges by setting one's own goals and working to achieve them. Holtz has authored three New York Times bestselling books: The Fighting Spirit in 1988, Winning Everyday: A Game Plan For Success in 1998, and most recently, Wins, Losses and Lessons in 2006. Lou has produced three highly acclaimed motivational videos and was named Man of the Year in 1998 by the Walter Camp Football Foundation. Keynote address Tim Sanders Thursday, October 16, 1:00­1:45 p.m. Constitution Hall Topic: The Likeability Factor: How to Boost Your L-Factor and Achieve Your Life's Dreams Tim Sanders, former Chief Solutions Officer at Yahoo!, is an irrepressible advocate for good values in the business world. In the face of the deplorable behavior found in certain segments of the business world-- the shortsighted focus on instant profits and the tendency to fire rather than invest in employees--he advocates for an honest, ethical analysis of business realities with a straightforward program for improvement. Tim Sanders' first book, Love is the Killer App, shows how people who share generously can achieve professional success. It was both a New York Times

Welcome reception The Welcome Reception marks the official start of the Annual Meeting on Tuesday, October 14, from 6:00­8:30 p.m. in the Concert Hall of the Fairmont Royal York Hotel. This is an opportunity to see familiar faces and meet new colleagues. presidential Guest Speaker Coach Lou Holtz Wednesday, October 15, 9:00­9:45 a.m. Constitution Hall Topic: Game Plan for Success Lou Holtz has established himself as one of the most successful college football coaches of all time. Holtz earned a Bachelor of Science degree in History from Kent State in 1959 and a Master's degree from Iowa in Arts and Education in 1961. Holtz was a linebacker at Kent State for two seasons before an injury ended his football playing career. Holtz went on to coach, and became the only coach in the history of college football to take six different teams to bowl games to win five bowl games with different teams, and to have four different college teams ranked in the final Top 20 poll. Holtz has a 243-127-7 career record that ranked him third in victories among active coaches and eighth in winning percentage. His 12 career postseason bowl victories rank him fifth on the all-time list. Most notably, Holtz became the 27th head coach at Notre Dame in 1985, following two seasons at Minnesota (1984­85), seven at Arkansas (1977­83), four at North Carolina State (1972­75) and three at William & Mary (1969­71). He spent the 1976 season as head coach of the New York Jets of the NFL. Of the 26 collegiate teams he coached, 21 earned postseason bowl invitations, 14 finished in the final AP Top 20, and eight finished in the Top 10 (not including the 1995 finish in that category). Holtz enhanced his track record quickly at Notre Dame, needing only two years to put the Fighting Irish in a major postseason bowl game for the first time in seven seasons. Holtz also developed a well18 NORTH AMERICAN SPINE SOCIETY

and an international bestseller. His second book, The Likeability Factor, explores four aspects of likeability that can be measured and improved: friendliness, relevance, empathy and realness. The book was the basis for television specials on PBS and 20/20. Sanders has deep experience in cutting-edge businesses, most recently as a senior-level executive at Yahoo!, serving as their Leadership Coach. Prior to that he served as Yahoo!'s Chief Solutions Officer, overseeing next generation marketing programs to world-class brands. Sanders also created and led the Yahoo! ValueLab, an in-house "think tank" that delivered value-added propositions to prospective and current clients. Sanders is one of the United States' most soughtafter keynote speakers. He has been endorsed by Tom Peters, a leading expert on business management practices. Sanders has electrified audiences of 50 to 50,000 at leadership executive summits, user and sales conferences and major association events. Participants tell him repeatedly that his presentations are life-changing. Sanders developed and honed his speaking skills as a competitive debater, winning national debate and public speaking championships. Are you wondering how you can improve your relationships with your friends and family? Are you curious about how to get or keep the job of your dreams? Tim Sanders will show you how to raise your "likeability factor." Sanders argues that life is a series of popularity contests. The choices other people make about you determine your health, wealth and happiness. Decades of research prove that people choose who they like. They vote for them, they buy from them, they marry them, and they spend precious time with them. The good news is that you can arm yourself for the contest and win life's battles for preference. How? By being likeable. The more you are liked, or the higher your "likeability factor," the happier your professional and personal life will be.

