Spinal stenosis is a narrowing of the spinal canal, which places pressure on the spinal cord. If the stenosis is located on the lower part of the spinal cord it is lumbar spinal stenosis. Stenosis in the upper part of the spinal cord is cervical spinal stenosis. While spinal stenosis can be found in any part of the spine, the lumbar and cervical areas are the most commonly affected. Sometimes such stenosis could be a birth defect. Most often spinal stenosis is seen in patients over 50 years of age. In these patients, stenosis is the gradual result of aging and “wear and tear” on the spine during everyday activities. As people age, the ligaments of the spine thicken and harden (called calcification).
Patients with lumbar spinal stenosis may feel pain, weakness, or numbness in the legs, calves or buttocks specially while walking. Cervical spinal stenosis cause similar symptoms in the shoulders, arms, and legs leading to hand clumsiness and gait and balance disturbances.
Advantages: Spinal stenosis can be treated non –surgically with medications, injections or rest/ restricted activity exercise etc., and surgically with spinal stenosis operation.
Where does spinal stenosis occur?
Spinal stenosis can occur in each section of the spine: cervical, thoracic and lumbar. It is most commonly found in the lumbar spine.
Who Gets Spinal Stenosis?
This disorder is most common in men and women over 50 years of age. However, it may occur in younger people who are born with a narrowing of the spinal canal or who suffer an injury to the spine.
How Is Spinal Stenosis Diagnosed?
The doctor may use a variety of approaches to diagnose spinal stenosis and rule out other conditions: Medical history. Physical examination, X-ray, MRI magnetic resonance imaging, bone scan etc.
Brain tumors are abnormal growth or cancers within the brain. Earlier having a brain tumor meant awaiting certain death.
An Arterio-Venous Malformations (AVM) is a tangle of abnormal and poorly formed blood vessels (arteries and veins), with an innate propensity to bleed. An AVM can occur anywhere in the body, but brain and spinal AVMs present substantial risks when they bleed.
A cranioplasty is performed to correct a deformity or defect of the skull. The deformity/defect could be congenital, as a result of trauma or acquired for example after a previous surgery involving the skull. A craniotomy is the most commonly performed surgery for brain tumour removal.
Lumbar fusion (Arthrodesis) is a major surgery performed to permanently join together two or more bones in the spine so there is no movement between them. These bones are called vertebrae. A lumbar fusion surgery is designed to stop the motion at a painful vertebral segment, which in turn should decrease pain generated from the joint.
Lamina is part of the bone that makes up a vertebra in the spine. Laminectomy is surgery to remove the lamina. Laminectomy is also performed to remove bone spurs in the spine. The procedure helps to reduce the pressure off the spinal nerves or spinal cord.
Aneurysm repair is a surgical procedure to correct an aneurysm, a weak area in a blood vessel wall that causes the blood vessel to bulge or balloon out and sometimes burst (rupture). It may cause:-Bleeding into an area around the brain, heart, abdomen-Bleeding that forms a collection of blood (hematoma)
