The present systematic review and meta-analysis was conducted to compare the safety and efficacy of the two approaches for primary spinal cord tumors (PSCTs) in adult patients (laminoplasty [LP] vs. laminectomy [LE]). LE is one of the most common procedures for PSCTs. Despite advantages of LP, it is not yet widely used in the neurosurgical community worldwide. The efficacy of LP vs. LE remains controversial. Adult patients over 18 years of age with PSCT at the level of the cervical, thoracic, and lumbar spine were included in the study...

BACKGROUND: Anterior approaches to the cervical spine are among the most common exposures by which neurosurgeons and orthopedic surgeons access the prevertebral space and ultimately the cervical disk and vertebral bodies. There is a paucity of literature describing the microanatomic fascial planes of the neck with respect to anterior cervical approaches. OBJECTIVE: To delineate the microanatomic connections of the cervical fascial planes pertinent to anterior cervical exposure...

BACKGROUND: Safe posterior cervical spine surgery requires in-depth understanding of the surgical anatomy and common variations. The cervical pedicle attachment site to the vertebral body (VB) affects the location of exiting nerve roots and warrants preoperative evaluation. The relative site of attachment of the cervical pedicle has not been previously described. OBJECTIVE: To describe the site of the pedicle attachment to the VB in the subaxial cervical spine. METHODS: Cervical spine computed tomography scans without any structural, degenerative, or traumatic pathology as read by a board-certified neuroradiologist during 2021 were reviewed...

While epidural stimulation of the lumbar spinal cord has emerged as a powerful modality for recovery of movement, how it should be targeted to the cervical spinal cord to activate arm and hand muscles is not well-understood, particularly in humans. We sought to map muscle responses to posterior epidural cervical spinal cord stimulation in humans. We hypothesized that lateral stimulation over the dorsal root entry zone would be most effective, and responses would be strongest in the muscles innervated by the stimulated segment...

BACKGROUND: The choice of surgical method for the treatment of multilevel degenerative cervical spine disease is based on the assessment of neurological symptoms and anatomical source of compression. However, such decision-making process remains complex and poorly defined. PURPOSE: To analyze the effectiveness of an algorithmic posterior approach to the surgical treatment of patients with multilevel degenerative disease of the cervical spine based on the preoperative clinical and imaging parameters...

Introduction: Anterior cervical discectomy and fusion (ACDF) is a common procedure to address cervical spine pathology. The most common grafts used are titanium, polyetheretherketone (PEEK), or structural allograft. Comparison of fusion rate is difficult due to non-standardized methods of assessment. We stratified studies by method of fusion assessment and performed a systematic review of fusion rates for titanium, PEEK, and allograft. Research question: Which of the common implants used in ACDF has the highest reported rate of fusion? Materials and methods: An experienced librarian performed a five-database systematic search for published articles between 01/01/1990 and 08/07/2021...

PURPOSE: To compare the Atlas (C1) lateral mass screw placement between screw trajectories of 0° and 15° medial angulation while using the intersection between lateral mass and inferomedial edge of the posterior arch. METHODS: Forty-eight Atlas lateral masses were prepared and divided into 2 groups: Group 1; screws inserted at 3 mm lateral to the reference point with screw trajectory of 0° angulation(N = 24) and Group 2; those inserted with screw trajectory of 15° medial angulation(N = 24)...

OBJECTIVES: In a retrospective study, we sought to compare the clinical efficacy and postoperative magnetic resonance imaging (MRI) scans of minimally invasive (MI) and open (O) transforaminal lumbar interbody fusion (TLIF) in the treatment of cauda equina syndrome (CES) caused by lumbar disc herniation. METHODS: In total, 116 patients with CES associated with disc herniation underwent decompression and stabilization surgery from January 2005 to January 2020 in a single-center study, and data were collected and retrospectively analyzed...

BACKGROUND: With limited studies on spinal injuries occurring at the cervicothoracic junction, there is currently a knowledge gap regarding the correlation between morphology of injury and neurology and whether surgery provides a favorable neurological outcome. The primary objective was to determine whether the neurological deficit correlated with the severity of injury at this region of the spine. METHODS: All patients with injuries at the cervicothoracic junction from December 2015 to December 2020 in a government trauma hospital were included...

