Surgical Highways to the Craniovertebral Junction: Is It Time for a Reappraisal?
2019
Background: The craniovertebral junction (CVJ) can be affected by a variety of congenital or acquired anomalies. Because of its complexity, a careful evaluation of bones and ligamentous structures in all three planes is required. This can be achieved by studying the CVJ in terms of several anatomical and radiological lines that have been visualized to facilitate understanding of its surgical anatomy. In this study we aimed to review the state-of-the art craniometric CVJ lines and approaches. Methods: In December 2016 a PubMed search was performed, including the search terms ‘CVJ surgical approach/line’, ‘cervical approach’, ‘craniometric measurement’, ‘CVJ anatomy’ and ‘ventral/dorsal/far-l…
Upper thoracic-spine disc degeneration in patients with cervical pain.
2003
To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established.One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion.Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affecte…
Significance of immunohistochemistry biomarkers in prediction of malignant transformation of oral lichen planus
2022
Background: Oral lichen planus (OLP) is a chronic inflammatory disorder with increased risk for malignant transformation. Biomarker validation is a pivotal step in moving newly discovered biomarkers towards clinical implementation. We performed a systematic review of studies on biomarkers related to OLP, wherein biomarkers have been described in at least two independent studies. Our aim was to determine whether any of these biomark-ers might be promising in predicting the increased risk of malignant transformation of OLP. Material and Methods: We searched the following databases until August 2021: PUBMED, EMBASE, and Web of Science. Due to high heterogeneity, a qualitative rather than quant…
Financial Aspects of Cervical Disc Arthroplasty: A Narrative Review of Recent Literature
2020
Recently, there has been significant interest in understanding the cost-effectiveness of treatments in spine surgery as health care systems in the United States move toward value-based care and alternative payment models. Previous studies have shown comparable outcomes of cervical disc arthroplasty (CDA) and anterior cervical discectomy fusion; however, there is a lack of consensus on the cost-effectiveness of CDA to support full adoption. Evidence of the limitations of these cost-analysis studies also exists in the literature, including industry funding, potential selection bias, and varying methods of calculating value. The goal of this narrative review is to provide an overview of the co…
Association of long-term outcome of long cervical fusion with sagittal balance: the significance of T1 slope minus cervical lordosis
2022
Introduction. Retrospective study to assess correlation between the sagittal alignment of the cervical spine and the long-term outcomes of long cervical fusion due to cervical spondylotic myelopathy (CSM), with the emphasis on T1 slope minus cervical lordosis (T1S-CL).Summary of background data. Growing evidence shows that the sagittal profile can play a major role in the outcomes of treatment, but the role of its correction is yet to be established. Material and methods. We conducted a retrospective analysis of 54 patients treated for CSM from 2006 to 2012. The neck pain-related disability was measured using NDI, the myelopathy was measured with the mJOA and Nurick scales. Six years after …
DOUBLE TRANSVERSE FORAMEN IN INFANTILE CERVICAL VERTEBRAE OF THE LATE 17TH AND EARLY 18TH CENTURIES. Doble foramen transverso en las vértebras infant…
2016
La presencia de doble foramen transverso es una variante anatómica que se observa con frecuencia en el raquis cervical inferior y que presenta implicaciones clínicas en relación con la arteria vertebral. Aunque en la actualidad existe cierta controversia acerca de si el origen de esta variante cervical es congénito o adquirido, y a pesar de que la presencia de doble foramen transverso en población infantil descartaría un origen degenerativo-artrósico, se encuentra una falta de información acerca de su presencia en vértebras cervicales infantiles. En este sentido, nuestro objetivo ha sido analizar la presencia de doble foramen transverso en vértebras cervicales infantiles procedentes de rest…

Focus on functional delayed central sleep apnea following cervical laminectomy. An example of respiratory dysfunction in restorative neurosurgical pr…
2017
In sleep-related breathing disorders, sleep apnea is a clinical symptom that can be categorized as obstructive sleep apnea (OSA) or mixed apnea by analysis using poly-somnography. The occurrence of delayed central sleep apnea (CSA) is an extremely rare complication of cervical laminectomy for spondylotic myelopathy. So far only three studies concerning such an event have been reported in the literature. Naim-ur-Rahman, in 1994, reported a case of postoperative CSA following C3-C6 laminectomy, and Visocchi and colleagues, in 2014, in two studies, stressed the lack of association with any other neurological sign of spinal cord damage. No definitive mechanism has been recognized so far for del…
DEGENERATIVE CERVICAL MYELOPATHY: REVIEW OF SURGICAL OUTCOME PREDICTORS AND NEED FOR MULTIMODAL APPROACH
2020
Degenerative cervical myelopathy is the most common cause of spinal cord injury in the elderly population in the developed world, and it significantly affects the quality of life of patients and their caregivers. Surgery remains the only treatment option able to halt disease progression and provide neurological recovery for most patients. Although it has remained challenging to predict exactly who will experience improvement after surgery, increasingly it has been shown that clinical, imaging, and electrophysiological factors can predict, with relatively good capacity, those more likely to benefit. Clinically, the baseline neurological impairment appears to be strongly related to the outcom…
