No abstract text is available yet for this article.

OBJECTIVE: Focal cervical kyphotic deformity (FCK) without neurologic compression is not uncommon in patients with cervical spondylotic myelopathy (CSM) who underwent anterior cervical decompression and fusion (ACDF) surgery. It remains unclear whether FCK at non-responsible levels needs to be treated simultaneously. This study aims to investigate whether FCK at non-responsible levels is the prognostic factor for CSM and elucidate the surgical indication for FCK. METHODS: Patients with CSM who underwent ACDF between January 2016 and April 2021 were included...

BACKGROUND AND PURPOSE: Simultaneous assessment of neurodegeneration in both the cervical cord and brain across multiple centres can enhance the effectiveness of clinical trials. Thus, this study aims to simultaneously assess microstructural changes in the cervical cord and brain above the stenosis in degenerative cervical myelopathy (DCM) using quantitative magnetic resonance imaging (MRI) in a multicentre study. METHODS: We applied voxelwise analysis with a probabilistic brain/spinal cord template embedded in statistical parametric mappin (SPM-BSC) to process multi parametric mapping (MPM) including effective transverse relaxation rate (R2*), longitudinal relaxation rate (R1), and magnetization transfer (MT), which are indirectly sensitive to iron and myelin content...

PURPOSE: Degenerative cervical myelopathy (DCM) is the commonest cause of adult spinal cord dysfunction worldwide, for which surgery is the mainstay of treatment. At present, there is limited literature on the costs associated with the surgical management of DCM, and none from the United Kingdom (UK). This study aimed to evaluate the cost-effectiveness of DCM surgery within the National Health Service, UK. MATERIALS AND METHODS: Incidence of DCM was identified from the Hospital Episode Statistics (HES) database for a single year using five ICD-10 diagnostic codes to represent DCM...

STUDY DESIGN: Basic Science. OBJECTIVE: The objective of this study was to identify a unique serum profile of circulating miRNAs and inflammatory markers in patients with degenerative cervical myelopathy (DCM) compared to healthy controls (HC). SUMMARY OF BACKGROUND DATA: Currently, DCM is diagnosed with a combination of history, physical examination, and close correlation to advanced imaging. To date, no serum marker has been identified to be diagnostic of this condition...

A 67-year-old man with cervical spondylotic myelopathy undergoing conservative treatment presented with subacute progression of fine motor and ambulatory disturbances, leading to admission at a previous hospital. Pre-cervical laminoplasty chest computed tomography (CT) revealed a tumor in the left upper lobe of the lung, prompting transfer to our institution. Transbronchial biopsy findings were consistent with adenocarcinoma, diagnosed as clinical stage T2bN0M0, Stage IIA. The neurological abnormalities could not be solely attributed to cervical spondylotic myelopathy, leading to a diagnosis of concurrent paraneoplastic neurological syndrome (PNS)...

STUDY DESIGN: Retrospective analysis of a prospective, multicenter registry. OBJECTIVE: To assess whether upper or lower limb mJOA improvement more strongly associates with patient satisfaction after surgery for cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA: The modified Japanese Orthopaedic Association (mJOA) is commonly used to assess functional status in patients with CSM. Patients present with upper and/or lower extremity dysfunction, and it is unclear whether improvement in one and/or both symptoms drives postoperative patient satisfaction...

OBJECTIVE: The authors present a finite element analysis (FEA) evaluating the mechanical impact of C1-2 hypermobility on the spinal cord. METHODS: The Code_Aster program was used to perform an FEA to determine the mechanical impact of C1-2 hypermobility on the spinal cord. Normative values of Young's modulus were applied to the various components of the model, including bone, ligaments, and gray and white matter. Two models were created: 25° and 50° of C1-on-C2 rotation, and 2...

INTRODUCTION AND IMPORTANCE: One of the uncommon causes of ischaemic myelopathy is fibrocartilaginous embolisation, which results from the intersomatic disc nucleus pulposus becoming embolised into the spinal vasculature during Valsalva-like manoeuvres. CASE PRESENTATION: A 29-year-old female patient presented to the authors' emergency department with general weakness, dizziness, and an inability to move her right hand after a minor trauma. These symptoms deteriorated suddenly until the patient became quadriplegic...

The natural history of spinal cord cavernous malformation (SCM) may be characterized by recurrent episodes of hemorrhage resulting in a range of neurologic deficits, most of which are microhemorrhage and subsequent gliosis that can lead to progressive myelopathy. Macrohemorrhage with acute onset of symptoms is extremely rare and leads to irreversible neurologic deficits. In this article, we present an unusual case of ruptured cavernous malformation (CM) in the cervical spinal cord with large extralesional hemorrhage...