STUDY DESIGN: Cadaveric specimens. OBJECTIVE: To perform a pathomorphological analysis of the degree of facet joint (FJ) degeneration utilizing fresh cadaveric models and correlating these structural changes with imaging findings. METHODS: L1-L5 FSU including all tissue between the anterior longitudinal ligament to the posterior spinal structures were obtained on 28 patients at a mean of 5.7 hours post-mortem. The samples were fixed in an agar medium and CT and MRI were performed...

STUDY DESIGN: Delphi expert panel consensus. OBJECTIVE: To obtain expert consensus on best practices for appropriate telemedicine utilization in spine surgery. SUMMARY OF BACKGROUND DATA: Several studies have shown high patient satisfaction associated with telemedicine during the COVID-19 peak pandemic period as well as after easing of restrictions. As this technology will most likely continue to be employed, there is a need to define appropriate utilization...

STUDY DESIGN: Cross-sectional, international survey. OBJECTIVES: To evaluate the knowledge of spine surgeons regarding the use of electromyography (EMG) and nerve conduction studies (NCS) for degenerative cervical spine conditions (DCC). METHODS: All members of AO Spine International were emailed an anonymous survey to evaluate their clinical knowledge about the use of EMG and nerve conduction studies for DCC. Descriptive statistics were used to analyze the results, as well as to compare the answers among different groups of surgeons and assess demographic characteristics...

STUDY DESIGN: Narrative Review. OBJECTIVE: To (i) discuss why assessment and monitoring of disease progression is critical in Degenerative cervical myelopathy (DCM); (ii) outline the important features of an ideal assessment tool and (iii) discuss current and novel strategies for detecting subtle deterioration in DCM. METHODS: Literature review. RESULTS: Degenerative cervical myelopathy is an overarching term used to describe progressive injury to the cervical spinal cord by age-related changes of the spinal axis...

STUDY DESIGN: Retrospective review. OBJECTIVE: This study aimed to investigate if smokers have both poorer early clinical and radiologic outcomes in cervical laminoplasty when compared with nonsmokers. SUMMARY OF BACKGROUND DATA: Cigarette smoking had been reported to increase rates of pseudoarthrosis following spinal instrumentation with fusion. METHODOLOGY: A retrospective review of all patients who underwent open-door cervical laminoplasty was performed...

Laminectomy with instrumented fusion (LF) has demonstrated better prevention of ossification of posterior longitudinal ligament (OPLL) growth compared to laminoplasty (LP). There remains uncertainty, however, as to which surgical approach is more beneficial with respect to clinical outcomes and complications. We retrospectively reviewed 273 cervical OPLL patients of more than 3 levels, from the two institutions' databases, who underwent LF or LP between January 1998 and January 2016. Each 273 patient (85 with LF, 188 with LP) was assessed for postoperative neurologic and radiologic outcomes, complications and reoperations...

Background: Golf is a commonly played sport among older adults, and degenerative and/or deformity spine pathology can severely impact older individuals' ability to play golf. In a cohort of self-identified, avid golfers undergoing degenerative or deformity spine surgery, we report their: (I) presentation, (II) operative treatment, and (III) return-to-play (RTP) process. Methods: A retrospective case series of self-identified, avid golfers undergoing spine surgery at a single institution from 2015-2019 was undertaken...

Ankylosing spondylitis (AS) is an inflammatory disorder leading to ossification of joints and ligaments, resulting in autofusion throughout the spinal column. In patients with fixed, kyphotic cervical deformities, which cause an impaired horizontal gaze and severe neck pain, surgical intervention is warranted. Although several articles have described the anterior and/or posterior surgical treatments used to address the fixed kyphosis, few sources present the key operative steps and technical nuances. The purpose of this technical report was to provide detailed surgical steps, representative photographs, and an operative video demonstrating multilevel anterior cervical osteotomies, uncinatectomies, and a posterior osteotomy for the correction of a fixed cervical deformity secondary to AS...

Objectives: To summarize the current evidence on surgical treatment for large bridging osteophytes of the anterior cervical spine from Diffuse Idiopathic Skeletal Hyperostosis (DISH). Overview of Literature: In the current review, the surgical treatment of secondary dysphagia from DISH was the most useful treatment. We propose a treatment algorithm for management of this condition because currently there are only case reports and retrospective studies available. Methods: Literature search was performed using the MeSH terms "Anterior Cervical Osteophyte," "Diffuse Idiopathic Skeletal Hyperostosis (DISH)," and "Dysphagia" and "Treatment" for articles published between January 2000 and February 2020...
