Background: Neuroimaging is indicated in most instances of new-onset myelopathy for clinico- radiological correlation in terms of diagnosis, recovery, and prediction of recurrence. Aim: This study was conducted to study the clinical profile of cases of Compressive Myelopathy and the pattern of spinal cord involvement, also to compare the sites of localisation of clinical diagnosis with MRI diagnosis. Methodology: The present study was a prospective study involving 30 patients. Patients with clinical suspicion of spinal cord disease of age group 20-80 years were included as study participants. The primary pulse sequences included T1 and T2 weighted images on MRI, the location of the lesion, its margins, signal intensity on both T1 and T2 weighted images was noted. Results: The majority of 53.33% of participants were aged between 51 to 60 years. Difficulty in walking was observed in 97% of participants. Men were more often affected than women. Cervical spondylosis was the commonest cause of compressive myelopathy in 57%. A most common pattern of spinal cord involvement was combined Anterior + Posterior cord involvement. The cervical site of localisation (54%) was the commonest followed by the thoracic and lumbar spinal cord. Conclusion: Myelopathies have male preponderance. The commonest cause of compressive myelopathy was Cervical spondylosis. Anterior plus posterior cord syndrome was the commonest pattern seen, followed by posterior cord syndrome, anterior cord syndrome being the least observed. MRI correlates well with a clinical diagnosis and is useful in suggesting the location of the lesion.

  • Spinal Injury
    SPINAL INJURY Presented by:- Bhagawati Ray DEFINITION Spinal cord injury (SCI) is damage to the spinal cord that results in a loss of function such as mobility or feeling. TYPES OF SPINAL CORD INJURY Complete Spinal Cord Injuries Complete paraplegia is described as permanent loss of motor and nerve function at T1 level or below, resulting in loss of sensation and movement in the legs, bowel, bladder, and sexual region. Arms and hands retain normal function. INCOMPLETE SPINAL CORD INJURIES Anterior cord syndrome Anterior cord syndrome, due to damage to the front portion of the spinal cord or reduction in the blood supply from the anterior spinal artery, can be caused by fractures or dislocations of vertebrae or herniated disks. CENTRAL CORD SYNDROME Central cord syndrome, almost always resulting from damage to the cervical spinal cord, is characterized by weakness in the arms with relative sparing of the legs, and spared sensation in regions served by the sacral segments. POSTERIOR CORD SYNDROME Posterior cord syndrome, in which just the dorsal columns of the spinal cord are affected, is usually seen in cases of chronic myelopathy but can also occur with infarction of the posterior spinal artery. BROWN-SEQUARD SYNDROME Brown-Sequard syndrome occurs when the spinal cord is injured on one side much more than the other. It is rare for the spinal cord to be truly hemisected (severed on one side), but partial lesions due to penetrating wounds (such as gunshot or knife wounds) or fractured vertebrae or tumors are common. CAUDA EQUINASYNDROME Cauda equina syndrome (CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged.

  • Spinal Cord Injury and Compression
    Page 1 of 10 View this article online at: patient.info/doctor/spinal-cord-injury-and-compression Spinal Cord Injury and Compression See also the separate article on Whiplash and Cervical Spine Injury. Acute spinal cord compression is a neurosurgical emergency. Rapid diagnosis and management are essential to have the highest chances of preventing permanent loss of function. The spinal cord extends from the base of the skull and terminates near the lower margin of the L1 vertebral body. Below L1, the spinal canal contains the lumbar, sacral and coccygeal spinal nerves that comprise the cauda equina. Therefore, injuries below L1 involve the segmental spinal nerves and/or cauda equina. Injuries above the termination of the spinal cord at L1 often involve both spinal cord lesions and segmental root or spinal nerve injuries. The incidence of traumatic spinal cord injury in Western Europe is about 16 per million.[1] Spinal cord injury in children is relatively rare.[2] A traumatic spinal cord injury is a lesion of neural elements of the spinal cord that can result in any degree of sensory and motor deficit, and autonomic or bowel dysfunction.[3] Spinal cord injuries may be primary or secondary: Primary injuries arise from a variety of mechanisms, including mechanical disruption, transection, penetrating injuries due to bullets or weapons, vertebral fracture/subluxation or displaced bony fragments causing penetrating spinal cord and/or segmental spinal nerve injuries. The primary traumatic impact initiates vascular and chemical processes leading to oedema and ischaemia which can lead to secondary injuries. Further cord insult can occur through subsequent inappropriate manual handling following trauma.

