Abstract:
The relationship of exiting root and Kambin’s triangle
is discussed in this article. Transforaminal endoscopic
surgery as the gold standard of less invasive lumbar
disc surgeries is performed through Kambin’s triangle.
Existing root damage is one of the most important
complication for this type of surgery. Anatomic variations
in Kambin’s triangle may be the main reason for nerve
root damage during endoscopic lumbar disc surgery.
Kambin’s triangle was investigated with surgical views
and cadaver studies. Thirty-four patients with far lateral
disc herniation were treated with an extraforaminal
approach under the microscope. On the other hand, 48
Kambin’s triangles were dissected on 8 cadavers. Three
main types of triangle were identified, and patients
were grouped according to these 3 types of the triangle.
Only 6 of the 34 patients had type 3 triangles, which is the
wide classical triangle described by Kambin; however, 17
patients had type 2, with a narrow space in the triangle, and 11
patients had type 1, with no space inside the triangle. Cadaver
results were similar; only 10 of the 48 specimens had the type
3 classical triangle, whereas 23 specimens had type 2, and 15
specimens had type 1 triangles. Our results disclosed narrowed
or no space in 82.4% of the patients and 79.2% of the cadavers.
We observed that a wide and safe room of the triangle may not
be exist in some patients. Therefore, more care must be taken
during endoscopic lumbar disc surgery to avoid nerve damage.
