Total thyroidectomy, radioiodine (RAI) therapy, and TSH suppression are the mainstay treatment for differentiated thyroid carcinomas (DTCs). Treatments for metastatic disease include surgery, external-beam radiotherapy, RAI, and kinase inhibitors for progressive iodine-refractory disease. Unresectable locoregional disease remains a challenge, as standard therapy with RAI becomes unfeasible. We report a case of a young patient who presented with unresectable papillary thyroid carcinoma (PTC), and treatment with sorafenib allowed total thyroidectomy and RAI therapy...

BACKGROUND: Few studies have addressed in detail long-term degenerative changes in the cervical spine. In this study, we evaluated the progression of degenerative changes of the cervical spine that occurred over a 20-year period in an originally healthy cohort. We also sought to clarify the relationship between the progression of cervical degenerative changes and the development of clinical symptoms. METHODS: For this prospective follow-up investigation, we recruited 193 subjects from an original cohort of 497 participants who had undergone magnetic resonance imaging (MRI) of the cervical spine between 1993 and 1996...

Introduction: High cervical myelopathy can be rarely caused by the developmental anomalies of atlas. Patients with C1 arch stenosis can present in early childhood or later in life. In symptomatic patients, posterior decompression at atlas is mandatory. We report the first clinical series of 20 patients of C1 arch stenosis in the English literature. Materials and Methods: This is retrospective case series having a cohort of 20 patients with congenital C1 arch stenosis...

PURPOSE: Correction surgery for cervical degenerative kyphosis (CDK) may carry a greater risk of causing neural complications such as spinal cord injury and C5 nerve palsy because spinal canal stenosis, osteoarthritis of the facet, and consequent foraminal stenosis may coexist with CDK. We have produced an algorithmic strategy of surgical intervention for CDK, and report the outcome. METHODS: Thirty-one patients who underwent correction surgery for CDK, with a kyphotic angle of 20° or more (from 20 to 74) were involved...

Cervical spondylotic myelopathy (CSM) is a degenerative pathology characterized by partial or complete conduction block on intraoperative neuromonitoring. We describe a case treated using osseoligamentous decompression and durotomy for cerebrospinal fluid (CSF) release. Intraoperative monitoring demonstrated immediate signal improvement with CSF release, suggesting that clinical improvement in CSM may result from resolution of CSF flow anomalies.

Preoperative foraminal stenosis at C4/5 is a predisposing risk factor for C5 nerve root palsy in elderly patients. However, the area of the C4/5 intervertebral foramen and its relationship to the extent of arthrosis and lower foraminal areas (C5/6 and C6/7) are unknown. The authors sought to compare the areas of the cervical intervertebral foramen at the C4/5, C5/6, and C6/7 levels, noting any differences across race or sex and the relationship between foraminal area and arthrosis grade. A total of 600 cervical foramina from an osseous collection were examined...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is the most common cause of cord dysfunction in older individuals. CSM involves either the upper motor neuron or lower motor neuron (LMN) in the cervical spine. The neurological level of the LMN lesion does not usually correspond with the structural level detected via magnetic resonance imaging (MRI) OBJECTIVE: To examine the relationship between the structural level of stenosis and the neurological level of LMN involvement in patients with CSM DESIGN: Retrospective descriptive study SETTING: Tertiary hospital PATIENTS: Patients with cervical spondylotic myelopathy, aged 41 to 79 years METHODS: We reviewed electromyography (EMG) and magnetic resonance imaging (MRI) findings from 17 patients with CSM to objectively show the relationship between the structural level of stenosis and the neurological level with lower motor neuron involvement...

BACKGROUND: Anterior endoscopic techniques in cervical disc were found to be effective and safe. We report our experience of 210 patients of endoscopic disc removal by anterior approach which is largest series for management of cervical myelopathy. METHODS: Visual analogue scale (VAS) and Nurick grading system was used to assess severity of neck and arm pain and functional outcomes respectively. Myelopathy (with or without unilateral or bilateral radiculopathy), or the unilateral radiculopathy having either soft or hard disc prolapsed were included...

BACKGROUND AND PURPOSE: Internal carotid dissection is a frequent cause of ischemic stroke in young adults. It may cause tandem occlusions in which cervical carotid obstruction is associated with intracranial proximal vessel occlusion. To date, no consensus has emerged concerning endovascular treatment strategy. Our aim was to evaluate our endovascular "distal-to-proximal" strategy in the treatment of this stroke subtype in the first large multicentric cohort. MATERIALS AND METHODS: Prospectively managed stroke data bases from 2 separate centers were retrospectively studied between 2009 and 2014 for records of tandem occlusions related to internal carotid dissection...

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention...

INTRODUCTION: This is a narrative overview of the pathophysiology, investigation and management of Degenerative Cervical Myelopathy (DCM). This review article also takes a look ahead to the impact high resolution MRI may have on treatment. BACKGROUND: DCM is the most common cause of spinal dysfunction and yet it remains poorly understood. It is becoming increasingly common in our ageing population. Disc and facet joint abnormalities, osteophytes, spondylothisthesis and ligamentous hypertrophy all act together to produce spinal canal and neuronal foramina stenosis which in turn causes neural compromise...

BACKGROUND: To compare morphometric factors of cervical spine in the cervical stenosis on dynamic and static magnetic resonance imaging. To analyse the relationship between the severity of myelopathy and morphometric parameters. METHODS: Patients with cervical canal stenosis scanned with MRI in neutral (N), flexion (F) and extension (E) positions were retrospectively reviewed. All cases were evaluated in Nurick and Muhle grades. Following parameters were measured: anterior and posterior length of the cervical cord (aLCC, pLCC), mid-cord distance (L value), cervical cord angle (CCA), cervical lordosis, spine/cord (S/C) angle ratio, spinal cord (SC) area, cerebrospinal fluid (CSF) area, and CSF reserve ratio (CSF/CSF plus SC)...

Introduction: Hemidiaphragm paralysis secondary to phrenic nerve palsy is a well-recognised medical condition. There are few case reports in the literature documenting resolution of hemidiaphragm paralysis following cervical spine surgery. This case report documents our experience with one such case. Case Presentation: A 64-year-old man was referred to the orthopaedic service with right hemidiaphragm paralysis. He had a previous history of asbestos exposure and polio and was initially seen and investigated by the respiratory physicians...

OBJECTIVE: Anterior cervical corpectomy and fusion (ACCF), in which a ventral constriction is resected, can decompress myelopathy and is considered the optimal treatment for ossification of the posterior longitudinal ligament (OPLL) up to now. However, its disadvantages are incomplete decompression, high surgery- and implant-related complication rates, and extremely surgical technique demanding. Our object was to introduce anterior controllable antedisplacement fusion (ACAF), a new surgical technique to treat OPLL, and compare it with ACCF...
