Based on the previously established 3-dimensional model, this study uses the finite element analytical method to observe the effects of superior articular process resection and intervertebral discectomy on the stress of the surgical segment under different motion states. ⋯ Select resection of the superior articular process base as much as possible to expose the target of the disc. And minimize annulus damage and disc removal.

Inter body spacers have been widely used in patients undergoing spinal fusion surgery; however, it is not clear whether one implant shows superior clinical outcomes compared with the other. This systematic review and meta-analysis comprehensively evaluated the radiologic outcomes and patient-reported outcomes of structural allograft versus polyetheretherketone (PEEK) implants in patients undergoing spinal fusion surgery. ⋯ Our systematic review and meta-analysis show that structural allograft has a higher fusion rate compared with PEEK implants in patients undergoing spinal fusion surgery. In addition, structural allograft has a lower pseudarthrosis rate and reoperation rate.

Patient Selection Criteria in Ambulatory Spine Surgery: Single Canadian Provincial Experience.
Ambulatory spinal surgery is a care delivery model meant to improve patient outcomes and reduce in-hospital length of stay (LOS). We reviewed the experience of implementing an outpatient spine surgery program in Manitoba, Canada and highlight elements that can be used to reduce LOS and re-presentation to hospital. ⋯ We identified several patient and surgical criteria that correlate with prolonged length of stays following planned ambulatory spine surgery. Our work provides some empiric evidence to help guide surgeons on which patients and approaches are ideal for ambulatory surgery.

Over the past century, neuroendoscopy developed into a mainstay of neurosurgical practice, allowing for minimally invasive approaches to the ventricles, skull base, and spine. Its development, however, is far from over. ⋯ New optics allow for significantly improved image quality; yet open craniotomy often allows for 3-dimensional visualization and bimanual dissection and is part of everyday neurosurgical training. Finally, the utilization of neuroendoscopy remains limited, presenting ongoing challenges for neurosurgical teaching and achievement of technical mastery.

Complications of Cervical Endoscopic Spinal Surgery : A Systematic Review and Narrative Analysis.
There are no systematic evidence-based medical data on the complications of endoscopic cervical spinal surgery. This narrative analysis compiled data from various studies that examined endoscopic complications, such as cervical disc herniation and foraminal stenosis. This study aimed to investigate the efficacy and safety of endoscopic surgery in cervical radiculopathy. ⋯ Complications of full endoscopic cervical spinal surgery differ significantly depending on the anterior and posterior approaches. In the anterior approach, swallowing difficulty, recurrent disc, hematoma, and dysphonia are the common complications. In contrast, transient dysesthesia, dural tears, upper limb motor deficits, and persistent arm pain are commonly reported with the posterior approach.
