aboutSpinal
Stenosis
Spinal stenosis refers to the narrowing of the spinal canal.
The spinal canal is a well protected space that runs the entire length of the spine.
This space is occupied by the spinal cord and nerve roots.
Any narrowing of the space can therefore put mechanical pressure onto the cord and nerves; resulting in pain and altered sensation.
aboutStenosis
Spinal stenosis is a condition that varies greatly. From occasional and mild symptoms that typically affect both legs, to a condition that limits walking beyond a few steps.
The level of stenosis / spinal canal narrowing is determined by an MRI scan. When symptoms are bad and the MRI indicates stenosis, then surgery may need to be considered.
Symptoms are often eased when the person bends forwards or, for example, leans on a handles of a shopping trolley.
For the majority, spinal stenosis is a normal part of ageing, and whilst it can be frustrating, the level of symptoms would not warrant the risks associated with spinal surgery.
As with all conditions a diagnosis is important and spinal stenosis can often get confused with vascular stenosis.
Vascular stenosis occurs when the blood vessels become narrowed. This restriction to blood flow can also limited walking. Symptoms are generally worse when trying to walk quickly or uphills as the demand for oxygen is increased and the blood flow is unable to deliver.
A specific diagnosis enables a person to select the best treatment and self management for their condition.
