Anterolisthesis of C3 on C4 and C4 on C5 suggests forward displacement of the vertebrae, which can impact spinal stability and nerve function. The vertebral body heights are maintained, indicating no significant compression fracture. Multilevel degenerative changes, including disc space narrowing, uncovertebral joint degeneration, and facet arthropathy, are most pronounced at the C6-C7 level. The prevertebral soft tissues appear normal.
Typical cervical vertebrae, like C4 or C5, are characterized by their small bodies and bifid, or Y-shaped, spinous processes, which distinguish them from thoracic or lumbar vertebrae. A cervical vertebra‘s small size reflects the relatively lighter weight it bears compared to other spinal regions.
In cases where the spinal cord or nerves are compressed by damaged vertebrae or discs, a corpectomy may be performed. This surgical procedure involves removing the affected vertebral components, often through an anterior (frontal) approach.
For conditions like spinal stenosis, where the spinal canal narrows and compresses the spinal cord, decompression surgery such as a cervical laminectomy might be recommended. This involves removing parts of the vertebrae to relieve pressure on the spinal cord, addressing symptoms such as pain and mobility issues.
Injuries or conditions at the higher levels of the cervical spine, such as C3, C4, and C5, carry risks of severe complications, including the loss of diaphragm function and paralysis. A spinal cord injury at these levels may necessitate the use of a ventilator and result in the loss of function in multiple body areas.
An alternative to more invasive procedures is the cervical laminoplasty, a specialized surgery that reshapes rather than removes bone to alleviate pressure on the spinal cord.
The cervical region, consisting of vertebrae C1-C7, supports the head’s weight and enables a significant range of motion. Injuries to the cervical spine, particularly above the C5 level, can be life-threatening due to their potential to compromise respiratory functions.
Understanding the mechanisms behind cervical spine injuries is crucial for appropriate management and treatment.
