The Lumbar Spine Research Society at 10 years: This meeting in the spring of 2017 represents the 10th anniversary of the founding of the Lumbar Spine Research Society. We have certainly come a long way in ten years. The original meeting was organized by invitation only, and was attended by 55 spinal surgeons. 33 podium presentations were given that day, but the majority of the time was spent discussing the organization and goals of a new spinal society. Those goals were to develop a society dedicated to the scientific presentation and discussion of topics concerning lumbar spinal surgery. In addition, we hoped to host a meeting that was independent of industry funding and financially free standing. Our hope was to provide an efficient and concise meeting place for the open exchange of scientifically valid lumbar spine research. Over the past ten years, we have seen a steady and substantial growth in the society. The original meeting had 41 submitted abstracts for presentation. For 2017, there were 228 scientific abstracts submitted. 42 of these will be presented from the podium, 30 as a brief podium presentation, and 40 as poster presentations. Attendance has grown steadily from the original 55 members to 161 attendees at last year’s meeting. In 2013, we began our first instructional course and this has had steady growth over the past four years. Also in 2013, we awarded our first research grant recipient. We have now been able to fund a research grant in each of the past four years in order to provide pilot funding for scientific research. More importantly our membership has increased steadily. Over the past five years alone, membership has increased from 77 to 147. Having a dedicated group of members in attendance each year is what has led to our meeting success. A small meeting, concise, with scientifically sound presentations and ample time for open discussion, is what has made this one of the most exciting and thought provoking meetings of the year. Our new members include many recently graduated Neurosurgeons and Orthopedic Surgeons who have completed Spine Fellowships. This has helped generate the presentation and discussion of cutting edge topics including surgical approach, techniques, and technology. I welcome you to the 10th annual LSRS meeting. I certainly hope that you will enjoy the meeting and continue to spread the word that valid scientific information can be disseminated free of industrial influence or distraction. If not currently a member, please consider joining us. We would love to have you. Thomas A. Zdeblick, M.D. Founding Member of LSRS

Dear Colleagues: A core principle of our mission is to promote research in lumbar spine surgery. As a young organization, our focus was growth and stability. Despite numerous challenges, including our vision to remain as free as possible from commercial bias and industry involvement, our Society is thriving. For the first decade of our organization, the members of the LSRS Board of Directors have personally provided the majority of funding towards this goal. For the long-term success of the LSRS Research Grant program, we will need members and attendees to consider donating generously to the Research Fund. The LSRS Board feels that we are positioned to impact lumbar spine research in a direct and meaningful way. 100% of the money raised has funded research projects endorsed by the Research Committee and the Executive Committee. The current goal is to grant $20,000 per year to the best submission. This initial support has functioned as seed money for eventual NIH submissions. All projects involve active members of the Society. Please consider making a generous tax-deductible credit card donation to the Research Fund via our website: LSRS.org Alternatively, you may make a donation of appreciated stock which has the additional benefit of being exempt from capital gains tax. Please contact us for details regarding this option. Please feel free to contact me with any questions. Thank you for your contribution to the Research Fund. Sincerely,
Paul A. Anderson, MD President, LSRS

Paper 01 Efficacy and Safety of High-dose Tranexamic Acid Protocol in Adult Spinal Deformity – Analysis of 100 Consecutive Cases James Lin, MD, MS1, Jamal Shillingford, MD2; Joseph Laratta, MD2, Lee Tan, MD1, Charla Fischer, MD3, Ronald Lehman, MD4, Lawrence Lenke, MD2 1 Columbia University Medical Center, New York, NY, 2, New York, NY, 3Columbia University Department of Orthopaedic Surgery, New York City, New York, 4, New York, NY Background/Introduction: Adult spinal deformity (ASD) surgery is a massive undertaking that may involve a significant amount of blood loss, especially when various osteotomy techniques are utilized. Antifibrinolytic agents such as tranexamic acid (TXA) have been used in an attempt to reduce intraoperative blood loss. However, there is no universally accepted dosing protocol for TXA in spine surgery. Moreover, there are very few reports in the literature regarding high-dose TXA use in ASD, possibly due to concerns for thromboembolic or seizure risks. This study aims to investigate the safety profile and efficacy of using a high-dose (50mg/kg loading, 5mg/kg/hr infusion) TXA protocol during ASD surgery. Materials/Methods: Consecutive patients undergoing spinal deformity correction over a 14-month period (September 1st 2015 – November 1st 2016) at a single institution were identified. Inclusion criteria were adults (age >= 18 years) who underwent posterior spinal fusion surgery of at least 5 levels. Our standard TXA protocol is 50 mg/kg intravenous loading dose followed by a 5 mg/kg/hr infusion until skin closure. Patient demographics, estimated blood time (EBL), post operative blood transfusion, and other procedure specific information were recorded and analyzed. Results: A total of 100 adult patients were included in the study. Operative procedures were performed by a single surgeon. The mean age was 46.5 years, and 71% of patients were female. Average BMI was 24.7. The average fusion length was 14 levels. 46/100 patients had a primary surgical procedure while the rest were revisions. 61/100 of patients had pelvic fixation. Posterior column osteotomies were performed on 80/100 patients; pedicle subtraction osteotomy (PSO) was performed in 8 patients; and vertebral column resections (VCRs) were performed in 15 patients. Mean intraoperative blood loss among all patients was 1296cc. There was one PE was treated with a heparin drip, and two DVTs which developed in rehab which were treated with oral anticoagulation. There were no MIs, seizures, strokes, or renal complications. Discussion/Conclusion: This study demonstrates that high dose TXA is effective and safe to use in well-selected ASD patients and lays the foundation for further studies on this important topic.

Paper 02 Comparison of Bleeding vs Clotting Complications after Lumbar Spine Surgery Haroutioun Boyajian, MD1, Olumuyiwa Idowu, BA2, William Mosenthal, MD1, Lewis Shi, MD1, Michael Lee, M.D.3 1 , Chicago, IL, 2, Chicago, Illinois, 3University of Chicago Medical Center, Chicago, IL Background/Introduction: Unlike almost all other inpatient surgery, chemical anticoagulation after spine surgery is frequently withheld due to fear of bleeding complications. Unlike most other surgeries, bleeding complications after spine surgery can result in neurological injury. The purpose of this study was to compare the incidence of bleeding and clotting complications in patients who have undergone spinal surgery without postoperative anti-coagulation, using a large national database. Materials/Methods: A retrospective review of the Truven Health Marketscan® Research Databases was conducted for patients undergoing lumbar spine operations between 2003 and 2014. Patients were divided into 3 groups: anterior lumbar surgery, posterior lumbar fusion, and posterior lumbar laminectomy. The ICD-9-CM diagnosis codes for epidural hematoma, hematoma, seroma, deep vein thrombosis (DVT), and pulmonary embolism (PE) were used to calculate the incidence of these complications within three months of surgery in each group. The rate of operative intervention for the bleeding complications was assessed and compared to the rate of PE. The relative risks of these complications were calculated for surgical approach and fusion vs. decompression. Results: 379,871 patients were included in the study. Overall, 8,609 (2.3%) patients developed bleeding complications (seroma+hematoma+epidural hematoma) while 13,384 (3.5%) developed clotting complications (DVT + PE). 1222 (.32%) patients underwent surgical drainage for their bleeding complication, and 1,216 (0.32%) patients developed PE. While the rates of all bleeding complications were comparable to the rates of all thrombosis complications in all subgroups, the rate of PE was 5-7 fold higher than the rate of bleeding complication requiring operative intervention in all sub groups (p