Kitab, MD Iraq stands as a distinct country with distinct culture and civilizations. However, Iraq's recent history has witnessed major war conflicts that have had catastrophic effects on human health and wellbeing. During the last 30 years, the impacts of war and the diversion of financial, human and natural resources for military purposes have taken their remarkable effects upon the general health care system. Spine care in Iraq linked with the general health system is consequently adversely affected; it is in need of emergency care and redesign. Modernizing the quality and content of spine care in Iraq calls for the help and expert opinion from all over the world.

OFFICIAL PROGRAM SCHEDULE

SiG: Methods to Minimize Wrong level Spinal Surgery Room 205 D Moderator: Ross Moquin, MD Government and payer oversight of medicine is increasing, with wrong site and level of surgery as a specific concern. Spinal surgery has the inherent difficulty of levels in close proximity with, at times, ambiguous landmarks for localization. No clear recommendations to minimize the risk of wrong level surgery have come from organized spine surgery. Different methods and their rationale and ways in which organized spine surgery can offer intra-operative localization guidelines for the practicing spinal surgeon are discussed. SiG: integrating Chiropractic Care into a Multidisciplinary Spine practice Room 206 A Moderator: Gayle Jasinski, DC The utilization of chiropractic services for spinal complaints has grown extensively in the past two decades. Many of our spine care patients can benefit from the utilization of chiropractic services. During this SIG several questions are discussed, including: 1) How can we better incorporate chiropractic care into a multidisciplinary approach to spine care? and, 2) What role, if any, can or should a chiropractor play in evaluating and managing nonsurgical and even postsurgical spine patients? 5:20­6:20 p.m. Sipp 1: arthroplasty Room 206 B Moderator: Paul A.

OFFICIAL PROGRAM SCHEDULE

8:07­8:25 a.m. Discussion 8:25­9:55 a.m. Symposium: an Update and evolution in the Treatment of Cervical Disc Disease Constitution Hall Moderator: Alexander J. Ghanayem, MD The surgical and nonsurgical treatment of cervical disc disease has historically been associated with positive, predictable outcomes. However, closer attention to dissatisfaction from the patients' and physicians' perspectives has led to enhancements in treatment algorithms and implant design, the evolution of biologics, and global shifts in thought processes in fusion and non-fusion options.

Symposium SiG: Update on Biologics and Basic research for Spinal Disorders (See symposium description on page 55) Room 206 DF Moderator: Jeffrey C. Wang, MD SiG: The emergence of internet Based peer to peer Collaboration in Surgical Decision Making Room 202 A Moderator: Paul J. Slosar, Jr., MD Few opportunities exist for physicians to obtain immediate or direct advice from peers on complicated cases. Physicians may rely on resources that are not applicable to a unique surgical problem. Recently, Reynolds et. al studied the effect of peer collaboration among surgeons at a weekly surgery conference. They found that changes in surgical decision-making occurred in 12.5% of all cases reviewed and in 20% of the complex cases. The internet has introduced Collaborative Knowledge Networks (CKNs) that allow communities of surgeons to virtually collaborate on complex patient cases--allowing for rapid, bidirectional information. This SIG discusses if internet based, spine-surgeon collaborative websites will alter surgical decision making and impact the adoption of new techniques. SiG: Managing Conflict of interest with Disclosure Room 205 B Moderators: Stanley A. Herring, MD Marjorie Eskay-Auerbach, MD, JD Recent press releases have brought the issue of Conflict of Interest (COI) to the forefront. In the current environment, these conflicts are best managed by full disclosure. NASS has taken the lead in addressing disclosure issues as management of COI evolves. This SIG discusses the issues that surround disclosure and use of disclosure as a way to manage COI.

8:07­8:25 a.m. Discussion 8:25­10:10 a.m. Symposium: applying evidence-based Medicine into Your practice Constitution Hall Moderator: Christopher M. Bono, MD Navigating through the expanding world of spine literature has become increasingly complex. Faced with this complexity, spine practitioners are called to make sound clinical decisions based on the best available scientific data, rather than relying only on training practices or personal experience. This process is best guided by sound application of the principles of evidence-based medicine (EBM). However, not all physicians are familiar with or proficient in these principles. This symposium offers the practicing spine physician a practical guide to understanding basic principles of EBM. Specifically, sessions include discussions on rating levels of evidence, understanding bias in randomized controlled trials (RCT), using the "best available evidence" for clinical decision-making, and balancing the role of experience with strict EBM interpretation. In addition, there will be a live, online demonstration of the PubMed/Medline Database within the framework of a systematic review to answer a specific clinical question. Though an in-depth statistical review is beyond this symposium's scope, the speakers discuss the concept of study power, alpha and beta error, and the significance of confidence intervals. The symposium concludes with a case-based panel discussion to demonstrate reasonable and judicious use of EBM in actual clinical scenarios.

