    Abstract: The Neurosurgery Research & Education Foundation (NREF), previously known as the Research Foundation of the American Association of Neurological Surgeons (AANS), was established in 1980 to encourage and facilitate innovation through financial support to young neurosurgeons in the process of honing their competencies in neurosciences and neurological surgery. This article provides a historical overview of NREF, its mission, and charitable contributions and the ever-expanding avenues for neurosurgeons, neurosurgical residents and fellows, and medical students to supplement clinical training and to further neurosurgical research advances. METHODS Data were collected from the historical archives of the AANS and NREF website. Available data included tabulated revenue, geographic and institutional records of funding, changes in funding for fellowships and awards, advertising methods, and sources of funding. RESULTS Since 1984, NREF has invested more than $23 million into the future of neurosurgery. To date, NREF has provided more than 500 fellowship opportunities which have funded neurosurgeons’ education and research efforts at all stages of training and practice. CONCLUSIONS NREF is designed to serve as the vehicle through which the neurosurgical community fosters the continued excellence in the care of patients with neurosurgical diseases.

    Abstract: The Neurosurgery Research and Education Foundation (NREF) provides research support for in-training and early career neurosurgeon-scientists. To define the impact of this funding, the authors assessed the success of NREF awardees in obtaining subsequent National Institutes of Health (NIH) funding. METHODS NREF in-training (Research Fellowship [RF] for residents) and early career awards/awardees (Van Wagenen Fellowship [VW] and Young Clinician Investigator [YCI] award for neurosurgery faculty) were analyzed. NIH funding was defined by individual awardees using the NIH Research Portfolio Online Reporting tool (1985–2014). RESULTS Between 1985 and 2014, 207 unique awardees were supported by 218 NREF awards ($9.84 million [M] in funding), including 117 RF ($6.02 M), 32 VW ($1.68 M), and 69 YCI ($2.65 M) awards. Subspecialty funding included neuro-oncology (79 awards; 36% of RF, VW, and YCI awards), functional (53 awards; 24%), vascular (37 awards; 17%), spine (22 awards; 10%), pediatrics (18 awards; 8%), trauma/critical care (5 awards; 2%), and peripheral nerve (4 awards; 2%). These awardees went on to receive $353.90 M in NIH funding that resulted in an overall NREF/NIH funding ratio of 36.0:1 (in dollars). YCI awardees most frequently obtained later NIH funding (65%; $287.27 M), followed by VW (56%; $41.10 M) and RF (31%; $106.59 M) awardees. YCI awardees had the highest NREF/NIH funding ratio (108.6:1), followed by VW (24.4:1) and RF (17.7:1) awardees. Subspecialty awardees who went on to obtain NIH funding included vascular (19 awardees; 51% of vascular NREF awards), neuro-oncology (40 awardees; 51%), pediatrics (9 awardees; 50%), functional (25 awardees; 47%), peripheral nerve (1 awardees; 25%), trauma/critical care (2 awardees; 20%), and spine (2 awardees; 9%) awardees. Subspecialty NREF/NIH funding ratios were 56.2:1 for vascular, 53.0:1 for neuro-oncology, 47.6:1 for pediatrics, 34.1:1 for functional, 22.2:1 for trauma/critical care, 9.5:1 for peripheral nerve, and 0.4:1 for spine. Individuals with 2 NREF awards achieved a higher NREF/NIH funding ratio (83.3:1) compared to those with 1 award (29.1:1). CONCLUSIONS In-training and early career NREF grant awardees are an excellent investment, as a significant portion of these awardees go on to obtain NIH funding. Moreover, there is a potent multiplicative impact of NREF funding converted to NIH funding that is related to award type and subspecialty.

