Review Case Reports
Neurological Complications of Preoperative Embolization of Spinal Metastasis: A Systemic Review of the Literature Identifying Distinct Mechanisms of Injury.
Preoperative embolization of spinal metastases may improve outcomes of resection by reducing surgical blood loss and operative time. Neurologic complications are rarely reported and the mechanisms leading to injury are poorly described. ⋯ Neurologic injury is a risk of preoperative embolization of spinal metastasis from either compromise of spinal cord vascular supply or cranial stroke from reflux of embolic particles. Postprocedural tumor swelling rarely leads to clinical deficit. Awareness of these complications and the presumed mechanisms of injury may aid clinicians in implementing interventions and in counseling patients before treatment.

New York City is the epicenter of the novel coronavirus disease 2019 (COVID-19) pandemic in the United States. Traumatic brain injury accounts for a significant proportion of admissions to our trauma center. We sought to characterize the effect of the pandemic on neurotraumas, given the cancellation of nonessential activities during the crisis. ⋯ A decrease in the frequency of neurotraumas was observed during the COVID-19 crisis concomitant with the increase in COVID-19 patients in the city. This trend began after the cancellation of nonessential activities and implementation of social distancing recommendations.

C-arm-Free Circumferential Minimally Invasive Surgery for Adult Spinal Deformity: A technical note.
Circumferential minimally invasive surgery (cMIS), as a technique for reducing the complications of adult spinal deformity surgery, is receiving considerable attention. Conventional cMIS is performed using intraoperative fluoroscopy. In this work, we describe a new cMIS technique without using C-arm fluoroscopy for correcting adult spinal deformities. ⋯ C-arm-free cMIS for adult spinal deformity is a useful technique that reduces percutaneous screw and cage misplacement. With this new technique, the surgeons and the operation room staff can avoid the risk of an adverse event of intraoperative radiation.

Comparative Study
Does Fusion Affect the Anterior Bone Loss of Adjacent Cervical Disc Arthroplasty in Contiguous 2-Level Hybrid Surgery?
To investigate whether anterior bone loss (ABL) in cervical discarthroplasty (CDA) in 2-level hybrid surgery (HS) is affected by adjacent fusion in vivo compared with 1-level CDA alone. ⋯ ABL was common in both CDA and HS. Although HS had a lower incidence rate and degree than did CDA, the fusion location in HS did not affect the ABL of adjacent CDA.

This case series describes the use of the Medtronic Micro Vascular Plug (MVP) system in the treatment of acute massive orofacial hemorrhages in patients with cancer and trauma, resulting in successful hemostasis in these emergent cases. ⋯ These cases demonstrate that the MVP as an embolic device is a valuable transarterial embolic treatment option in cases of acute orofacial bleeding where rapid, effective hemostasis is required.
