The research included 59 volunteers. Here are eight findings from the study:
- Overall foraminal height decreased with age
- Foraminal height in males decreased at all levels with age
- Foraminal height in females did not decrease at all levels
- Foraminal height was significantly larger in the upper lumbar levels
- Foraminal height was smaller in males than females
- Foraminal width decreased with age in both sexes
- Foraminal widths at the lower lumbar levels were smaller than those at the upper levels
- Age-related foraminal width decreased at all lumbar levels
The information can be used as baseline data for diagnosing foraminal stenosis and treating modality planning, concluded the study authors.
