STUDY DESIGN: A retrospective study. OBJECTIVE: To identify preoperative risk factors causing cervical fifth nerve root palsy (C5 palsy) after laminectomy and fusion (LF). SUMMARY OF BACKGROUND DATA: It is well known that postoperative C5 palsy is not rare after cervical surgery. Although there remains controversy, C5 palsy is considered to be more common in patients who had LF than in those who had laminoplasty. However, the reason for the higher incidence of C5 palsy in patients with LF has been poorly understood...

INTRODUCTION: Cervical spinal cord herniation (SCH) is a rare clinical entity. Reported following prior intradural surgery or surgery complicated by durotomy, patients return several months to years later with symptoms of worsening myelopathy. Herein is presented a case of a 51-year old female with SCH in the cervical spine following kyphosis deformity correction CASE DESCRIPTION: A 51-year old female presented to the Neurosurgery clinic with worsening cervical myelopathy due to cervical spinal cord tethering and adhesions from prior intradural surgery for Chiari malformation...

STUDY DESIGN: Retrospective study. OBJECTIVES: The objective of this study was to find out whether ossification of posterior longitudinal ligament (OPLL) characteristics, including size, shape and subtype, can be used to diagnose myelopathy using somatosensory evoked potential (SEP) in cervical OPLL patients. SETTING: Yonsei University College of Medicine, Seoul, Korea. METHODS: We retrospectively reviewed the medical records of 153 cervical OPLL patients who underwent SEP study...

PURPOSE: The purpose of this study was to evaluate the clinical outcomes of atlanto-axial arthrodesis in rheumatoid arthritis (RA) patients with cervical myelopathy using the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ). METHODS: Twenty patients who underwent surgery to treat atlanto-axial subluxation (AAS) were reviewed. RESULTS: The rates of success rates for each domain were as follows: cervical spine function, 11 of 18 patients (61...

Cervical spondylotic myelopathy (CSM) is a functional disturbance in the spinal cord as a result of degenerative changes within the cervical spinal column. This review discusses the history of CSM and its diagnosis, including clinical presentation, physical exam, and imaging studies. The pathophysiology, natural history, and treatment options are also discussed with support of the recent literature.

STUDY DESIGN: Prospective cohort. OBJECTIVE: To explore the correlations between diffusion tensor imaging (DTI) ratios and diffusion tensor tractography (DTT) grading with clinical symptoms and outcomes of cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA: In addition to magnetic resonance imaging (MRI) and computed tomography, DTI may be useful in understanding pathophysiology of spinal cord in earlier stages of the CSM but it may be confounded by age and cervical level, and previous studies had small sample sizes...

STUDY DESIGN: A cross-sectional study. OBJECTIVE: The aim of this study was to assess fatty infiltration and asymmetry of the multifidus (MF), semispinalis cervicis (SCer), semispinalis capitis (SCap), and splenius capitis (SPL) muscles in patients with degenerative cervical myelopathy (DCM), and evaluate their correlations with clinical symptoms and functional scores. SUMMARY OF BACKGROUND DATA: Cervical muscle alterations have been reported in patients with chronic neck pain, but the assessment of cervical muscle morphology has been overlooked in patients with DCM...

Both general anesthesia (GA) and cervical plexus anesthesia (CPA) can be used for anterior cervical discectomy and fusion (ACDF) surgery. The aim of this study was to evaluate the influence of anesthetic techniques on perioperative mortality and morbidity in patients undergoing cervical surgery.From January 2008 to December 2015, 356 patients who underwent 1-level ACDF for cervical spinal myelopathy were prospectively reviewed. They were assigned to receive GA (group A) and CPA (group B). The analgesic efficacy of the block was assessed by anesthesia preparation time, the maximum heart rate, and mean arterial blood pressure changes compared with the baseline, time of postoperative revival, and duration of recovery stay...

PURPOSE: Laminectomy with lateral mass screw fixation has been proven to be an effective method to treat the multilevel cervical degenerative myelopathy and severe cervical spondylosis. However, accurate and safe insertion of the lateral mass screw is technically demanding due to the individual variations of the anatomy of the lateral mass of the subaxial cervical spine. Misplaced lateral mass screw is not uncommon, and operation-related complications still beset the surgeons, which may impair the clinical outcomes...

A 38-year-old man was healthy before presenting to our clinic with pain and marked weakness in the right upper extremity. He stated that the symptoms developed the day after he accidentally fell asleep while playing with his Smartphone half-lying on his back with two thick pillows supporting his upper back. Physical examination revealed significant increase in deep tendon reflexes in the lower extremities and clonus. Hoffman's sign was positive in the left upper extremity. Magnetic resonance image showed high signal change on T2-weighted images of the left spinal cord at the C4-5 level, which was indicative of compression myelopathy...

Background and Study Aims Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in the elderly population. Surgery is usually successful in preventing any deterioration, as well as improving functional status and quality of life. This study assesses the safety and efficacy of minimally invasive microscopic posterior cervical decompression for the treatment of CSM. Materials and Methods A retrospective review of patients with myelopathy from cervical stenosis treated with minimally invasive posterior cervical decompression was performed...

Reported is a case of a man aged 55 years who presented with progressive spastic paraparesis. Examination demonstrated multiple cutaneous telangiectases. Subsequent development of upper limb weakness, acute urinary retention and eventual respiratory compromise resulted in the requirement for intensive care unit admission and mechanical ventilation. MRI spine revealed diffuse T2 hyperintensity in the cervical cord with enhancement and cord expansion. Immunomodulatory therapy for a presumed diagnosis of transverse myelitis yielded no response, so a vascular aetiology was suspected...

PURPOSE: To determine whether radiological, clinical, and demographic findings in patients with cervical spondylotic myelopathy (CSM) were independently associated with loss of cervical lordosis (LCL) after laminoplasty. METHODS: The prospective study included 41 consecutive patients who underwent laminoplasty for CSM. The difference in C2-7 Cobb angle between the postoperative and preoperative films was used to evaluate change in cervical alignment. Age, sex, body mass index (BMI), smoking history, preoperative C2-7 Cobb angle, T1 slope, C2-7 range of motion (C2-7 ROM), C2-7 sagittal vertical axis (C2-7 SVA), and cephalad vertebral level undergoing laminoplasty (CVLL) were assessed...
