The authors report four patients who presented with symptoms of cervical myelopathy. Investigations revealed a single level large cervical disc herniation that extended on the posterior surface of adjoining vertebral bodies and resulted in severe cord and root compression. From the investigations it was apparent that the posterior longitudinal ligament was essentially intact in all these cases. The patients underwent a facetal distraction-fixation surgery using Goel facetal spacers. Investigations in the immediate postoperative phase revealed a near complete disappearance of the disc bulge, restoration of the cervical cord girth and distraction-fixation-arthrodesis of the spinal segment...

BACKGROUND CONTEXT: Venous hypertensive myelopathy (VHM) results from spinal vascular malformations of arteriovenous shunting that increases spinal venous pressure, leading to congestive edema and neurologic dysfunction. There has been no report of VHM associated with cervical spondylotic myelopathy (CSM). PURPOSE: The aim of this study was to report an extremely rare case of VHM likely due to CSM. STUDY DESIGN: This study is a case report and review of the literature...

A 54-year-old woman came to our endocrinology clinics presenting with upper and lower extremity paresthesia, salt cravings, episodes of hypotension, fatigue and a long term history of depression. Physical exam was unremarkable. Cervical and brain MRI ordered by her neurologist three years ago revealed sella and pituitary normal in size, stable very small 3 mm pituitary incidentaloma and mild disc bulging. Basal pituitary hormonal screening showed low cortisol and ACTH levels. Insulin Tolerance Test and Glucagon Stimulation Test confirmed secondary ACTH deficiency with concomitant GH deficiency...

Most in vitro studies are limited in the ability to partition intervertebral disc (IVD) height loss from total specimen height loss since the net changes in the actuator position of the materials testing system simply reflect net changes to functional spinal units (FSUs) used for testing. Three levels of peak compressive force, three cycle rates and two dynamic postural conditions were examined using a full-factorial design. Cyclic compressive force was applied using a time-varying waveform with synchronous flexion/extension for 5000 cycles...

BACKGROUND CONTEXT: Bulging of ligamentum flavum can happen with the aging process and can lead to compression of the spinal cord and nerves. However, the distribution and the risk factors associated with a missed ligamentum flavum bulge (LFB) are unknown. PURPOSE: The aim was to evaluate the distribution and risk factors associated with missed LFB in the cervical spine. STUDY DESIGN: This was a retrospective analysis of kinematic magnetic resonance images (kMRI)...

BACKGROUND: Many studies have been developed to characterize the mechanical behavior of the intervertebral disc specifically for the lumbar spine and there have been limited studies done on the cervical spine with the goal to evaluate the strength of the cervical spine under compression without any information on the bulging of the intervertebral discs. The goal of the current study is to examine the deformation response of the cervical intervertebral disc classified with grade III or greater degeneration and analyze the relationship between axial deformation and anterior and posterior bulge under compression up to 550 N...

BACKGROUND: Adjacent segment disease (ASD) is common after cervical fusion. The aim of this study was to evaluate the risk factors for ASD on X-ray and magnetic resonance imaging (MRI). METHODS: Patients included in this study had received revision surgeries after developing symptomatic ASD following anterior decompression and fusion. A control group that had not developed ASD was matched 1:1 by follow-up time and fusion segments. Plate-to-disc distances (PDDs), developmental cervical canal stenosis on X-ray, cervical disc degeneration grading, and cervical disc bulge impingements on preoperative MRI were measured and compared between the ASD group and the control group...

INTRODUCTION: There is limited literature on the management of neglected healed (fused) bilateral cervical facet dislocation. The authors report a case of a middle aged male who developed a bilateral facet dislocation but only sought treatment 14 months post injury when he experienced pain and deformity in the cervical spine. CASE REPORT: A 42-year-old male was pushed into a 1.2-m pool by accident and hit his head on the bottom. He immediately felt a sharp pain in his neck but was able to get out of the pool by himself and at the emergency department was found to have no neurological deficit...

Spinal spondylosis is an extremely common condition that has only rarely been described as a cause of syringomyelia. We describe a case of syringomyelia associated with cervical spondylosis admitted at our division and treated by our institute. It is the case of a 66-year-old woman. At our observation she was affected by moderate-severe spastic tetraparesis. T2-weighted magnetic resonance imaging (MRI) showed an hyperintense signal within spinal cord from C3 to T1 with a more sharply defined process in the inferior cervical spinal cord...

Herniations of the cervical disk in plastic surgeons are far more common in practice than the paucity of reported cases would indicate. A likely explanation may be the peculiar, nonergonomic positions that plastic surgeons must hold during surgery while wearing a headlight and loupes. From January 2003 to December 2006, at Tri-Service General Hospital, Taiwan, 4 plastic surgeons experienced herniations of the cervical disk. Magnetic resonance imaging study indicated there was disk herniation or bulging with spinal cord impingement...

The patient was treated as pharyngeal foreign body sensation for six months. Laryngeal endoscopy: one about 1 cm x 2 cm x 2 cm, hard, smooth bulge in hypopharyngeal wall at the plane of epiglottis valley. The cervical MRI showed that the C3-C4 disc herniation and degeneration of the C3-C4 vertebrae. Cervical CT showed the C3-C4 disc osteophyte formation and forward bulge. After orthopedic consultation, the patient was diagnosed as esophageal cervical spondylosis. C3-C4 diskectomy and vertebral interbody bone grafted with plate fixation were undertaken...
