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. -

Neurological involvement in cervical spondylosis usually the buckled hypertrophic ligament flavum compresses the implies radiculopathy or myelopathy. Cervical spondylotic cord. Ischemia due to compromise of microcirculation and myelopathy is the commonest cause of myelopathy in the venous congestion, leading to focal demyelination.3 geriatric age group,1 and often an accompaniment in adult Syringomyelia is an extremely rare sequel of chronic cervical patients manifesting central cord syndrome and spinal cord cord compression due to spondylotic process, and manifests as injury without radiographic abnormality. Myelopathy is the accelerated myelopathy (►Fig. 1). Pathogenesis of result of three factors that often overlap: mechanical factors, syringomyelia is uncertain. Al-Mefty et al4 postulated dynamic-repeated microtrauma, and ischemia of spinal cord occurrence of myelomalacia due to chronic compression of microcirculation.2 Age-related mechanical changes include the cord, followed by phagocytosis, leading to a formation of hypertrophy of the ligamentum flavum, formation of the cavity that extends further. However, Kimura et al5 osteophytic bars, degenerative disc prolapse, all of them disagreed with this hypothesis, and postulated that following contributing to a narrowing of the spinal canal. Degenerative compression of the cord, there is slosh effect cranially and kyphosis and subluxation often aggravates the existing caudally, leading to an extension of the syrinx. It is thus likely compressiononthespinalcord.Flexion–extension that focal cord cavitation due to compression and ischemia movements of the spinal cord places additional, dynamic occurs due to periventricular fluid egress into the cord, the stretch on the cord that is compressed. -

Spinal Cord Injury in Forty-Four Patients with Cervical Spondylosis*
Paraplt:/?iu 24 1,]Y86': 301-106 1986 International Medical Society of Paraplegia Spinal Cord Injury in Forty-four Patients with Cervical Spondylosis* Dominic Foo, M.D. Spinal Cord Injury and Neurology Services, West Roxbury Veterans Adminis tration Medical Center and Department of Neurology, Harvard Medical School, Boston, Massachusetts, U.S.A. Summary Within a 12-year period, 44 (9·4()()) of 466 patients had spinal cord injury compli cating cervical spondylosis. A history of alcoholic use preceding the accident was obtained in 12 (54.5° ,, ) of 22 patients whose cord injury was due to a minor fall. The initial myelopathy was complete in 10 patients and incomplete in 34. Although neurological recovery was seen in the majority of the patients with incomplete cord lesion, complete recovery was unusual and most of the patients were partly or completely wheelchair dependent. No patient developed acute neurological deteriora tion after injury but seven expired. The mortality rate was much higher in the patients whose initial cord lesion was complete (SaO () or 5/10) than in those with incomplete myelopathy (5.9°0 or 2/34). There was no delayed neurological deterioration due to progressive spondylosis of the spine but three patients developed post-traumatic syringomyelia several months to several years after the injury. Key words: Cervical spondylosis; Spinal cord injury; Spinal fracture; Syringo myelia; Mortality. Introduction There have been many publications in the literature on the association between cervical spondylosis and spinal cord injury with regard to the cause and mechan ism of the injury, clinical presentation, radiological features, and autopsy findings (Hardy, 1977; Hughes and Brownell, 1963; Schneider et al., 1954; Symonds, 1953; Young et al., 1977-78). -

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. -
Clinical Outcomes of Cervical Spinal Cord Injuries Without Radiographic Evidence of Trauma
Spinal Cord (1998) 36, 567 ± 573 1998 International Medical Society of Paraplegia All rights reserved 1362 ± 4393/98 $12.00 http://www.stockton-press.co.uk/sc Clinical outcomes of cervical spinal cord injuries without radiographic evidence of trauma Yasuo Saruhashi, Sinsuke Hukuda, Akitomo Katsuura, Shuzo Asajima and Kikuo Omura Department of Orthopaedic Surgery, Shiga University of Medical Science, Setatsukinowacho, Otsu, Shiga 520-21, Japan We investigated 33 cervical spinal cord injury patients (25 males and eight females) without bony injury. Patients whose neurologic recovery had reached a plateau and who had evidence on imaging of persistent spinal cord compression were considered candidates for surgical decompression. When imaging did not show spinal cord compression or patients were maintaining a good neurologic recovery from the early days after injury, we pursued conservative treatment. Age at injury varied from 20 to 76 years (mean, 55.6). Average follow- up was 31 months. Twelve patients were treated conservatively (Group 1). Groups 2 and 3 had surgery. Group 2 (14 cases) had multi-level compression of spinal cord due to pre-existing cervical spine conditions such as ossi®cation of posterior longitudinal ligament, cervical canal stenosis, and cervical spondylosis. Group 3 (7 cases) patients existed single-level compression of spinal cord by cervical disc herniations or spondylosis. We evaluated clinical results according to the Frankel classi®cation, the American Spinal Injury Association (ASIA) scales and Japanese Orthopaedic Association (JOA) scores. Overall improvement of JOA and ASIA scores after treatment was 56.3+35.5% and 67.1+38.0%, respectively. Patients in Group 1 showed very good recovery after conservative treatment, with improvement of JOA and ASIA scores being 70.4+40.2% and 77.4+34.2%, respectively. -
