Spinal cord trauma leads to the destruction of the highly organized cytoarchitecture that carries information along the axis of the spinal column. Currently, there are no clinically accepted strategies that can help regenerate severed axons after spinal cord injury (SCI). Hydrogels are soft biomaterials with high water content that are widely used as scaffolds to interface with the central nervous system (CNS).

Background: Full endoscopic spine surgery (FESS) champions a rapid recovery and a low rate of overall complications. However, its efficacy in geriatric patients that might yield additional benefits from minimized invasiveness remains underexplored.

Methods: A multi-institutional prospective cohort study was conducted involving patients undergoing elective lumbar FESS.

Background And Context: Unplanned readmission within 30 days following elective spine surgery is a key indicator of quality of care, as readmissions often signal early complications or poor recovery. The Hospital Readmission Reduction Program (HRRP) and the Centers for Medicare and Medicaid Services (CMS) utilizes this metric to assess hospital and surgeon performance.

Purpose: Here we aim to delineate quality of care metrics for full-endoscopic spine surgery (FESS) compared to traditional spine surgery.

Background Context: Endoscopic spine decompression surgery (ESDS) offers numerous benefits, including reduced tissue damage, smaller incisions, shorter recovery times, and a lower risk of complications. However, its adoption among spine surgeons in the United States has been slow. The reluctance to adopt ESDS can be attributed to factors such as the learning curve, cost of equipment and training, and limited access to necessary resources.

Due to demographic changes, a growing number of elderly patients with comorbidities will require spine surgery in the next decades. However, age and multimorbidity have been associated with considerably worse postoperative outcomes, and is often associated with surgical invasiveness. Full-endoscopic spine-surgery (FESS), as a cornerstone of contemporary minimally invasive surgery, has the potential to mitigate some of these disparities.

Article Synopsis
  • Traumatic spinal cord injury (tSCI) leads to quick loss of neurological function, making recovery prediction challenging.
  • The study used contrast-enhanced ultrasound to assess intraspinal blood flow disruption in a rodent model, finding that this disruption was linked to injury severity and locomotor function after 8 weeks.
  • In 27 human cases with varying tSCI severity, results confirmed correlations between ultrasound metrics and both injury severity and functional recovery after 6 months, suggesting potential for these ultrasound metrics in prognostic assessments, although further studies are needed.

Article Synopsis
  • Degenerative spondylolisthesis is a common cause of chronic back pain in adults, and while the standard treatment is open decompression with or without fusion, there is growing interest in the effectiveness of full endoscopic spine surgery as an alternative.
  • A study involving 73 patients with low-grade degenerative spondylolisthesis revealed that after undergoing lumbar endoscopic unilateral laminectomy, 70 patients experienced significant improvement in symptoms and pain levels at various follow-up periods (3, 9, and 12 months).
  • The results indicate that this endoscopic approach is a safe option for treating patients with severe stenosis due to low-grade degenerative spondylolisthesis, suggesting the

Background And Objectives: Emergency department (ED) utilization and readmission rates after spine surgery are common quality of care measures. Limited data exist on the evaluation of quality indicators after full-endoscopic spine surgery (FESS). The objective of this study was to detect rates, causes, and risk factors for unplanned postoperative clinic utilization after FESS.

Purpose: Although comprehensive and widespread guidelines on how to conduct systematic reviews of outcome measurement instruments (OMIs) exist, for example from the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) initiative, key information is often missing in published reports. This article describes the development of an extension of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guideline: PRISMA-COSMIN for OMIs 2024.

Methods: The development process followed the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) guidelines and included a literature search, expert consultations, a Delphi study, a hybrid workgroup meeting, pilot testing, and an end-of-project meeting, with integrated patient/public involvement.

Background And Objectives: Full-endoscopic sacroiliac joint denervation (FE-SJD) is a novel technique for the management of pain secondary to sacroiliac joint dysfunction. The aim of this study was to assess the long-term efficacy, safety, clinical outcomes, and outcome predictors of uniportal full-endoscopic sacroiliac joint denervation.

Methods: From 2019 to 2021, a total of 47 consecutive patients with pain secondary to sacroiliac joint dysfunction underwent uniportal FE-SJD through posterior approach by a single fellowship-trained spine surgeon.

Introduction: Patient-centred care is more than just an aspiration, it represents a fundamental shift in the way healthcare must be delivered. Patient-centred emergency care is important for improving the patient and clinician experience and is essential for optimizing health outcomes. Creating a patient-centred emergency department emphasizes the importance of the patient's experience, preferences, and values.

Background And Objectives: Surgical treatment for symptomatic thoracic disc herniations (TDH) involves invasive open surgical approaches with relatively high complication rates and prolonged hospital stays. Although advantages of full endoscopic spine surgery (FESS) are well-established in lumbar disc herniations, data are limited for the endoscopic treatment of TDH despite potential benefits regarding surgical invasiveness. The aim of this study was to provide a comprehensive evaluation of potential benefits of FESS for the treatment of TDH.

Objectives: This paper describes the evolution and impact of Patient Research Partners (PRPs) in shaping research within OMERACT and provides a framework to enhance their engagement. This session explored one component of a validated framework to evaluate meaningful patient engagement. It provides insights, identifies opportunities for improvement, and recommends using the Patient Engagement in Research (PEIR) Framework, PEIR Plan Guide (workbook), and PEIRS-22 (scale) to guide and measure PRPs' engagement.

The patient is a 22-year-old male with a history of C1 avulsion fracture causing vertebral artery compression with pseudoaneurysm and symptomatic stroke. Cerebral angiography demonstrated dynamic compression of the V3 segment of the vertebral artery due to a chronic C1 avulsion fracture. The authors utilized a full endoscopic approach with intraoperative angiography for proximal control and Doppler ultrasound to confirm adequate decompression.
