Objective To replace educational opportunities lost during the coronavirus disease 2019 (COVID-19) pandemic, the Department of Neurosurgery at Lenox Hill Hospital produced an open-access webinar series (“BRAINterns”) that covered a broad range of health care topics with a focus on neurosurgery. Methods This 8-week webinar series ran from July 1 to August 28, 2020. An optional exit survey was distributed to participants. Data were analyzed to characterize and better understand trends among a global cohort of participants. Results A total of 16,484 people registered for BRAINterns, and 6675 took the survey (40.5% response rate). Responders represented 87 countries, of which the majority were from the United States and Canada (90.48%, n = 6039). Responders were primarily female (82.9%, n = 5521). Racial and ethnic representation was majority Asian (42%, n = 2798), followed by White (22.7%, n = 1514), Hispanic/Latino (16.2%, n = 1080), and Black and African American (7.7%, n = 516). Participants reported hearing about BRAINterns through various social media platforms (72.18%, n = 4818)—the most popular was TikTok (33.4%, n = 2232). Overall, 93.4% of participants reported that the course was a good use of their time during the pandemic, and 86.7% reported that the course helped replace lost opportunities. Conclusions These data demonstrate that webinar-based education is an effective method of expanding access to careers in medicine and in particular, neurosurgery, to traditionally underrepresented populations. Social media can be a powerful tool to combat barriers to early exposure and vastly improve diversity within the field.

Background The coronavirus disease 2019 (COVID-19) pandemic has infected more than 13 million people on a global scale and claimed more than half million deaths across 213 countries and territories. While the focus is currently on recovery from the pandemic, the disease has significantly changed the way we practice medicine and neurosurgery in New York City and the United States. Apart from the emergency cases, several health systems across the country have similarly started to perform elective surgeries. Although COVID-19 screening and testing guidelines have been proposed and adopted by many hospitals, these may not adequately protect the operating room personnel who are in proximity to the patient for prolonged periods. There are concerning reports of especially high transmission rates of COVID-19 in transmucosal head and neck procedures conducted by otolaryngologists and neurosurgeons, despite attempts at wearing what constitutes appropriate personal protective equipment. Methods Here, we describe a simple technique of additional draping that can be used for all cranial, endonasal, spinal, and neurointerventional cases to limit the transmission of coronavirus. Results The proposed technique offers a simple, commonly available, cost-effective alternative that avoids the use of additional retractor systems. Moreover, this technique can be used in all neurosurgical procedures. Conclusions With the rising concerns regarding airborne spread of the virus, we expect that these precautions will prove highly useful as we enter the recovery phase of this pandemic and hospitals attempt to prevent a return to widespread infection. In addition, its availability and cost effectiveness make this technique especially attractive to practical use in centers with limited resources.

Background The coronavirus (COVID-19) pandemic effectively ended all major spine educational conferences in the first half of 2020. In response, the authors formed a “virtual” case-based conference series directed at delivering spine education to healthcare providers around the world. We herein share the technical logistics, early participant feedback, and future direction of this initiative. Methods The Virtual Global Spine Conference (VGSC) was created in April 2020 by a multi-institutional team of spinal neurosurgeons and a neuroradiologist. Biweekly virtual meetings were established wherein invited national and international spine care providers would deliver case-based presentations on spine and spine surgery-related conditions via teleconferencing. Promotion was coordinated through social media platforms such as Twitter. Results VGSC recruited over 1000 surgeons, trainees and other specialists, with 50-100 new registrants per week thereafter. An early survey to the participants, with 168 responders, indicated that 92% viewed the content as highly valuable to their practice and 94% would continue participating post-COVID. Participants from the United States (29%), Middle East (16%), and Europe (12%) comprised the majority of the audience. Approximately 52% were neurosurgeons, 18% orthopaedic surgeons, and 6% neuroradiologists. A majority of participants were physicians (55%) and residents/fellows (21%). Conclusion The early success of the VGSC reflects a strong interest in spine education despite the COVID pandemic and social distancing guidelines. There is widespread opinion, backed by our own survey results, that many clinicians and trainees wish to see “virtual” education continue post-COVID., Highlights • The coronavirus pandemic had a detrimental impact on spine education and societal conferences • Teleconferencing platforms have been increasingly used to replace in-person events • Virtual Global Spine Conference was created to deliver spine education during the pandemic • Early survey results demonstrate excellent participant enthusiasm for continued virtual education post-pandemic Abstract

Background The Coronavirus disease 2019 (COVID-19) outbreak has left a lasting mark on medicine globally. Methods Here we outline the steps that the Lenox Hill Hospital/Northwell Health Neurosurgery Department—located within the epicenter of the pandemic in New York City—is currently taking to recover our neurosurgical efforts in the age of COVID-19. Results We outline measurable milestones to identify the transition to the recovery period and hope these recommendations may serve as a framework for an effective path forward. Conclusions We believe that recovery following the COVID-19 pandemic offers unique opportunities to disrupt and rebuild the historical patient and office experience as we evolve with modern medicine in a post–COVID-19 world.

