The lateral recess is the space within the spinal canal located toward the sides. It is also located close to the spinal nerve root.
The borders of the lateral recess include the back of the vertebral body and parts of the bony ring known as the pedicle and the superior facet.
Age-related changes in bones, facet joints and/or ligaments may cause these structures to occupy the lateral recess, creating a condition known as spinal stenosis. Because of proximity, these imposing structures may “bump into” the nerve root. This likely will cause pronounced pain.
The lateral recess is part of the spinal canal that may be vulnerable to spinal stenosis.
