Introduction And Importance: Cervical spinal stenoses is becoming more and more common due to the aging population. The degenerative changes in the spine including discopathy or spondylosis will constrict and narrow the spinal canal and the usual site for the stenoses is in the cervical and lumbar region. The mainstay of the treatment is surgical, however there still a controversy regarding which approach is the best for the patient with cervical stenoses. Read More

Arbeitsgemeinschaft Freier Wirbelsäulenchirurgen, Vienna, Austria.

Background: Lumbar spinal stenosis results from spinal canal narrowing and can lead to pain and dysfunction. Until recently, surgical treatment for lumbar spinal stenosis requiring an extensive decompression, with or without spondylolisthesis, had to balance pain relief with the long-term risks of spinal instability after decompression and adjacent segment disease (ASD) after spinal fusion. Spinal motion-preserving devices aim to reduce the incidence of ASD after posterolateral fusion and consequent need for revision surgery. Read More

Introduction Cervical spondylotic myelopathy (CSM) describes a neurological deficit related to the spinal cord due to the changes in the facet joints and discs of the cervical spine as a result of degeneration. Diagnosis is mainly dependent on imaging. Diffusion tensor tractography (DTT), being a non-invasive technique, shows better sensitivity when compared to the conventional T2WI sequence in the early detection of cervical spondylotic myelopathy (CSM).

Introduction: Although mostly used in the management of spinal trauma, hard collar immobilisation is also used as an adjunct to recovery after elective cervical spine surgery. Many surgeons believe that bracing reduces the risk of non-union and pain and provides a subjective sense of security for patients. There is little if any, evidence for this practice and immobilisation can be a direct cause of adverse events. Read More

Although patients with diabetes reportedly have more peripheral neuropathy, the impacts of diabetes on postoperative recovery in pain and patient-reported outcome measures (PROMs) after laminoplasty for cervical spondylotic myelopathy (CSM) is not well characterized. The authors aimed to elucidate the effects of diabetes on neck/arm/hand/leg/foot pain and PROMs after laminoplasty CSM. The authors retrospectively reviewed 339 patients (82 with diabetes and 257 without) who underwent laminoplasty between C3 and C7 in 11 hospitals during April 2017 -October 2019. Read More

Background: The objective of the present isolated spine study was to evaluate the kinematic differences between groups of normal and degenerated cervical spine specimens. Previous studies on cervical spine degeneration support the existence of the unstable phase during the degeneration process; however, there is a lack of quantitative data available to fully characterize this early stage of degeneration.

Method: For this effort five degenerated and eight normal cervical spines (C2-T1) were isolated and were subject to pure bending moments of flexion, extension, axial rotation and lateral bending. Read More

Division of Radiology and Nuclear Medicine, Oslo University Hospital, Oslo, Norway.

Background: Cervical spondylosis is the degeneration of cervical spine often associated with aging and neck pain. As the degenerative changes are coupled with altered osteoblastic activity, imaging modalities sensitive to such molecular changes could be valuable for clinical assessment, disease prophylaxis, and monitoring early therapy response. In this study, we examined the role of F-sodium fluoride-positron emission tomography/computed tomography (F-NaF-PET/CT) in detecting age-associated changes in the cervical spine of an adult population with broad age spectrum.

Management of patients after lumbar spine surgery or interventional radiology can be complex, and postoperative imaging patterns are often poorly understood by nonspecialized radiologists. This article focuses on postoperative imaging features of the lumbar spine in five clinical settings (with corresponding interventions): vertebral osteoporotic fractures (percutaneous vertebroplasty and vertebral augmentation), lumbar disk herniation (surgical diskectomy and percutaneous interventional radiology), lumbar spinal stenosis (surgical decompression), lumbar spondylolisthesis (surgical decompression and fusion), and degenerative scoliosis (techniques of osteotomies).For each intervention, we discuss imaging indications, depending if the patient is asymptomatic or if there are suspected complications, describe normal and pathologic imaging features, and present key points.

Introduction: Patients with cervical spondylosis have a high incidence of difficult airway, and unpredicted difficult intubation may be life-threatening. Traditional predictors and imaging data may suggest a difficult airway, but these data have limited predictive value, with low sensitivity and specificity. Ultrasonography is a non-irradiating, reproducible, inexpensive and simple tool that provides good imaging of the cervical soft tissue for airway assessment. Read More

Objective: To evaluate the reliability and usefulness of cervical flexion/extension magnetic resonance imaging (MRI) as a tool for decision-making regarding treatment of symptomatic cervical spondylosis.

Methods: We prospectively collected demographic, clinical, and flexion/neutral/extension MRI data for consecutive 24 patients who had presented with symptomatic cervical degenerative disease. From the survey responses, we analyzed the agreement between clinical interpretation and judgment when neutral MRI (nMRI) versus flexion/extension MRI (fMRI/eMRI) had been provided. Read More

Objective: Patients with ankylosing spinal disorders (ASDs), including ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH), have been shown to experience significantly increased rates of postoperative complications. Despite this, very few risk stratification tools have been validated for this population. As such, the purpose of this study was to identify predictors of adverse events and mortality in ASD patients undergoing surgery for 3-column fractures. Read More

Isthmic spondylolisthesis can be defined as the anterior translation of a vertebral body relative to the one subjacent to it and secondary to an abnormality of the pars interarticularis. Isthmic spondylolisthesis is usually asymptomatic and discovered as an incidental radiographic finding. However, it can be symptomatic due to its biomechanical effects on the adjacent neural structures and patients may present with low back and/or radicular leg pain. Read More

Case: We report 3 cases of thoracic myelopathy caused by vertebral osteophytes and coexisting intradural spinal arachnoid cyst (SAC), which was difficult to diagnose on preoperative magnetic resonance imaging. Intraoperative ultrasound sonography revealed spinal cord impingement because of osteophytes and a pulsating intradural SAC. Repeated pincer compression on the spinal cord seemed to be associated with their paraparetic symptoms. Read More
