Cervical discectomy is commonly required for spinal cord and nerve compression disorders. Currently, anterior cervical discectomy and fusion is the standard procedure for the treatment of cervical disc herniations and cervical degenerative disorders, whereas endoscopic cervical discectomy is considered an important alternative. Despite the advancement in surgical technology, endoscopically removing hard pathological tissues remains challenging. Inspired by lumbar epidurogram-guided decompression, we have developed an epidurogram-guided endoscopic cervical decompression technique. The technique uses contrast dye through cervical discography to generate an epidurogram. Under fluoroscopic view, the spinal cord is posterior to the contrast line. The endoscopic instruments can safely reach the epidural space, if it's necessary, as long as they stay anterior to the contrast line. We have used this technique to treat both soft and hard cervical disc herniations, and we have found it makes the surgical procedures safer when more aggressive decompression is required.

Objective: This study presents a novel odontoid parameter, the odontoid incidence (OI), to examine the correlation between OI on preoperative cervical sagittal radiographs and 2-year clinical outcomes following short-segment anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylotic myelopathy (CSM).
Methods: A retrospective analysis of the clinical data of 87 patients with CSM who underwent ACDF surgery from January 2018 to December 2023 was conducted. The patients were categorized into a larger OI group (44 patients, OI > 12.

Background: Early esophageal fistula formation following anterior cervical spine surgery presents a formidable clinical challenge, necessitating astute rehabilitative nursing management. Such fistulas, if not promptly and effectively managed, can precipitate grave complications including mediastinitis, sepsis, respiratory failure, and, in severe instances, mortality. This underscores the critical need for immediate, comprehensive nursing interventions designed to mitigate these risks and enhance patient outcomes.

The urgent etiological diagnosis represents the main management objective of cervical spondylodiscitis (CSD) to start as soon as possible antibiotic treatment to prevent neurological deterioration. The present study aimed to evaluate a multicenter experience implementing a minimally invasive surgical approach (MISA) to manage CSD such pathology vs the most complex and aggressive surgical strategies currently used.This retrospective multicenter study used a database of 70 patients from five European neurosurgical centers.

Introduction: Spine surgery is a common source of narcotic prescriptions and carries potential for long-term opioid dependence. As prescription opioids play a role in nearly 25 % of all opioid overdose deaths in the United States, mitigating risk for prolonged postoperative opioid utilization is crucial for spine surgeons.
Purpose: The aim of this study was to employ six ML algorithms to identify clinical variables predictive of increased opioid utilization across spinal surgeries, including anterior cervical discectomy and fusion (ACDF), posterior thoracolumbar fusion (PTLF), and lumbar laminectomy.
