Frailty is a measure of decreased physiologic reserve and has been associated with increased morbidity and mortality in a variety of surgical disciplines. No data exist regarding the relationship of frailty with adverse outcomes in craniotomy for chronic subdural evacuation. We assessed the relationship between frailty and the incidence of major postoperative complication, discharge destination other than home, 30-day readmission, and 30-day mortality after craniotomy for atraumatic subdural evacuation. ⋯ Preoperative frailty, as determined by mFI-5, is associated with increased odds of major postoperative complication, discharge to destination other than home, and 30-day mortality after craniotomy for chronic subdural hematoma.

The coronavirus disease 2019 pandemic poses major risks to health care workers in neurocritical care. Recommendations are in place to limit medical personnel attending to the neurosurgical patient as a protective measure and to conserve personal protective equipment. However, the complexity of the neurosurgical patient proves to be a challenge and an opportunity for innovation. The goal of our study was to determine if telemedicine delivered through smart glasses was feasible and effective in an alternative method of conducting ward round on neurocritical care patients during the pandemic. ⋯ Virtual ward rounds using telemedicine via smart glasses on neurosurgical patients in critical care were feasible, effective, and widely accepted as an alternative to physical ward rounds during the coronavirus disease 2019 pandemic.

Radiographic nonunion rates in the literature for posterolateral lumbar fusions with pedicle screws (PLFs) range from 8.1% to 43.3% but may not represent nonunion rates. A few small studies have reported reoperations for symptomatic nonunions (operative nonunions) to range from 3.2% to 13.9%. The objective of this study is to determine operative nonunion rates for 1-level, 2-level, 3-level, and ≥4-level PLFs and to determine the risks for these nonunions. ⋯ Our study reports results from one of the largest cohort of patients for the first time with single-level and multilevel instrumented PLFs and found a 2-year operative nonunion rate of 1.08% with increased risk of nonunion for constructs that included L5-S1 and ≥3-level fusions. Operative nonunion combines clinical and radiographic data and provides an alternative measure of fusion rates.

Observational Study
Effect of Disc Height and Degree of Distraction on Heterotopic Ossification After Cervical Disc Replacement.
Heterotopic ossification (HO) is a potential and severe complication of cervical disc replacement (CDR). However, the underlying mechanism of CDR and its association with preoperative disc height loss (DHL) and postoperative degree of distraction remain unclear. We hypothesized that DHL and postoperative degree of distraction could predict HO after CDR. ⋯ DHL and ADD are associated with the development of HO after CDR. The cutoff value of DHL may narrow the criteria for CDR with the aim of reducing HO formation. The combined parameter may help surgeons to select the most suitable implant height to reduce the prevalence of HO.

Case Reports
Spontaneous Spinal Subarachnoid Hemorrhage from a Ruptured Radiculopial Artery Aneurysm.
Spontaneous spinal subarachnoid hemorrhage is an uncommon entity and is even rarer when secondary to intraspinal ruptured aneurysm. The clinical presentation of these cases usually includes back pain and headache; however, we report a unique case in which the patient became acutely paraplegic. ⋯ This unique clinical case highlights a rare cause of spontaneous acute paralysis and further demonstrates the safety of obliterating an intraspinal aneurysm via operative resection.