  • Spinal Cord Injury Cord Spinal on Perspectives International
    INTERNATIONAL PERSPECTIVES ON SPINAL CORD INJURY “Spinal cord injury need not be a death sentence. But this requires e ective emergency response and proper rehabilitation services, which are currently not available to the majority of people in the world. Once we have ensured survival, then the next step is to promote the human rights of people with spinal cord injury, alongside other persons with disabilities. All this is as much about awareness as it is about resources. I welcome this important report, because it will contribute to improved understanding and therefore better practice.” SHUAIB CHALKEN, UN SPECIAL RAPPORTEUR ON DISABILITY “Spina bi da is no obstacle to a full and useful life. I’ve been a Paralympic champion, a wife, a mother, a broadcaster and a member of the upper house of the British Parliament. It’s taken grit and dedication, but I’m certainly not superhuman. All of this was only made possible because I could rely on good healthcare, inclusive education, appropriate wheelchairs, an accessible environment, and proper welfare bene ts. I hope that policy-makers everywhere will read this report, understand how to tackle the challenge of spinal cord injury, and take the necessary actions.” TANNI GREYTHOMPSON, PARALYMPIC MEDALLIST AND MEMBER OF UK HOUSE OF LORDS “Disability is not incapability, it is part of the marvelous diversity we are surrounded by. We need to understand that persons with disability do not want charity, but opportunities. Charity involves the presence of an inferior and a superior who, ‘generously’, gives what he does not need, while solidarity is given between equals, in a horizontal way among human beings who are di erent, but equal in their rights.

  • Spinal Cord Injury (SCI) 30/03/2012
    Version 2.1 Spinal Cord Injury (SCI) 30/03/2012 Introduction The spinal cord extends from foramen magnum to the lower margin of L1 vertebral body. Below L1 is the cauda equina (lumbar, sacral, and coccygeal spinal nerve rootlets). Spinal cord injuries classified as complete or incomplete depending on any motor or sensory function remaining below the level of the injury. Causes The most common causes of spinal cord injury are: • Motor vehicle accidents • Violent assaults, gunshot wounds • Falls • Sports and recreation injuries • Malignancy, infections, arthritis and inflammation of the spinal cord also cause spinal cord injuries. Presentation • The primary traumatic impact → oedema and ischaemia → secondary injuries. • Motor, sensory and autonomic dysfunction can occur. The latter → neurogenic shock, paralytic ileus, aspiration, urinary retention, priapism, and loss of thermoregulation. There are two types of injury to the spinal cord: • Non-haemorrhagic with only high signal on MRI due to oedema. • Haemorrhagic with areas of low signal intensity within the area of oedema. There is a strong correlation between the length of the spinal cord oedema and the clinical outcome. The most important factor however is whether there is haemorrhage, since hemorrhagic spinal cord injury has an extremely poor outcome. Spinal cord concussion • Rare. Temporary cessation of spinal cord function, but spontaneous recovery within 48h. Spinal shock • Immediate flaccidity, paralysis, areflexia, & sensation loss below the level of acute SCI • Some reflexes return after a few days & hyperreflexia typical of UMN lesions in weeks. Neurogenic shock • Distributive shock from sympathetic fibre disruption → vasodilatation & hypotension; occurs with high thoracic, cervical spine, and profound brain injuries (SCI above T6) o The triad of hypotension , relative bradycardia , and hypothermia is characteristic • Mx: Fluids, atropine , inotropes Autonomic Dysreflexia – not seen acutely and rare if SCI below T6 • Triggered by afferent stimuli below the level of SCI after spinal shock has worn off.