Background Acute traumatic isolated transverse process fractures (ITPFs) are increasingly identified in trauma patients owing to the increased use of routine computed tomography imaging. Despite repeated demonstrations that these fractures are treated only symptomatically, patterns of consultation with a spine service have not changed. We aim to provide information on long-term outcomes following conservative treatment to help clarify the role of the spine service in the treatment of ITPFs. Methods A retrospective chart review of 306 patients presenting with ITPFs was conducted to identify both short-term and long-term patient outcomes. A subsection of patients was identified with no other traumatic injuries besides isolated ITPFs (iITPFs). Results No patient required surgical intervention for an ITPF, and 97.7% of all patients and 100% of the patients with iITPFs did not require bracing. At last follow-up, all patients were neurologically intact, 97.8% were fully ambulatory, and 87.9% had no ITPF-related back pain. When only patients with 6 or more months of follow-up were considered, all patients were fully ambulatory, and only 1.1% of all patients and none of the patients with iITPFs had persistent back pain. Conclusions ITPFs can be treated conservatively without concern for long-term outcome sequelae such as pain, neurologic deficits, or ambulatory difficulties. Consequently, a spine service consult is not required for patients with ITPFs.

Background Double, noncontiguous, 3-column spinal injuries are a rare phenomenon most often caused by high-energy trauma. The resulting multilevel, fracture-dislocation injuries represent 2 separate 3-column lesions and produce a floating spine segment between the 2 fracture dislocation sites. Only a few cases of these rare, posttraumatic injuries have been reported previously; however, all of these included a combination of injuries in the cervical, thoracic, lumbar, and/or sacral spine. Case Description We present the first report of a case of double-level spinal injury isolated to the thoracic spine, with an intermediate floating spinal segment in a 48-year-old man after a 30-foot fall. In our case, the standard 3 above and 2 below pedicle instrumentation was not sufficient to stabilize the thoracic spine. Conclusions We consider the evaluation and surgical management of these fractures and discuss how a standard “3 above-2 below” approach may not be sufficient to stabilize these unstable injuries. In the case of severe, noncontiguous double chance fractures of the spine, we recommend a more extensive anteroposterior approach to reduce the risk of hardware failure and worsening spinal deformity.

Teratomas of the spinal cord constitute 0.1% of all spinal tumors, and these lesions are extremely rare in adults. The authors describe a rare case of intradural intramedullary teratoma of the conus medullaris and perform review of literature of intramedullary teratomas seen in the thoracolumbar region.A 48-year-old man presented with fasciculations in the bilateral upper and lower extremities. Radiologic findings revealed an L2-L3 level intradural, nonenhancing, extramedullary cystic mass measuring 15 × 13 mm with a 6-mm enhancing nodule at the level of the conus medullaris. The patient was followed up for 1 year, during which time enlargement of the lesion with new areas of patchy contrast enhancement were observed. L1-L2 decompressive laminectomies were performed, and gross total resection of the lesion was achieved. Histopathologic examination confirmed the diagnosis of benign mature cystic teratoma. A literature review revealed no incidence difference in intramedullary teratomas between males and females (P0.05). The mean age at the time of diagnosis was 36.4 ± 12.3 years for men and 41.3 ± 11.6 for women (P0.05). The mean symptom duration before treatment was 64.6 ± 79.4 months for females and 20.7 ± 13.8 months for men (P0.05). Complete resection was achieved in 48.1% of the cases.Teratomas should be taken into consideration in the differential diagnosis of intramedullary lesions when the imaging reveals variable signal intensity because of tissue heterogeneity. A partial resection is a viable treatment option when the lesion is attached to vital structures because of the low recurrence rates reported in the literature.

Anterior cervical discectomy and fusion (ACDF) is one of the most common spinal procedures performed. A direct comparison of the fusion and complication rates between recombinant human bone morphogenetic protein-2 (rhBMP2) and beta-tricalcium phosphate (bTCP) has not been reported.A retrospective study of 191 consecutive patients who underwent ACDF with polyetheretherketone plastic fusion spacers during a 2-year period with either rhBMP2 (n = 84, 46%) or bTCP (n = 107, 56%) was performed. Patients underwent 1- (35%), 2- (41%), 3- (20%), and 4- (4%) level operations. The primary outcome measure was mature arthrodesis, with secondary measures including clinical outcomes and complication occurrence. Fusion was graded on plain lateral radiographs, with median length of follow-up of 12 months.Rates of cervical fusion were significantly greater for patients treated with rhBMP2 than bTCP at both 6 months (70% vs. 26%, P = 0.000) and 12 months (99% vs. 85%, P = 0.000). Postoperative dysphagia was reported in 35 patients (18%), with no difference in dysphagia incidence between rhBMP2 and bTCP (20% vs. 17%, P = 0.5); however, dysphagia was more severe in the rhBMP2 group, with greater rates of readmission and steroid use (both P0.05). A multivariable sensitivity analyses to control for patient characteristics and number of spinal fusion levels showed no differences in dysphagia rate between rhBMP2 and bTCP.In our cohort, the rate of mature arthrodesis after ACDF was greater with rhBMP2 compared with bTCP with no increased incidence of postoperative dysphagia; however, dysphagia severity was greater in the rhBMP2 cohort.