Upon completion of this symposium, participants should be able to: · Appraise the available literature through performing their own informal systematic reviews targeted at answering practical clinical questions and rating articles for their level of evidence (I-V). · Cite basic statistical principles used to determine the validity of comparisons between different treatment types, e.g. does reporting a statistical difference always mean a "real difference"? · Distinguish between a high-quality RCT that provides true level I evidence from lower-quality studies that, despite sharing the title "RCT", provide only level II or III evidence. · Select the best available data upon which to make clinical decisions, particularly in scenarios for which there are no relevant RCTs and the best evidence might be level IV, retrospective data. · Introduction: What is Evidence-based Medicine Christopher M.

OFFICIAL PROGRAM SCHEDULE

1:00­3:00 p.m. Symposium: lessons learned from Disc arthroplasty Constitution Hall Moderators: Paul A. Anderson, MD A. Seth Greenwald, PhD Understanding the basic science of wear, lubrication and the inflammatory responses from wear debris is essential to treat patients with disc replacement. This science is called tribology, which is largely unfamiliar to spinal surgeons. Many of the advances in tribology have been learned from joint arthroplasty, with these principles being repeated in spinal arthroplasty. Because it is likely that the long-term failure of disc replacement devices will be related to their wear performance, increased knowledge by surgeons of the principles of tribology is necessary. This belief was imparted to the lead author by basic scientists involved in scholarly research of joint arthroplasty, who strongly believed that few spinal surgeons were aware of this body of knowledge. The knowledge gained from this symposium enables surgeons to choose the best device for a patient and to potentially identify problems related to wear at an early stage. Upon completion of this symposium, participants should be able to: · Explain basic principles of tribology: the science and technology of friction, lubrication and wear. · Assess standard methods to test wear of total disc prostheses and their limitations. · Recognize wear-related problems in patients. · Evaluate the basic science of total disc arthroplasties to be able to choose the best device for a patient. · Lumbar and Cervical Spinal Disc Arthroplasty: The Need Defined Dennis P.

SiG: The Sacroiliac Joint: an Updated Understanding Room 205 D Moderator: John G. Stark, MD Though sacroiliac joint (SIJ) pain is not a new problem, understanding and study of it has lagged behind other causes of low back pain of equivalent or lesser impact. It is increasingly apparent that SIJ problems are a cause of failure and recurrent back pain in patients with otherwise successful surgery. Literature suggests the prevalence of SIJ-related pain is close to 20%. If these figures are accurate, the sequelae of wrong-site surgery are very serious concerns, especially given the number of practitioners who remain unfamiliar or uncomfortable with the diagnosis. This SIG discusses the lack of awareness which carries a high cost to patients, who are often subjected to surgery which may exacerbate an already painful condition.

