Summary
This study measured intervertebral foramina anatomy in human spines. A safe working diameter of 8 mm for L1-L4 and 7 mm for L4-S1 was determined for surgical procedures.
Area of Science:
- Anatomy
- Spine Surgery
- Neurosurgery
Background:
- The intervertebral foramina (IVFs) are critical anatomical structures.
- Understanding IVF dimensions is essential for safe surgical interventions.
- Previous studies have provided variable measurements, necessitating further investigation.
Purpose of the Study:
- To precisely measure the anatomical dimensions of the intervertebral foramina (IVFs) from L1 to S1.
- To establish safe working canal diameters for surgical navigation in the lumbar and sacral spine.
- To provide anatomical data relevant to spinal procedures.
Main Methods:
- Dissection of 13 human anatomic spine specimens.
- Examination of 106 intervertebral foramina levels (L1-S1).
- Systematic measurement of foraminal canal diameters.
Main Results:
- Detailed anatomical measurements of intervertebral foramina (IVFs) L1-S1 were obtained.
- A safe working canal diameter of 8 mm was identified for levels L1-L4.
- A safe working canal diameter of 7 mm was identified for levels L4-S1.
Conclusions:
- The study provides precise anatomical data on lumbar and sacral intervertebral foramina.
- Established safe working diameters can guide surgeons during spinal procedures.
- These findings contribute to enhancing patient safety in spine surgery.