STUDY DESIGN: Retrospective review of prospectively collected data. OBJECTIVE: To determine the impact of preoperative symptom duration on postoperative functional outcomes following cervical disc replacement (CDR) for radiculopathy. SUMMARY OF BACKGROUND DATA: CDR has emerged as a reliable and efficacious treatment option for degenerative cervical spine pathologies. The relationship between preoperative symptom duration and outcomes following CDR is not well established...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: The objective of this study is to determine whether the presence of cerebrospinal fluid is associated with the severity of degenerative cervical myelopathy or postoperative outcomes. SUMMARY OF BACKGROUND DATA: Degenerative cervical myelopathy (DCM) is a clinical diagnosis characterized as neurologic dysfunction. Preoperative imaging is used to determine the source of cord compression. In clinical practice, cerebrospinal fluid (CSF) around the cord is often used as an indicator to determine whether stenosis is relevant...

BACKGROUND CONTEXT: Degenerative cervical myelopathy (DCM) is the most common form of atraumatic spinal cord injury globally. Degeneration of spinal discs, bony osteophyte growth and ligament pathology results in physical compression of the spinal cord contributing to damage of white matter tracts and grey matter cellular populations. This results in an insidious neurological and functional decline in patients which can lead to paralysis. Magnetic resonance imaging (MRI) confirms the diagnosis of DCM and is a prerequisite to surgical intervention, the only known treatment for this disorder...

BACKGROUND: Despite an abundance of literature on degenerative cervical myelopathy (DCM), little is known about pre-operative expectations of these patients. PURPOSE: The primary objective was to describe patient pre-operative expectations. Secondary objectives included identifying patient characteristics associated with high pre-operative expectations and to determine if expectations varied depending on myelopathy severity. STUDY DESIGN: This was a retrospective study of a prospective multicenter, observational cohort of patients with DCM...

Objectives and Background : To present a novel technique of treatment for a patient with basilar invagination. Basilar invagination (BI) is a congenital condition that can compress the cervicomedullary junction, leading to neurological deficits. Severe cases require surgical intervention, but there is debate over the choice of approach. The anterior approach allows direct decompression but carries high complication rates, while the posterior approach provides indirect decompression and offers good stability with fewer complications...

Background/Objectives: Expansive open-door laminoplasty results in favorable clinical outcomes for cervical myelopathy. However, some postoperative complications associated with surgical invasiveness, such as axial neck pain and kyphosis, have not been resolved. The use of an exoscope, which is a recently introduced novel magnification tool, allows for traditional open-door laminoplasty with minimal invasiveness. Therefore, we propose the use of exoscopic minimally invasive open-door laminoplasty (exLAP) and present its clinical outcomes during the acute postoperative period...

PURPOSE: This study aimed to compare cervical sagittal parameters and clinical outcomes between patients undergoing cervical laminoplasty(CL) and those undergoing lateral mass screw fixation(LMS). METHODS: We retrospectively studied 67 patients with multilevel ossification of the posterior longitudinal ligament (OPLL) of the cervical spine who underwent lateral mass screw fixation (LMS = 36) and cervical laminoplasty (CL = 31). We analyzed cervical sagittal parameters (C2-7 sagittal vertical axis (C2-7 SVA), C0-2 Cobb angle, C2-7 Cobb angle, C7 slope (C7s), T1 slope (T1s), and spino-cranial angle (SCA)) and clinical outcomes (visual analog scale [VAS], neck disability index [NDI], Japanese Orthopaedic Association [JOA] scores, recovery rate (RR), and minimum clinically significant difference [MCID])...

A 70-year-old female presented with bilateral numbness in her upper limbs. She was diagnosed with cervical spondylotic myelopathy and underwent cervical laminoplasty. However, there was no significant improvement in sensory disturbance, and at 6 months after surgery, she developed subacute motor and gait disturbance in four extremities. Spinal MRI revealed a long lesion of the spinal cord with edema, and a part of the lesion showed gadolinium contrast enhancement. Bronchoscopy revealed an elevated CD4/8 ratio, and gallium scintigraphy demonstrated an accumulation in the hilar lymph nodes, leading to a diagnosis of neurosarcoidosis...

STUDY DESIGN: A retrospective cohort study using prospectively collected data. OBJECTIVE: The aim of this study was to investigate preoperative differences in racial and socioeconomic factors in patients undergoing laminoplasty (LP) versus laminectomy and fusion (LF) for degenerative cervical myelopathy (DCM). SUMMARY OF BACKGROUND DATA: DCM is prevalent in the United States, requiring surgical intervention to prevent neurological degeneration...
