Cervical stenosis is a condition characterized by the narrowing of the spinal canal, potentially impacting the spinal cord and nerve roots. This narrowing can lead to myelopathy, which involves neurologic symptoms related to the spinal cord, or radiculopathy, which is the pinching of nerves as they exit the spinal canal. It is especially concerning in the cervical region (neck) because of the presence of the spinal cord.
In cases such as C5-C6 resulting in central canal and severe left neural foraminal stenosis, various imaging techniques like MRI scans are crucial for evaluating the presence and severity of disc herniations and foraminal stenosis. However, it’s essential to correlate radiological findings with the patient’s symptoms to avoid misinterpretation.
One specialized procedure for addressing cervical spinal pressure is cervical laminoplasty. Unlike traditional spinal surgery, laminoplasty involves reshaping rather than removing bone. The technique aims to relieve pressure without extensive bone removal.
Radiological evaluations might reveal conditions such as anterolisthesis of C3 on C4 and C4 on C5, maintained vertebral body heights, and multilevel degenerative changes, most pronounced at C6-C7. Such findings, including uncovertebral joint degeneration and facet arthropathy, need to be carefully assessed to formulate an accurate impression.
Posterior foraminotomy and discectomy is a long-standing operation for cervical disc disease. It’s typically indicated for disc herniations that are lateralized and is also effective in alleviating arm pain from nerve pressure due to arthritic bone spurs.
In general, spinal stenosis refers to the narrowing of the spinal canal or the foramina, which are the exit points for nerve roots. Treatments and conditions can be researched in depth through reputable sources such as University of Virginia Neurosurgery, UConn Health Spine, Emory Radiology, and HSS Cervical Laminoplasty.
