Summary
The interspinous distance decreases with age in Korean adults, particularly in the lumbar spine. Careful selection of interspinous implants is recommended for younger patients due to this age-related trend.
Area of Science:
- Orthopedic Surgery
- Spinal Anatomy
- Biomedical Engineering
Background:
- Interspinous devices are used for spinal stenosis treatment.
- Accurate morphometric data is crucial for successful device implantation.
- Korean spinal anatomy may differ from other populations.
Purpose of the Study:
- To measure interspinous distance and spinous process dimensions in Korean patients.
- To analyze morphometric variations for interspinous device selection.
- To investigate age-related changes in lumbar interspinous distances.
Main Methods:
- Analysis of plain lumbar and sacral spine radiographs from 60 Korean patients.
- Measurement of interspinous distance and spinous process height, length, and thickness.
- Correlation analysis between age and interspinous distance.
Main Results:
- The largest interspinous distance was observed at L2-3 (mean 12 mm), and the smallest at L5-S1 (mean 8 mm).
- Interspinous distance decreased progressively from L1-2 to L5-S1.
- A significant negative correlation was found between age and interspinous distance at L1-5 levels.
Conclusions:
- Lumbar interspinous distance shows a decreasing trend with advancing age in Korean patients.
- Progressive reduction in interspinous distance necessitates careful consideration during interspinous implant selection, especially for younger individuals.
- These morphometric findings aid in optimizing device choice for Korean populations.
