Summary
Dynamic MRI aids in diagnosing chronic joint instability in young adults with cervical myelopathy. Anterior cervical interbody fusion (ACIF) surgery shows positive clinical and radiological outcomes.
Area of Science:
- Orthopedics
- Radiology
- Neurosurgery
Background:
- Non-traumatic cervical chronic joint instability is uncommon in young adults.
- This condition is often underexplored, posing diagnostic challenges.
Purpose of the Study:
- To evaluate the diagnostic utility of dynamic MRI for cervical instability.
- To assess clinical and radiological outcomes following anterior cervical interbody fusion (ACIF) for this condition.
Main Methods:
- Dynamic MRI was performed on six young patients (mean age 34) with cervical myelopathy.
- Joint instability was identified by reduced canal diameter on dynamic MRI sequences.
- Clinical and radiological assessments were conducted post-surgery, including X-rays and MRI.
Main Results:
- All patients exhibited joint instability on dynamic MRI.
- Four patients underwent ACIF, reporting improved clinical status at 1-year follow-up.
- Satisfactory fusion and no residual compression were observed at 6-month and 1-year follow-ups, respectively.
Conclusions:
- Dynamic MRI is valuable for detecting joint instability in young patients with cervical myelopathy.
- ACIF demonstrates efficacy in treating non-traumatic cervical chronic joint instability.

20
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

01:29Herniated Intervertebral Disc l: Introduction
40
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

01:25Secondary Spinal Cord Injury llI: Pathophysiology
52
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

01:27Degenerative Disc Disease I: Introduction
29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

01:23Degenerative Disc Disease ll: Pathophysiology
30
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

59
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