To maintain the integrity of professional judgment of our members, volunteers and leaders, and to maintain public confidence, NASS has adopted a policy of uniform disclosure of financial conflicts of interest. Therefore, anyone speaking at the Annual Meeting must provide complete disclosure of all conflicts of interest. NASS recognizes that professional relationships with industry are essential for the development of new spine technologies and medical advancement. These relationships in no way reflect negatively on the character of the individual. The intent of this policy is to require disclosure of situations in which there is even the potential for bias, without any implications regarding actual bias. The establishment of uniform disclosure requirements frees individuals from having to decide which relationships might influence his or her decisionmaking and which are irrelevant; transparent disclosure allows the audience to participate in the interpretation of the significance. Disclosure information will be made available visually on a PowerPoint® slide before each presentation, in the Final Program, orally by the moderator and in The Spine Journal Proceedings supplement. fDa Disclosure If a device or drug requiring FDA approval is identified as an important component of a presentation, the author must indicate the FDA status of those devices or drugs as Approved, Investigational or Not Approved for distribution within the United States. This Final Program and The Spine Journal Proceedings supplement includes all FDA status information. Certain medical devices and drugs identified at the 23rd Annual Meeting may have FDA clearance for use for specific purposes only or in restricted research settings. The FDA has stated it is the responsibility of the physician to determine the FDA status of each drug or device he or she wishes to use in clinical practice and to use these products in compliance with applicable law. Commercial Support Disclosure All individuals participating in a sponsored activity are required to disclose to the audience all financial interests or other relationships (1) with the manufacturer(s) of any commercial product(s) and/or provider(s) of commercial services discussed in an educational presentation, and (2) with any commercial supporter(s) of the activity. Financial interests or other relationships may include: grants or research support, employee consultation, shares in a company, member of a speaker's bureau, etc. The intent of this disclosure is to ensure that all conflicts of interest, if any, have been identified and have been resolved prior to the speaker's presentation. By doing so, the North American Spine Society has determined that the speaker's or author's interests or relationships have not influenced the presentation and/or electronic poster with regard to exposition or conclusion; the Society does not view the existence of these interests or commitments as necessarily implying bias or decreasing the value of the presentation.

Since its start in 1985, NASS has grown to nearly 5,000 members in 24 spine-related specialties. NASS fulfills its mission to advance spine care through a variety of programs designed to meet the needs of spine providers. The NASS Annual Meeting attracts an international audience by offering symposia featuring worldrenowned experts speaking on surgical, medical and interventional care; paper presentations announcing results of research on new techniques, treatments, devices and more; special interest group discussions; a technical Exhibit Hall; premeeting courses and technique workshops; specialty tracks for nonphysician providers; and other learning opportunities. NASS is among a small percentage of CME providers that holds the prestigious Accreditation with Commendation designation from the Accreditation Council for Continuing Medical Education (ACCME). In addition to the Annual Meeting, NASS' Education Program offers top-quality, relevant continuing medical education throughout the year at the Spine Masters Institute and travel destinations throughout the country. The Spine Masters Institute (SMI) is the state-of-the-art training facility housed at the NASS headquarters located just outside of Chicago. SMI features a 12 station bio-skills lab, 100-plus person auditorium, multi-purpose function room and multimedia center that controls the cutting-edge training infrastructure. NASS members are entitled to special, discounted registration fees for all NASS sponsored education programs. The NASS Clinical Care Council promotes high quality spine care and offers numerous clinical resources to spine care providers and their patients such as clinical guidelines, performance measurement information, patient safety information and tools, spine safety alerts and more. 192 NORTH AMERICAN SPINE SOCIETY NASS' Research Grant and Fellowship program supports the best of spine research applications and has provided nearly $2 million in research funding to date. The NASS Socioeconomic Affairs program promotes sound health care policies for fair and reasonable payment systems that ensure patient access to quality spine care. NASS works collaboratively with medical specialty societies, federal agencies and insurers to develop coding, coverage and reimbursement policy for spine care. NASS also monitors the practice environment to be a source of information to members and others about the state of spine care practice. NASS provides numerous diverse practice management resources. To pursue its advocacy agenda, NASS established the National Association of Spine Specialists, a trade association that unites spine care providers, patients and industry in the fight for sound health policy. Through awareness campaigns, legislative updates, action alerts, events and partnerships with other medical specialties, NASS Advocacy helps members understand the issues shaping health care policy and provides opportunities for members to advocate for change at the state and federal levels. NASS' Public Education program implements an annual national Spine Health media campaign, develops patient education materials and promotes ongoing public relations efforts. NASS' Publishing program produces several periodicals, publications and online resources. The Spine Journal (TSJ) is the official scientific, peerreviewed journal of NASS. Now in its seventh year of publication, TSJ has rapidly become a leader in the field and was recognized for its unique contribution to the field by acceptance into Index Medicus/ MEDLINE in its second year of publication. For more information on TSJ, please visit the manuscript tracking Web site at www.ees.elsevier.com/spinee. NASS created the Outstanding Paper Awards in 1989 to recognize excellence in unpublished research in spine care. Submissions are accepted from any spine care professional; NASS membership is not required.
