Lateral recess stenosis: Definition, Uses, and Clinical Overview
Lateral recess stenosis is a narrowing of a side channel in the spinal canal where a nerve root travels. It most often refers to narrowing in the lower back, but it can also occur in the neck. It is commonly discussed when explaining sciatica-like leg pain or arm symptoms from nerve irritation. Clinicians use the term to describe both imaging findings and a potential cause of nerve-related symptoms.
