What does Hemisection of the spinal cord mean?

What does Hemisection of the spinal cord mean?

Definition (NCI) A disorder caused by a spinal injury leading to an incomplete spinal lesion. Patients develop paralysis, ataxia and loss of sensation. Causes include spinal cord tumors, spinal traumas, ischemia, and inflammatory processes affecting the spine. Definition (MSH)

What is the effect of Hemisection of spinal cord?

Brown-Séquard syndrome is a neurologic syndrome resulting from hemisection of the spinal cord. It manifests with weakness or paralysis and proprioceptive deficits on the side of the body ipsilateral to the lesion and loss of pain and temperature sensation on the contralateral side.

Can a T4 paraplegic?

Because a T4 spinal cord injury can result in paralysis or weakness from the chest down, individuals with this level of injury may be unable to sit upright without support or stand on their own.

What causes Brown-Séquard syndrome?

Brown-Séquard syndrome is a rare spinal disorder that results from an injury to one side of the spinal cord in which the spinal cord is damaged but is not severed completely. It is usually caused by an injury to the spine in the region of the neck or back.

What does T4 vertebrae control?

The T4 vertebra, the tenth vertebra down in your spinal column, protects a nerve root that impacts your gall bladder and your common duct. As such, misalignments here can cause problems with liver and gall bladder function, including jaundice and shingles, among others.

What is a T4 injury?

T4 syndrome occurs when the T4 vertebrate in the spine is damaged and causes pain in the arm. The vertebrae bones which make up the spine are named T1 to T12 from top to bottom.

Which tracts are affected in Brown-Séquard syndrome?

Brown-Séquard syndrome results from damage to or loss of ascending and descending spinal cord tracts on 1 side of the spinal cord. Scattered petechial hemorrhages develop in the gray matter and enlarge and coalesce by 1 hour postinjury. Subsequent development of hemorrhagic necrosis occurs within 24-36 hours.

How is Brown-Séquard syndrome diagnosed?

Radiography. Radiographic studies help to confirm the diagnosis and determine the etiology of Brown-Séquard syndrome. Plain films always are required in acute trauma to the spine, but more information usually is obtained by newer techniques. Spinal plain radiographs may depict bony injury in penetrating or blunt trauma …

What is a cape like sensation?

In the early stages, a sense of touch is still present. A loss of feeling may spread over the shoulders and back, described as a “cape-like” distribution. Affected individuals may also develop pain and stiffness (spasticity) in the legs and uncoordinated movements (ataxia), eventually affecting the ability to walk.

What is a T4 spinal cord injury?

The T4 spinal nerves directly affect sensation around the 4 th intercostal space (the area between your 4 th and 5 th rib), which is generally level with the nipples. Therefore, depending on the severity of their injury, someone with a T4 spinal cord injury may not be able to feel or move anything from their chest down.

How does a T4 spinal cord injury affect sitting balance?

The muscles in your core are responsible for maintaining balance between your upper and lower body. Because a T4 spinal cord injury can result in paralysis or weakness from the chest down, individuals with this level of injury may be unable to sit upright without support or stand on their own. Some ways to improve sitting balance include:

What are the T2 and T3 vertebrae?

T2 vertebrae: the posterior aspect of the upper arms. T3 vertebrae: the pectoral area in the chest. T4, T5, T6, T7, & T8 vertebrae: the remaining muscles in the chest and trunk of the body. Spinal cord injuries in the thoracic region are rare due to the rib cage protecting the spine.

What is the difference between the T1-T4 and T5-T8 vertebrae?

The T1-T4 thoracic sections control primarily chest muscles and organs, such as the heart and lungs. The T5 – T8 vertebrae affect the abdominal muscles, as well as some of the chest. The T1-T8 vertebrae are also known as part of the twelve segments of the thoracic vertebrae region.
