There are numerous innovative and promising approaches aimed at slowing, reversing, or healing degenerative disc disease. However, multiple treatment-specific impediments slow progress toward realizing the benefits of these therapies. First, the exact pathophysiology underlying degenerative disc disease remains complicated and challenging to study. ⋯ Biological treatments are subject to the complex biomechanical environment in which native discs degenerate. The regulatory approval environment for these therapeutics will likely involve a high degree of scrutiny. Finally, patient selection and assessment of outcomes are a particular challenge in this clinical setting.

The scalpel sign is a radiological finding observed on sagittal magnetic resonance imaging and computed tomography myelography corresponding to an indentation in the dorsal aspect of the spinal cord resembling a surgical scalpel blade. It is said to be a pathognomonic imaging discovery linked to dorsal arachnoid webs. However, other spine-related conditions may mimic dorsal arachnoid webs on magnetic resonance imaging, such as spinal arachnoid cysts or ventral spinal cord herniation, leading to misdiagnosis. ⋯ Isolated radiological presentation of the scalpel sign is not sufficient to distinguish between dorsal arachnoid webs, arachnoid cysts, and ventral herniation of the spine. However, awareness of its importance is relevant for accurate curative surgical planning.

Hydrocephalus is a common complication of aneurysmal subarachnoid hemorrhage (aSAH) that often requires acute placement of an external ventricular drain (EVD). The current systems available for determining which patients will require long-term cerebrospinal fluid diversion remain subjective. We investigated the ventricular volume change (ΔVV) after EVD clamping as an objective predictor of shunt dependence in patients with aSAH. ⋯ The ΔVV volume between head CT scans taken before and after EVD clamping was predictive of early and delayed shunt dependence.

Comparative Study
Single Level Minimally Invasive Transforaminal Lumbar Interbody Fusion vs Anterior Lumbar Interbody Fusion with Posterior Instrumentation at L5/S1.
To compare outcomes between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and anterior lumbar interbody fusion (ALIF) at L5/S1. ⋯ Patients undergoing ALIF showed significantly improved rates of MCID achievement for disability, physical function, and back pain during the early postoperative period. However, the overall MCID achievement rate for leg pain was higher for the MIS-TLIF cohort.

"Hybrid workshops during COVID-19 pandemic" - Dawn of a new era in neurosurgical learning platforms.
During the COVID-19 pandemic, disruption of surgical hands-on training has hampered the skills acquisition by budding neurosurgeons. Online and virtual classrooms have not been able to substitute the hands-on experience and learning via direct interaction with senior colleagues. To overcome these challenges, we organized a hybrid workshop where simulation-based learning modules, and direct and virtual interaction with surgeons during live surgeries or didactic lectures were utilized to help delegates in understanding the nuances of neurosurgery. ⋯ In this era of the COVID-19 pandemic, "hybrid" microneurosurgery workshops offer unique opportunities to enhance surgical skills acquisition by hands-on simulation-based learning and observing live surgical demonstrations, apart from 2-way interactions with experts under one roof. This may be a stepping stone for what lies ahead in the future of neurosurgical training.