    Abstract: The Neurosurgery Research and Education Foundation (NREF) provides diverse funding opportunities for in-training and early-career neurosurgeon-scientists. The authors analyzed the impact of NREF funding on the subsequent career success of neurosurgeons in obtaining research funding and academic achievements. METHODS The NREF database was queried to identify NREF winners from 2000 to 2015. The award recipients were surveyed to obtain information about their demographic characteristics, academic career, and research funding. Only subsequent research support with an annual funding amount of $50,000 or greater was included. The primary outcome was the NREF impact ratio, defined as the ratio between NREF award research dollars and subsequent grant funding dollars. The secondary outcomes were time to subsequent grant funding as principal investigator (PI), clinical practice settings, and final academic position achieved. RESULTS From 2000 to 2015, 158 neurosurgeons received 164 NREF awards totaling $8.3 million (M), with $1.7 M awarded to 46 Young Clinician Investigators (YCIs), $1.5 M to 18 Van Wagenen Fellows (VWFs), and $5.1 M to 100 resident Research Fellowship Grant (RFG) awardees. Of all awardees, 73% have current academic appointments, and the mean ± SD number of publications and H-index were 71 ± 82 and 20 ± 15, respectively. The overall response rate to our survey was 70%, and these respondents became the cohort for our analysis. In total, respondents cumulatively obtained $776 M in post–NREF award grant funding, with the most common sources of funding including the National Institutes of Health ($327 M) and foundational awards ($306 M). The NREF impact ratios for awardees were $1:$381 for YCI, $1:$113 for VWF, and $1:$41 for resident RFG. Awardees with NREF projects in functional neurosurgery, pediatric neurosurgery, and neuro-oncology had the highest NREF impact ratios of $1:$194, $1:$185, and $1:$162, respectively. Of respondents, 9% became department chairs, 26% became full professors, 82% received at least 1 subsequent research grant, and 66% served as PI on a subsequent research grant after receiving their NREF awards. CONCLUSIONS In-training and early-career neurosurgeons who were awarded NREF funding had significant success in acquiring subsequent grant support, research productivity, and achievements of academic rank. NREF grants provide a tremendous return on investment across various career stages and subspecialities. They also appeared to have a broader impact on trajectory of research and innovation within the field of neurosurgery.

    The effect of posterior polyester tethers on the biomechanics of proximal junctional kyphosis: a finite element analysis
    Journal of Neurosurgery Publishing Group (JNSPG) ; 2017

    Abstract: Proximal junctional kyphosis (PJK) remains problematic following multilevel instrumented spine surgery. Previous biomechanical studies indicate that providing less rigid fixation at the cranial aspect of a long posterior instrumented construct, via transition rods or hooks at the upper instrumented vertebra (UIV), may provide a gradual transition to normal motion and prevent PJK. The purpose of this study was to evaluate the ability of posterior anchored polyethylene tethers to distribute proximal motion segment stiffness in long instrumented spine constructs. METHODS A finite element model of a T7–L5 spine segment was created to evaluate range of motion (ROM), intradiscal pressure, pedicle screw loads, and forces in the posterior ligament complex within and adjacent to the proximal terminus of an instrumented spine construct. Six models were tested: 1) intact spine; 2) bilateral, segmental pedicle screws (PS) at all levels from T-11 through L-5; 3) bilateral pedicle screws from T-12 to L-5 and transverse process hooks (TPH) at T-11 (the UIV); 4) pedicle screws from T-11 to L5 and 1-level tethers from T-10 to T-11 (TE-UIV+1); 5) pedicle screws from T-11 to L-5 and 2-level tethers from T-9 to T-11 (TE-UIV+2); and 6) pedicle screws and 3-level tethers from T-8 to T-11 (TE-UIV+3). RESULTS Proximal-segment range of motion (ROM) for the PS construct increased from 16% at UIV−1 to 91% at UIV. Proximal-segment ROM for the TPH construct increased from 27% at UIV−1 to 92% at UIV. Posterior tether constructs distributed ROM at the UIV and cranial adjacent segments most effectively; ROM for TE-UIV+1 was 14% of the intact model at UIV−1, 76% at UIV, and 98% at UIV+1. ROM for TE-UIV+2 was 10% at UIV−1, 51% at UIV, 69% at UIV+1, and 97% at UIV+2. ROM for TE-UIV+3 was 7% at UIV−1, 33% at UIV, 45% at UIV+1, and 64% at UIV+2. Proximal segment intradiscal pressures, pedicle screw loads, and ligament forces in the posterior ligament complex were progressively reduced with increasing number of posterior tethers used. CONCLUSIONS Finite element analysis of long instrumented spine constructs demonstrated that posterior tethers created a more gradual transition in ROM and adjacent-segment stress from the instrumented to the noninstrumented spine compared with all PS and TPH constructs. Posterior tethers may limit the biomechanical risk factor for PJK; however, further clinical research is needed to evaluate clinical efficacy.

    Type I fractures of the odontoid process: implications for atlanto-occipital instability : Case report
    Journal of Neurosurgery Publishing Group (JNSPG) ; 1990

    Abstract: ✓ Only four cases of Type I odontoid fracture have been previously described in the English literature. Most authors consider this lesion to be stable, although the mechanism(s) of injury has not been clearly elucidated. A case of Type I odontoid fracture in association with atlanto-occipital and atlantoaxial dislocation resulting in death is presented. The normal ligamentous anatomy is reviewed and proposed mechanisms for this injury are discussed. The radiographic features of all reported cases of this type are reviewed. It is proposed that the Type I odontoid fracture is a likely manifestation of atlanto-occipital instability and rarely occurs as an isolated or stable injury.
