The spinal canal may become narrowed due to abscesses, granulation tissue, or direct dural invasion resulting in compression of cord and neurological deficits. [3] Kyphosis is a result of the front of the spine collapsing. Injury to the thoracic spine are more likely to result in kyphosis compared to lumbar spine injuries. [3]
A spinal epidural abscess (SEA) is a collection of pus or inflammatory granulation between the dura mater and the vertebral column. [1] Currently the annual incidence rate of SEAs is estimated to be 2.5–3 per 10,000 hospital admissions.
An MRI of the lumbar spine with abscess that resulted in CES. Cauda equina syndrome is a rare syndrome that affects the spinal nerves in the region of the lower back called the cauda equine (Latin for "horses tail"). Injury to the cauda equina can have long lasting ramifications for the individual.
Causes can be bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc or other lesion. When acute it can cause a medical emergency independent of its cause, and require swift diagnosis and treatment to prevent long-term disability due to irreversible spinal cord injury.
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can ...
The stratified squamous epithelium of the congenital dermal sinus tract can extend to the spinal fascia of the dura mater or all the way to the spinal cord. [ 4 ] [ 5 ] Thus, the congenital dermal sinus forms a point of entry for infection, this can allow for the formation of an abscess , especially among children.
The most common form of myelopathy in humans, cervical spondylotic myelopathy (CSM), [2] [3] also called degenerative cervical myelopathy, [4] results from narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord. [5] When due to trauma, myelopathy is known as (acute) spinal cord injury.
At each level of the spinal column, spinal nerves branch off from either side of the spinal cord and exit between a pair of vertebrae, to innervate a specific part of the body. The area of skin innervated by a specific spinal nerve is called a dermatome , and the group of muscles innervated by a single spinal nerve is called a myotome .
