What causes anterior cord syndrome?
This syndrome is caused by compression of the anterior spinal artery, which results in anterior cord ischemia or direct compression of the anterior cord. It is associated with burst fractures of the spinal column with fragment retropulsion caused by axial compression.
What is ASA syndrome?
Background Anterior spinal artery (ASA) syndrome results in motor palsy and dissociated sensory loss below the level of the lesion, accompanied by bladder dysfunction. When the cervical spine is involved, breathing disorders may be observed.
Can you walk with posterior cord syndrome?
Can you walk with posterior cord syndrome? Since motor function is carried by the corticospinal tract (i.e. descending motor tracts) of the anterior spinal cord, most people with posterior cord syndrome are able to walk.
What does the anterior spinal artery supply?
The anterior spinal artery is a major artery providing nutrient-rich blood supply to the entire spinal cord section except for the dorsal columns. This artery runs along the entire length of the spinal cord anastomosing with other arteries.
Is central cord syndrome permanent?
There is no cure for central cord syndrome although some people recover near-normal function. There is no standard course of treatment, although drug therapy, surgery, and rest are often part of the program.
How is anterior cord syndrome diagnosed?
MRI is the primary imaging modality in the diagnosis of anterior cord syndrome. T2 hyperintensities within the region of the anterior horns are the hallmark finding. These hyperintensities on the sagittal view appear as thin “pencil-like” lesions extending vertically across several spinal levels.
What is Brown sequard syndrome symptoms?
Definition. Brown-Sequard syndrome (BSS) is a rare neurological condition characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side.
What is the most common cord syndrome?
Central cord syndrome is the most common type of incomplete cord injury and almost always occurs due to a traumatic injury. It results in motor deficits that are worse in the upper extremities as compared to the lower extremities.
Which is the most common type of spinal cord syndrome?
According to the National Spinal Cord Injury Statistical Center (NSCISC), the two most common types of spinal cord injuries are incomplete tetraplegia and paraplegia, with incomplete spinal cord injuries accounting for more than 65% of all SCIs.
Where does anterior spinal artery arise?
The anterior spinal artery arises from the anastomosis of two branches from the intracranial vertebral arteries. It travels in the anterior sulcus of the spinal cord and extends from the level of the olivary nucleus to the conus medullaris.
What nerves are affected by C1 and C2?
C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head. (C1 does not have a dermatome.)
What does anterior spinal artery syndrome mean?
Anterior spinal artery syndrome. Anterior spinal artery syndrome (also known as “anterior spinal cord syndrome”) is syndrome caused by ischemia of the anterior spinal artery, resulting in loss of function of the anterior two-thirds of the spinal cord.
What are symptoms of central cord syndrome?
Symptoms of central cord syndrome include weakness and loss of feeling in limbs, loss of pain and temperature sensation, and loss of sensation of light touch and position. Site of lesion in CCS.
What causes cervical spine lesions?
Cervical Radiculopathy is caused by anything that injures or compresses the nerve root as it travels out from the spine. Injury, arthritis, and spread of cancerous lesions are all potential causes. Plain spine films may show arthritis or metastatic disease.
Is tethered spinal cord syndrome hereditary?
Some researchers have speculated that some cases of tethered cord syndrome that occur due to anomalies that can cause stretching of the spinal cord may have a genetic basis or that some individuals are genetically predisposed to developing the disorder in these specific cases.
